Forms

The <FormControl> component renders a form control with Bootstrap styling. The <FormGroup> component wraps a form control with proper spacing, along with support for a label, help text, and validation state. To ensure accessibility, set controlId on <FormGroup>, and use <FormLabel> for the label.

<Form>
  <Form.Group controlId="formBasicEmail">
    <Form.Label>Email address</Form.Label>
    <Form.Control type="email" placeholder="Enter email" />
    <Form.Text className="text-muted">
      We'll never share your email with anyone else.
    </Form.Text>
  </Form.Group>

  <Form.Group controlId="formBasicPassword">
    <Form.Label>Password</Form.Label>
    <Form.Control type="password" placeholder="Password" />
  </Form.Group>
  <Form.Group controlId="formBasicCheckbox">
    <Form.Check type="checkbox" label="Check me out" />
  </Form.Group>
  <Button variant="primary" type="submit">
    Submit
  </Button>
</Form>

<Form>
  <Form.Group controlId="formBasicEmail">
    <Form.Label>Email address</Form.Label>
    <Form.Control type="email" placeholder="Enter email" />
    <Form.Text className="text-muted">
      We'll never share your email with anyone else.
    </Form.Text>
  </Form.Group>
  <Form.Group controlId="formBasicPassword">
    <Form.Label>Password</Form.Label>
    <Form.Control type="password" placeholder="Password" />
  </Form.Group>
  <Form.Group controlId="formBasicCheckbox">
    <Form.Check type="checkbox" label="Check me out" />
  </Form.Group>
  <Button variant="primary" type="submit">
    Submit
  </Button>
</Form>

The <FormControl> component directly renders the <input> or other specified component. If you need to access the value of an uncontrolled <FormControl>, attach a ref to it as you would with an uncontrolled input, then call ReactDOM.findDOMNode(ref) to get the DOM node. You can then interact with that node as you would with any other uncontrolled input.

If your application contains a large number of form groups, we recommend building a higher-level component encapsulating a complete field group that renders the label, the control, and any other necessary components. We don't provide this out-of-the-box, because the composition of those field groups is too specific to an individual application to admit a good one-size-fits-all solution.

Form controls

For textual form controls—like inputs, selects, and textareas—use the FormControl component. FormControl adds some additional styles for general appearance, focus state, sizing, and more.

<Form>
  <Form.Group controlId="exampleForm.ControlInput1">
    <Form.Label>Email address</Form.Label>
    <Form.Control type="email" placeholder="name@example.com" />
  </Form.Group>
  <Form.Group controlId="exampleForm.ControlSelect1">
    <Form.Label>Example select</Form.Label>
    <Form.Control as="select">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
  <Form.Group controlId="exampleForm.ControlSelect2">
    <Form.Label>Example multiple select</Form.Label>
    <Form.Control as="select" multiple>
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
  <Form.Group controlId="exampleForm.ControlTextarea1">
    <Form.Label>Example textarea</Form.Label>
    <Form.Control as="textarea" rows={3} />
  </Form.Group>
</Form>

<Form>
  <Form.Group controlId="exampleForm.ControlInput1">
    <Form.Label>Email address</Form.Label>
    <Form.Control type="email" placeholder="name@example.com" />
  </Form.Group>
  <Form.Group controlId="exampleForm.ControlSelect1">
    <Form.Label>Example select</Form.Label>
    <Form.Control as="select">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
  <Form.Group controlId="exampleForm.ControlSelect2">
    <Form.Label>Example multiple select</Form.Label>
    <Form.Control as="select" multiple>
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
  <Form.Group controlId="exampleForm.ControlTextarea1">
    <Form.Label>Example textarea</Form.Label>
    <Form.Control as="textarea" rows={3} />
  </Form.Group>
</Form>

For file inputs, use Form.File.

<Form>
  <Form.Group>
    <Form.File id="exampleFormControlFile1" label="Example file input" />
  </Form.Group>
</Form>

<Form>
  <Form.Group>
    <Form.File id="exampleFormControlFile1" label="Example file input" />
  </Form.Group>
</Form>

Sizing

Use size on <FormControl> and <FormLabel> to change the size of inputs and labels respectively.

<Form.Group>
  <Form.Control size="lg" type="text" placeholder="Large text" />
  <br />
  <Form.Control type="text" placeholder="Normal text" />
  <br />
  <Form.Control size="sm" type="text" placeholder="Small text" />
</Form.Group>

<Form.Group>
  <Form.Control size="lg" type="text" placeholder="Large text" />
  <br />
  <Form.Control type="text" placeholder="Normal text" />
  <br />
  <Form.Control size="sm" type="text" placeholder="Small text" />
</Form.Group>

<Form.Group>
  <Form.Control as="select" size="lg">
    <option>Large select</option>
  </Form.Control>
  <br />
  <Form.Control as="select">
    <option>Default select</option>
  </Form.Control>
  <br />
  <Form.Control size="sm" as="select">
    <option>Small select</option>
  </Form.Control>
</Form.Group>

<Form.Group>
  <Form.Control as="select" size="lg">
    <option>Large select</option>
  </Form.Control>
  <br />
  <Form.Control as="select">
    <option>Default select</option>
  </Form.Control>
  <br />
  <Form.Control size="sm" as="select">
    <option>Small select</option>
  </Form.Control>
</Form.Group>

Readonly

Add the readOnly prop on an input to prevent modification of the input's value. Read-only inputs appear lighter (just like disabled inputs), but retain the standard cursor.

<Form.Control type="text" placeholder="Readonly input here..." readOnly />

<Form.Control type="text" placeholder="Readonly input here..." readOnly />

Readonly plain text

If you want to have readonly elements in your form styled as plain text, use the plaintext prop on FormControls to remove the default form field styling and preserve the correct margin and padding.

<Form>
  <Form.Group as={Row} controlId="formPlaintextEmail">
    <Form.Label column sm="2">
      Email
    </Form.Label>
    <Col sm="10">
      <Form.Control plaintext readOnly defaultValue="email@example.com" />
    </Col>
  </Form.Group>

  <Form.Group as={Row} controlId="formPlaintextPassword">
    <Form.Label column sm="2">
      Password
    </Form.Label>
    <Col sm="10">
      <Form.Control type="password" placeholder="Password" />
    </Col>
  </Form.Group>
</Form>

<Form>
  <Form.Group as={Row} controlId="formPlaintextEmail">
    <Form.Label column sm="2">
      Email
    </Form.Label>
    <Col sm="10">
      <Form.Control plaintext readOnly defaultValue="email@example.com" />
    </Col>
  </Form.Group>
  <Form.Group as={Row} controlId="formPlaintextPassword">
    <Form.Label column sm="2">
      Password
    </Form.Label>
    <Col sm="10">
      <Form.Control type="password" placeholder="Password" />
    </Col>
  </Form.Group>
</Form>

Range Inputs

<Form>
  <Form.Group controlId="formBasicRange">
    <Form.Label>Range</Form.Label>
    <Form.Control type="range" />
  </Form.Group>
</Form>

<Form>
  <Form.Group controlId="formBasicRange">
    <Form.Label>Range</Form.Label>
    <Form.Control type="range" />
  </Form.Group>
</Form>

Checkboxes and Radios

For the non-textual checkbox and radio controls, FormCheck provides a single component for both types that adds some additional styling and improved layout.

Default (stacked)

By default, any number of checkboxes and radios that are immediate sibling will be vertically stacked and appropriately spaced with FormCheck.

<Form>
  {['checkbox', 'radio'].map((type) => (
    <div key={`default-${type}`} className="mb-3">
      <Form.Check 
        type={type}
        id={`default-${type}`}
        label={`default ${type}`}
      />

      <Form.Check
        disabled
        type={type}
        label={`disabled ${type}`}
        id={`disabled-default-${type}`}
      />
    </div>
  ))}
</Form>

<Form>
  {['checkbox', 'radio'].map((type) => (
    <div key={`default-${type}`} className="mb-3">
      <Form.Check 
        type={type}
        id={`default-${type}`}
        label={`default ${type}`}
      />
      <Form.Check
        disabled
        type={type}
        label={`disabled ${type}`}
        id={`disabled-default-${type}`}
      />
    </div>
  ))}
</Form>

Inline

Group checkboxes or radios on the same horizontal row by adding the inline prop.

<Form>
  {['checkbox', 'radio'].map((type) => (
    <div key={`inline-${type}`} className="mb-3">
      <Form.Check inline label="1" name="group1" type={type} id={`inline-${type}-1`} />
      <Form.Check inline label="2" name="group1" type={type} id={`inline-${type}-2`} />
      <Form.Check
        inline
        disabled
        label="3 (disabled)"
        type={type}
        id={`inline-${type}-3`}
      />
    </div>
  ))}
</Form>

<Form>
  {['checkbox', 'radio'].map((type) => (
    <div key={`inline-${type}`} className="mb-3">
      <Form.Check inline label="1" name="group1" type={type} id={`inline-${type}-1`} />
      <Form.Check inline label="2" name="group1" type={type} id={`inline-${type}-2`} />
      <Form.Check
        inline
        disabled
        label="3 (disabled)"
        type={type}
        id={`inline-${type}-3`}
      />
    </div>
  ))}
</Form>

Without labels

When you render a FormCheck without a label (no children) some additional styling is applied to keep the inputs from collapsing. Remember to add an aria-label when omitting labels!

<>
  <Form.Check aria-label="option 1" />
  <Form.Check type="radio" aria-label="radio 1" />
</>

<>
  <Form.Check aria-label="option 1" />
  <Form.Check type="radio" aria-label="radio 1" />
</>

Customizing FormCheck rendering

When you need tighter control, or want to customize how the FormCheck component renders, it may better to use it's constituent parts directly.

By provided children to the FormCheck you can forgo the default rendering and handle it yourself. (You can still provide an id to the FormCheck or FormGroup and have it propagate to the label and input).

<Form>
  {['checkbox', 'radio'].map((type) => (
    <div key={type} className="mb-3">
      <Form.Check type={type} id={`check-api-${type}`}>
        <Form.Check.Input type={type} isValid />
        <Form.Check.Label>{`Custom api ${type}`}</Form.Check.Label>
        <Form.Control.Feedback type="valid">You did it!</Form.Control.Feedback>
      </Form.Check>
    </div>
  ))}
</Form>

<Form>
  {['checkbox', 'radio'].map((type) => (
    <div key={type} className="mb-3">
      <Form.Check type={type} id={`check-api-${type}`}>
        <Form.Check.Input type={type} isValid />
        <Form.Check.Label>{`Custom api ${type}`}</Form.Check.Label>
        <Form.Control.Feedback type="valid">You did it!</Form.Control.Feedback>
      </Form.Check>
    </div>
  ))}
</Form>

Layout

FormControl and FormCheck both apply display: block with width: 100% to controls, which means they stack vertically by default. Additional components and props can be used to vary this layout on a per-form basis.

Form groups

The FormGroup component is the easiest way to add some structure to forms. It provides a flexible container for grouping of labels, controls, optional help text, and form validation messaging. By default it only applies margin-bottom, but it picks up additional styles in <Form inline > as needed. Use it with fieldsets, divs, or nearly any other element.

You also add the controlId prop to accessibly wire the nested label and input together via the id.

<Form>
  <Form.Group controlId="formGroupEmail">
    <Form.Label>Email address</Form.Label>
    <Form.Control type="email" placeholder="Enter email" />
  </Form.Group>
  <Form.Group controlId="formGroupPassword">
    <Form.Label>Password</Form.Label>
    <Form.Control type="password" placeholder="Password" />
  </Form.Group>
</Form>

<Form>
  <Form.Group controlId="formGroupEmail">
    <Form.Label>Email address</Form.Label>
    <Form.Control type="email" placeholder="Enter email" />
  </Form.Group>
  <Form.Group controlId="formGroupPassword">
    <Form.Label>Password</Form.Label>
    <Form.Control type="password" placeholder="Password" />
  </Form.Group>
</Form>

Form grid

More complex forms can be built using the grid components. Use these for form layouts that require multiple columns, varied widths, and additional alignment options.

<Form>
  <Row>
    <Col>
      <Form.Control placeholder="First name" />
    </Col>
    <Col>
      <Form.Control placeholder="Last name" />
    </Col>
  </Row>
</Form>

<Form>
  <Row>
    <Col>
      <Form.Control placeholder="First name" />
    </Col>
    <Col>
      <Form.Control placeholder="Last name" />
    </Col>
  </Row>
</Form>

Form row

You may also swap <Row> for <Form.Row>, a variation of the standard grid row that overrides the default column gutters for tighter and more compact layouts.

<Form>
  <Form.Row>
    <Col>
      <Form.Control placeholder="First name" />
    </Col>
    <Col>
      <Form.Control placeholder="Last name" />
    </Col>
  </Form.Row>
</Form>

<Form>
  <Form.Row>
    <Col>
      <Form.Control placeholder="First name" />
    </Col>
    <Col>
      <Form.Control placeholder="Last name" />
    </Col>
  </Form.Row>
</Form>

More complex layouts can also be created with the grid system.

<Form>
  <Form.Row>
    <Form.Group as={Col} controlId="formGridEmail">
      <Form.Label>Email</Form.Label>
      <Form.Control type="email" placeholder="Enter email" />
    </Form.Group>

    <Form.Group as={Col} controlId="formGridPassword">
      <Form.Label>Password</Form.Label>
      <Form.Control type="password" placeholder="Password" />
    </Form.Group>
  </Form.Row>

  <Form.Group controlId="formGridAddress1">
    <Form.Label>Address</Form.Label>
    <Form.Control placeholder="1234 Main St" />
  </Form.Group>

  <Form.Group controlId="formGridAddress2">
    <Form.Label>Address 2</Form.Label>
    <Form.Control placeholder="Apartment, studio, or floor" />
  </Form.Group>

  <Form.Row>
    <Form.Group as={Col} controlId="formGridCity">
      <Form.Label>City</Form.Label>
      <Form.Control />
    </Form.Group>

    <Form.Group as={Col} controlId="formGridState">
      <Form.Label>State</Form.Label>
      <Form.Control as="select" defaultValue="Choose...">
        <option>Choose...</option>
        <option>...</option>
      </Form.Control>
    </Form.Group>

    <Form.Group as={Col} controlId="formGridZip">
      <Form.Label>Zip</Form.Label>
      <Form.Control />
    </Form.Group>
  </Form.Row>

  <Form.Group id="formGridCheckbox">
    <Form.Check type="checkbox" label="Check me out" />
  </Form.Group>

  <Button variant="primary" type="submit">
    Submit
  </Button>
</Form>

<Form>
  <Form.Row>
    <Form.Group as={Col} controlId="formGridEmail">
      <Form.Label>Email</Form.Label>
      <Form.Control type="email" placeholder="Enter email" />
    </Form.Group>
    <Form.Group as={Col} controlId="formGridPassword">
      <Form.Label>Password</Form.Label>
      <Form.Control type="password" placeholder="Password" />
    </Form.Group>
  </Form.Row>
  <Form.Group controlId="formGridAddress1">
    <Form.Label>Address</Form.Label>
    <Form.Control placeholder="1234 Main St" />
  </Form.Group>
  <Form.Group controlId="formGridAddress2">
    <Form.Label>Address 2</Form.Label>
    <Form.Control placeholder="Apartment, studio, or floor" />
  </Form.Group>
  <Form.Row>
    <Form.Group as={Col} controlId="formGridCity">
      <Form.Label>City</Form.Label>
      <Form.Control />
    </Form.Group>
    <Form.Group as={Col} controlId="formGridState">
      <Form.Label>State</Form.Label>
      <Form.Control as="select" defaultValue="Choose...">
        <option>Choose...</option>
        <option>...</option>
      </Form.Control>
    </Form.Group>
    <Form.Group as={Col} controlId="formGridZip">
      <Form.Label>Zip</Form.Label>
      <Form.Control />
    </Form.Group>
  </Form.Row>
  <Form.Group id="formGridCheckbox">
    <Form.Check type="checkbox" label="Check me out" />
  </Form.Group>
  <Button variant="primary" type="submit">
    Submit
  </Button>
</Form>

Horizontal form

You may also swap <Row> for <Form.Row>, a variation of the standard grid row that overrides the default column gutters for tighter and more compact layouts.

<Form>
  <Form.Group as={Row} controlId="formHorizontalEmail">
    <Form.Label column sm={2}>

    </Col>
  </Form.Group>
  <fieldset>
    <Form.Group as={Row}>
      <Form.Label as="legend" column sm={2}>
        Radios

  </Form.Row>
  <br />
  <Form.Row>
    <Form.Label column lg={2}>
      Normal Text
    </Form.Label>
    <Col>
      <Form.Control type="text" placeholder="Normal text" />
    </Col>
  </Form.Row>
  <br />
  <Form.Row>
    <Form.Label column="sm" lg={2}>
      Small Text
    </Form.Label>
    <Col>
      <Form.Control size="sm" type="text" placeholder="Small text" />
    </Col>
  </Form.Row>
</Form.Group>

Column sizing

As shown in the previous examples, our grid system allows you to place any number of <Col>s within a <Row> or <Form.Row>. They'll split the available width equally between them. You may also pick a subset of your columns to take up more or less space, while the remaining <Col>s equally split the rest, with specific column classes like <Col xs={7}>.

<Form>
  <Form.Row>
    <Col xs={7}>
      <Form.Control placeholder="City" />
    </Col>
    <Col>
      <Form.Control placeholder="State" />
    </Col>
    <Col>
      <Form.Control placeholder="Zip" />
    </Col>
  </Form.Row>
</Form>

<Form>
  <Form.Row>
    <Col xs={7}>
      <Form.Control placeholder="City" />
    </Col>
    <Col>
      <Form.Control placeholder="State" />
    </Col>
    <Col>
      <Form.Control placeholder="Zip" />
    </Col>
  </Form.Row>
</Form>

Auto-sizing

The example below uses a flexbox utility to vertically center the contents and changes <Col> to <Col xs="auto"> so that your columns only take up as much space as needed. Put another way, the column sizes itself based on on the contents.

<Form>
  <Form.Row className="align-items-center">
    <Col xs="auto">
      <Form.Label htmlFor="inlineFormInput" srOnly>
        Name
      </Form.Label>
      <Form.Control
        className="mb-2"
        id="inlineFormInput"
        placeholder="Jane Doe"
      />
    </Col>
    <Col xs="auto">
      <Form.Label htmlFor="inlineFormInputGroup" srOnly>
        Username
      </Form.Label>
      <InputGroup className="mb-2">
        <InputGroup.Prepend>
          <InputGroup.Text>@</InputGroup.Text>
        </InputGroup.Prepend>
        <FormControl id="inlineFormInputGroup" placeholder="Username" />
      </InputGroup>
    </Col>
    <Col xs="auto">
      <Form.Check
        type="checkbox"
        id="autoSizingCheck"
        className="mb-2"
        label="Remember me"
      />
    </Col>
    <Col xs="auto">
      <Button type="submit" className="mb-2">
        Submit
      </Button>
    </Col>
  </Form.Row>
</Form>

<Form>
  <Form.Row className="align-items-center">
    <Col xs="auto">
      <Form.Label htmlFor="inlineFormInput" srOnly>
        Name
      </Form.Label>
      <Form.Control
        className="mb-2"
        id="inlineFormInput"
        placeholder="Jane Doe"
      />
    </Col>
    <Col xs="auto">
      <Form.Label htmlFor="inlineFormInputGroup" srOnly>
        Username
      </Form.Label>
      <InputGroup className="mb-2">
        <InputGroup.Prepend>
          <InputGroup.Text>@</InputGroup.Text>
        </InputGroup.Prepend>
        <FormControl id="inlineFormInputGroup" placeholder="Username" />
      </InputGroup>
    </Col>
    <Col xs="auto">
      <Form.Check
        type="checkbox"
        id="autoSizingCheck"
        className="mb-2"
        label="Remember me"
      />
    </Col>
    <Col xs="auto">
      <Button type="submit" className="mb-2">
        Submit
      </Button>
    </Col>
  </Form.Row>
</Form>

You can then remix that once again with size-specific column classes.

<Form>
  <Form.Row className="align-items-center">
    <Col sm={3} className="my-1">
      <Form.Label htmlFor="inlineFormInputName" srOnly>
        Name
      </Form.Label>
      <Form.Control id="inlineFormInputName" placeholder="Jane Doe" />
    </Col>
    <Col sm={3} className="my-1">
      <Form.Label htmlFor="inlineFormInputGroupUsername" srOnly>
        Username
      </Form.Label>
      <InputGroup>
        <InputGroup.Prepend>
          <InputGroup.Text>@</InputGroup.Text>
        </InputGroup.Prepend>
        <FormControl id="inlineFormInputGroupUsername" placeholder="Username" />
      </InputGroup>
    </Col>
    <Col xs="auto" className="my-1">
      <Form.Check type="checkbox" id="autoSizingCheck2" label="Remember me" />
    </Col>
    <Col xs="auto" className="my-1">
      <Button type="submit">Submit</Button>
    </Col>
  </Form.Row>
</Form>

<Form>
  <Form.Row className="align-items-center">
    <Col sm={3} className="my-1">
      <Form.Label htmlFor="inlineFormInputName" srOnly>
        Name
      </Form.Label>
      <Form.Control id="inlineFormInputName" placeholder="Jane Doe" />
    </Col>
    <Col sm={3} className="my-1">
      <Form.Label htmlFor="inlineFormInputGroupUsername" srOnly>
        Username
      </Form.Label>
      <InputGroup>
        <InputGroup.Prepend>
          <InputGroup.Text>@</InputGroup.Text>
        </InputGroup.Prepend>
        <FormControl id="inlineFormInputGroupUsername" placeholder="Username" />
      </InputGroup>
    </Col>
    <Col xs="auto" className="my-1">
      <Form.Check type="checkbox" id="autoSizingCheck2" label="Remember me" />
    </Col>
    <Col xs="auto" className="my-1">
      <Button type="submit">Submit</Button>
    </Col>
  </Form.Row>
</Form>

And of course custom form controls are supported.

<Form>
  <Form.Row className="align-items-center">
    <Col xs="auto" className="my-1">
      <Form.Label className="mr-sm-2" htmlFor="inlineFormCustomSelect" srOnly>
        Preference
      </Form.Label>
      <Form.Control
        as="select"
        className="mr-sm-2"
        id="inlineFormCustomSelect"
        custom
      >
        <option value="0">Choose...</option>
        <option value="1">One</option>
        <option value="2">Two</option>
        <option value="3">Three</option>
      </Form.Control>
    </Col>
    <Col xs="auto" className="my-1">
      <Form.Check
        type="checkbox"
        id="customControlAutosizing"
        label="Remember my preference"
        custom
      />
    </Col>
    <Col xs="auto" className="my-1">
      <Button type="submit">Submit</Button>
    </Col>
  </Form.Row>
</Form>

<Form>
  <Form.Row className="align-items-center">
    <Col xs="auto" className="my-1">
      <Form.Label className="mr-sm-2" htmlFor="inlineFormCustomSelect" srOnly>
        Preference
      </Form.Label>
      <Form.Control
        as="select"
        className="mr-sm-2"
        id="inlineFormCustomSelect"
        custom
      >
        <option value="0">Choose...</option>
        <option value="1">One</option>
        <option value="2">Two</option>
        <option value="3">Three</option>
      </Form.Control>
    </Col>
    <Col xs="auto" className="my-1">
      <Form.Check
        type="checkbox"
        id="customControlAutosizing"
        label="Remember my preference"
        custom
      />
    </Col>
    <Col xs="auto" className="my-1">
      <Button type="submit">Submit</Button>
    </Col>
  </Form.Row>
</Form>

Inline forms

Use the inline prop to display a series of labels, form controls, and buttons on a single horizontal row. Form controls within forms vary slightly from their default states.

Controls are display: flex, collapsing any HTML white space and allowing you to provide alignment control with spacing and utilities.
Controls and input groups receive width: auto to override the Bootstrap default width: 100%.
Controls only appear inline in viewports that are at least 576px wide to account for narrow viewports on mobile devices.

You may need to manually address the width and alignment of individual form controls with spacing utilities (as shown below). Lastly, be sure to always include a <Form.Label> with each form control, even if you need to hide it from non-screenreader visitors with the srOnly prop.

<Form inline>
  <Form.Label htmlFor="inlineFormInputName2" srOnly>
    Name
  </Form.Label>
  <Form.Control
    className="mb-2 mr-sm-2"
    id="inlineFormInputName2"
    placeholder="Jane Doe"
  />
  <Form.Label htmlFor="inlineFormInputGroupUsername2" srOnly>
    Username
  </Form.Label>
  <InputGroup className="mb-2 mr-sm-2">
    <InputGroup.Prepend>
      <InputGroup.Text>@</InputGroup.Text>
    </InputGroup.Prepend>
    <FormControl id="inlineFormInputGroupUsername2" placeholder="Username" />
  </InputGroup>
  <Form.Check
    type="checkbox"
    className="mb-2 mr-sm-2"
    id="inlineFormCheck"
    label="Remember me"
  />
  <Button type="submit" className="mb-2">
    Submit
  </Button>
</Form>

<Form inline>
  <Form.Label htmlFor="inlineFormInputName2" srOnly>
    Name
  </Form.Label>
  <Form.Control
    className="mb-2 mr-sm-2"
    id="inlineFormInputName2"
    placeholder="Jane Doe"
  />
  <Form.Label htmlFor="inlineFormInputGroupUsername2" srOnly>
    Username
  </Form.Label>
  <InputGroup className="mb-2 mr-sm-2">
    <InputGroup.Prepend>
      <InputGroup.Text>@</InputGroup.Text>
    </InputGroup.Prepend>
    <FormControl id="inlineFormInputGroupUsername2" placeholder="Username" />
  </InputGroup>
  <Form.Check
    type="checkbox"
    className="mb-2 mr-sm-2"
    id="inlineFormCheck"
    label="Remember me"
  />
  <Button type="submit" className="mb-2">
    Submit
  </Button>
</Form>

Custom form controls and selects are also supported.

<Form inline>
  <Form.Label className="my-1 mr-2" htmlFor="inlineFormCustomSelectPref">
    Preference
  </Form.Label>
  <Form.Control
    as="select"
    className="my-1 mr-sm-2"
    id="inlineFormCustomSelectPref"
    custom
  >
    <option value="0">Choose...</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
  </Form.Control>
  <Form.Check
    type="checkbox"
    className="my-1 mr-sm-2"
    id="customControlInline"
    label="Remember my preference"
    custom
  />
  <Button type="submit" className="my-1">
    Submit
  </Button>
</Form>

<Form inline>
  <Form.Label className="my-1 mr-2" htmlFor="inlineFormCustomSelectPref">
    Preference
  </Form.Label>
  <Form.Control
    as="select"
    className="my-1 mr-sm-2"
    id="inlineFormCustomSelectPref"
    custom
  >
    <option value="0">Choose...</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
  </Form.Control>
  <Form.Check
    type="checkbox"
    className="my-1 mr-sm-2"
    id="customControlInline"
    label="Remember my preference"
    custom
  />
  <Button type="submit" className="my-1">
    Submit
  </Button>
</Form>

Help text

Block-level help text in forms can be created using <Form.Text>. Inline help text can be flexibly implemented using any inline HTML element and utility classes like.text-muted.

Help text below inputs can be styled with <Form.Text>. This component includes display: block and adds some top margin for easy spacing from the inputs above.

PasswordYour password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji.

<>
  <Form.Label htmlFor="inputPassword5">Password</Form.Label>
  <Form.Control
    type="password"
    id="inputPassword5"
    aria-describedby="passwordHelpBlock"
  />
  <Form.Text id="passwordHelpBlock" muted>
    Your password must be 8-20 characters long, contain letters and numbers, and
    must not contain spaces, special characters, or emoji.
  </Form.Text>
</>

<>
  <Form.Label htmlFor="inputPassword5">Password</Form.Label>
  <Form.Control
    type="password"
    id="inputPassword5"
    aria-describedby="passwordHelpBlock"
  />
  <Form.Text id="passwordHelpBlock" muted>
    Your password must be 8-20 characters long, contain letters and numbers, and
    must not contain spaces, special characters, or emoji.
  </Form.Text>
</>

Inline text can use any typical inline HTML element (be it a <small>, <span>, or something else) with nothing more than a utility class.

<Form inline>
  <Form.Group>
    <Form.Label htmlFor="inputPassword6">Password</Form.Label>
    <Form.Control
      type="password"
      className="mx-sm-3"
      id="inputPassword6"
      aria-describedby="passwordHelpInline"
    />
    <Form.Text id="passwordHelpInline" muted>
      Must be 8-20 characters long.
    </Form.Text>
  </Form.Group>
</Form>

<Form inline>
  <Form.Group>
    <Form.Label htmlFor="inputPassword6">Password</Form.Label>
    <Form.Control
      type="password"
      className="mx-sm-3"
      id="inputPassword6"
      aria-describedby="passwordHelpInline"
    />
    <Form.Text id="passwordHelpInline" muted>
      Must be 8-20 characters long.
    </Form.Text>
  </Form.Group>
</Form>

Disabled forms

Add the disabled boolean attribute on an input to prevent user interactions and make it appear lighter.

Disabled input

Disabled select menu

Can't check this

<>
  <Form.Group>
    <Form.Label>Disabled input</Form.Label>
    <Form.Control placeholder="Disabled input" disabled />
  </Form.Group>
  <Form.Group>
    <Form.Label>Disabled select menu</Form.Label>
    <Form.Control as="select" disabled>
      <option>Disabled select</option>
    </Form.Control>
  </Form.Group>
  <Form.Group>
    <Form.Check type="checkbox" label="Can't check this" disabled />
  </Form.Group>
</>

<>
  <Form.Group>
    <Form.Label>Disabled input</Form.Label>
    <Form.Control placeholder="Disabled input" disabled />
  </Form.Group>
  <Form.Group>
    <Form.Label>Disabled select menu</Form.Label>
    <Form.Control as="select" disabled>
      <option>Disabled select</option>
    </Form.Control>
  </Form.Group>
  <Form.Group>
    <Form.Check type="checkbox" label="Can't check this" disabled />
  </Form.Group>
</>

Add the disabled attribute to a <fieldset> to disable all the controls within.

<Form>
  <fieldset disabled>
    <Form.Group>
      <Form.Label htmlFor="disabledTextInput">Disabled input</Form.Label>
      <Form.Control id="disabledTextInput" placeholder="Disabled input" />

      <Form.Control as="select" id="disabledSelect">
        <option>Disabled select</option>
      </Form.Control>
    </Form.Group>
    <Form.Group>
      <Form.Check
        type="checkbox"
        id="disabledFieldsetCheck"
        label="Can't check this"
      />
    </Form.Group>
    <Button type="submit">Submit</Button>
  </fieldset>
</Form>

      />
    </Form.Group>
    <Button type="submit">Submit</Button>
  </fieldset>
</Form>

Validation

Provide valuable, actionable feedback to your users with form validation feedback.

Native HTML5 form validation

For native HTML form validation–available in all our supported browsers, the :valid and :invalid pseudo selectors are used to apply validation styles as well as display feedback messages.

Bootstrap scopes the :valid and :invalid styles to parent .was-validated class, usually applied to the <Form> (you can use the validated prop as a shortcut). Otherwise, any required field without a value shows up as invalid on page load. This way, you may choose when to activate them (typically after form submission is attempted).

function FormExample() {
  const [validated, setValidated] = useState(false);

  const handleSubmit = (event) => {
    const form = event.currentTarget;
    if (form.checkValidity() === false) {
      event.preventDefault();
      event.stopPropagation();
    }

    setValidated(true);
  };

  return (
    <Form noValidate validated={validated} onSubmit={handleSubmit}>
      <Form.Row>
        <Form.Group as={Col} md="4" controlId="validationCustom01">

Form libraries and server-rendered styles

It's often beneficial (especially in React) to handle form validation via a library like Formik, or react-formal. In those cases, isValid and isInvalid props can be added to form controls to manually apply validation styles. Below is a quick example integrating with Formik.

const { Formik } = formik;

const schema = yup.object().shape({
  firstName: yup.string().required(),
  lastName: yup.string().required(),
  username: yup.string().required(),
  city: yup.string().required(),
  state: yup.string().required(),
  zip: yup.string().required(),
  terms: yup.bool().required().oneOf([true], 'Terms must be accepted'),
});

function FormExample() {
  return (
    <Formik
      validationSchema={schema}
      onSubmit={console.log}
      initialValues={{
        firstName: 'Mark',
        lastName: 'Otto',
        username: '',
        city: '',
        state: '',
        zip: '',
        terms: false,
      }}
    >
      {({
        handleSubmit,
        handleChange,
        handleBlur,
        values,
        touched,
        isValid,
        errors,
      }) => (
        <Form noValidate onSubmit={handleSubmit}>
          <Form.Row>
            <Form.Group as={Col} md="4" controlId="validationFormik01">
              <Form.Label>First name</Form.Label>
              <Form.Control
                type="text"
                name="firstName"
                value={values.firstName}
                onChange={handleChange}
                isValid={touched.firstName && !errors.firstName}
              />
              <Form.Control.Feedback>Looks good!</Form.Control.Feedback>
            </Form.Group>
            <Form.Group as={Col} md="4" controlId="validationFormik02">

                onChange={handleChange}
                isValid={touched.lastName && !errors.lastName}
              />

              <Form.Control.Feedback>Looks good!</Form.Control.Feedback>
            </Form.Group>
            <Form.Group as={Col} md="4" controlId="validationFormikUsername">

Tooltips

If your form layout allows it, you can use the tooltip prop to display validation feedback in a styled tooltip. Be sure to have a parent with position: relative on it for tooltip positioning. In the example below, our column classes have this already, but your project may require an alternative setup.

const { Formik } = formik;

const schema = yup.object().shape({
  firstName: yup.string().required(),
  lastName: yup.string().required(),
  username: yup.string().required(),
  city: yup.string().required(),
  state: yup.string().required(),
  zip: yup.string().required(),
  file: yup.mixed().required(),
  terms: yup.bool().required().oneOf([true], 'terms must be accepted'),
});

function FormExample() {
  return (
    <Formik
      validationSchema={schema}
      onSubmit={console.log}
      initialValues={{
        firstName: 'Mark',
        lastName: 'Otto',
        username: '',
        city: '',
        state: '',
        zip: '',
        file: null,
        terms: false,
      }}
    >
      {({

        handleBlur,
        values,
        touched,

        errors,

Input group validation

To properly show rounded corners in an <InputGroup> with validation, the <InputGroup> requires the hasValidation prop.

Please choose a username.

<InputGroup hasValidation>
  <InputGroup.Prepend>
    <InputGroup.Text>@</InputGroup.Text>
  </InputGroup.Prepend>
  <Form.Control type="text" required isInvalid />
  <Form.Control.Feedback type="invalid">
    Please choose a username.
  </Form.Control.Feedback>
</InputGroup>

<InputGroup hasValidation>
  <InputGroup.Prepend>
    <InputGroup.Text>@</InputGroup.Text>
  </InputGroup.Prepend>
  <Form.Control type="text" required isInvalid />
  <Form.Control.Feedback type="invalid">
    Please choose a username.
  </Form.Control.Feedback>
</InputGroup>

Examples

Custom forms

For even more customization and cross browser consistency, use our completely custom form elements to replace the browser defaults. They’re built on top of semantic and accessible markup, so they’re solid replacements for any default form control.

Checkboxes and radios

Custom checkbox and radio styles are achieved with a resourceful use of the :checked selector and :after pseudo elements, but are Structurally similar to the default FormCheck. By default the checked and indeterminate icons use embedded svg icons from Open Iconic.

Apply Bootstrap's custom elements by adding the custom prop.

<Form>
  {['checkbox', 'radio'].map((type) => (
    <div key={`custom-${type}`} className="mb-3">
      <Form.Check 
        custom
        type={type}
        id={`custom-${type}`}
        label={`Check this custom ${type}`}
      />

      <Form.Check
        custom
        disabled
        type={type}
        label={`disabled ${type}`}
        id={`disabled-custom-${type}`}
      />
    </div>
  ))}
</Form>

<Form>
  {['checkbox', 'radio'].map((type) => (
    <div key={`custom-${type}`} className="mb-3">
      <Form.Check 
        custom
        type={type}
        id={`custom-${type}`}
        label={`Check this custom ${type}`}
      />
      <Form.Check
        custom
        disabled
        type={type}
        label={`disabled ${type}`}
        id={`disabled-custom-${type}`}
      />
    </div>
  ))}
</Form>

Switches

A switch has the markup of a custom checkbox but uses type="switch" to render a toggle switch. Switches also support the same customizable children as <FormCheck>.

<Form>
  <Form.Check 
    type="switch"
    id="custom-switch"
    label="Check this switch"
  />
  <Form.Check 
    disabled
    type="switch"
    label="disabled switch"
    id="disabled-custom-switch"
  />
</Form>

<Form>
  <Form.Check 
    type="switch"
    id="custom-switch"
    label="Check this switch"
  />
  <Form.Check 
    disabled
    type="switch"
    label="disabled switch"
    id="disabled-custom-switch"
  />
</Form>

Inline

<Form>
  {['checkbox', 'radio'].map((type) => (
    <div key={`custom-inline-${type}`} className="mb-3">
      <Form.Check
        custom
        inline
        label="1"
        type={type}
        id={`custom-inline-${type}-1`}
      />
      <Form.Check
        custom
        inline
        label="2"
        type={type}
        id={`custom-inline-${type}-2`}
      />
      <Form.Check
        custom
        inline
        disabled
        label="3 (disabled)"
        type={type}
        id={`custom-inline-${type}-3`}
      />
    </div>
  ))}
</Form>

<Form>
  {['checkbox', 'radio'].map((type) => (
    <div key={`custom-inline-${type}`} className="mb-3">
      <Form.Check
        custom
        inline
        label="1"
        type={type}
        id={`custom-inline-${type}-1`}
      />
      <Form.Check
        custom
        inline
        label="2"
        type={type}
        id={`custom-inline-${type}-2`}
      />
      <Form.Check
        custom
        inline
        disabled
        label="3 (disabled)"
        type={type}
        id={`custom-inline-${type}-3`}
      />
    </div>
  ))}
</Form>

Select

For the select form control you can pass the custom prop to get custom styling of the select element. Custom styles are limited to the select initial appearance and cannot modify the option styling due to browser limitations.

<Form>
  <Form.Group controlId="exampleForm.SelectCustom">
    <Form.Label>Custom select</Form.Label>
    <Form.Control as="select" custom>
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
</Form>

<Form>
  <Form.Group controlId="exampleForm.SelectCustom">
    <Form.Label>Custom select</Form.Label>
    <Form.Control as="select" custom>
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
</Form>

Sizing

The custom select element supports sizing.

<Form>
  <Form.Group controlId="exampleForm.SelectCustomSizeSm">
    <Form.Label>Custom select Small</Form.Label>
    <Form.Control as="select" size="sm" custom>
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
  <Form.Group controlId="exampleForm.SelectCustomSizeLg">
    <Form.Label>Custom select Large</Form.Label>
    <Form.Control as="select" size="lg" custom>
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
</Form>

<Form>
  <Form.Group controlId="exampleForm.SelectCustomSizeSm">
    <Form.Label>Custom select Small</Form.Label>
    <Form.Control as="select" size="sm" custom>
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
  <Form.Group controlId="exampleForm.SelectCustomSizeLg">
    <Form.Label>Custom select Large</Form.Label>
    <Form.Control as="select" size="lg" custom>
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
</Form>

HTML size

You can also specify the visible options of your select element.

<Form>
  <Form.Group controlId="exampleForm.SelectCustomHtmlSize">
    <Form.Label>Select with three visible options</Form.Label>
    <Form.Control as="select" htmlSize={3} custom>
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
</Form>

<Form>
  <Form.Group controlId="exampleForm.SelectCustomHtmlSize">
    <Form.Label>Select with three visible options</Form.Label>
    <Form.Control as="select" htmlSize={3} custom>
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </Form.Control>
  </Form.Group>
</Form>

Range

For the range form control you can pass the custom prop to get custom styling of the select element. The track (the background) and thumb (the value) are both styled to appear the same across browsers. As only IE and Firefox support “filling” their track from the left or right of the thumb as a means to visually indicate progress, we do not currently support it.

<Form>
  <Form.Group controlId="formBasicRangeCustom">
    <Form.Label>Range</Form.Label>
    <Form.Control type="range" custom />
  </Form.Group>
</Form>

<Form>
  <Form.Group controlId="formBasicRangeCustom">
    <Form.Label>Range</Form.Label>
    <Form.Control type="range" custom />
  </Form.Group>
</Form>

File

A custom styled File uploader.

<Form>
  <Form.File 
    id="custom-file"
    label="Custom file input"
    custom
  />
</Form>

<Form>
  <Form.File 
    id="custom-file"
    label="Custom file input"
    custom
  />
</Form>

Translating or customizing the strings with HTML

Bootstrap also provides a way to translate the “Browse” text in HTML with the data-browse attribute which can be added to the custom input label (example in Dutch):

<Form>
  <Form.File 
    id="custom-file-translate-html"
    label="Voeg je document toe"
    data-browse="Bestand kiezen"
    custom
  />
</Form>

<Form>
  <Form.File 
    id="custom-file-translate-html"
    label="Voeg je document toe"
    data-browse="Bestand kiezen"
    custom
  />
</Form>

Translating or customizing the strings with SCSS

Please refer to the official Bootstrap documentation for translating via SCSS. The lang prop can be used to pass the language.

<Form>
  <Form.File 
    id="custom-file-translate-scss"
    label="Custom file input"
    lang="en"
    custom
  />
</Form>

<Form>
  <Form.File 
    id="custom-file-translate-scss"
    label="Custom file input"
    lang="en"
    custom
  />
</Form>

Customizing FormFile rendering

When you need tighter control, or want to customize how the FormFile component renders, it may be better to use it's constituent parts directly.

By providing children to the FormFile you can forgo the default rendering and handle it yourself. (You can still provide an id to the FormFile and have it propagate to the label and input).

<Form>
  <div className="mb-3">
    <Form.File id="formcheck-api-custom" custom>
      <Form.File.Input isValid />
      <Form.File.Label data-browse="Button text">
        Custom file input
      </Form.File.Label>
      <Form.Control.Feedback type="valid">You did it!</Form.Control.Feedback>
    </Form.File>
  </div>
