Overview

Be sure to use an appropriate type attribute on all inputs (e.g., email for email address or number for numerical information) to take advantage of newer input controls like email verification, number selection, and more.

Here's a quick example to demonstrate Bootstrap's form styles. Keep reading for documentation on required classes, form layout, and more.

We'll never share your email with anyone else.

<template>
  <BForm>
    <BFormControl margin="b-3">

<script setup>
const email = ref('email')
const password = ref('')
const checked = ref(false)
</script>

Form text

Block-level or inline-level form text can be created using FormText.

Form text below inputs can be styled with FormText.

If a block-level element will be used, a top margin is added for easy spacing from the inputs above.

Your password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji.
vue
<template>
  <BFormControl>
    <BFormLabel>Password</BFormLabel>
    <BFormInput
      type="password"
      aria-describedby="passwordHelpBlock"
    />
    <BFormText>
      Your password must be 8-20 characters long, contain letters and numbers,
      and must not contain spaces, special characters, or emoji.
    </BFormText>
  </BFormControl>
</template>

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

be 8-20 characters long.
vue
<template>
  <Row
    gutter="3"
    align-items="center"
  >
    <Col col="auto">
      <BColFormLabel for="inputPassword6">
        Password
      </BColFormLabel>
    </Col>
    <Col col="auto">
      <BFormInput
        id="inputPassword6"
        type="password"
        aria-describedby="passwordHelpInline"
      />
    </Col>
    <Col col="auto">
      <b-span>
        <BFormText>be 8-20 characters long.</BFormText>
      </b-span>
    </Col>
  </Row>
</template>

Disabled forms

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

vue
<template>
  <BFormInput
    type="text"
    placeholder="Disabled input here..."
    disabled
  />
</template>

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

Browsers treat all native form controls (FormInput, FormSelect, and Button elements) inside a` <fieldset disabled>as disabled, preventing both keyboard and mouse interactions on them.

However, if your form also includes custom button-like elements such as <a class="btn btn-*"></a>, these will only be given a style of pointer-events: none, meaning they are still focusable and operable using the keyboard.

In this case, you must manually modify these controls by adding tabindex="-1" to prevent them from receiving focus and aria-disabled="disabled" to signal their state to assistive technologies.

Disabled fieldset example
vue
<template>
  <BForm>
    <BFieldset disabled>
      <BLegend>Disabled fieldset example</BLegend>
      <BFormControl margin="b-3">
        <BFormLabel>Disabled input</BFormLabel>
        <BFormInput
          type="text"
          placeholder="Disabled input"
        />
      </BFormControl>
      <BFormControl margin="b-3">
        <BFormLabel>Disabled select menu</BFormLabel>
        <BFormSelect>
          <option>Disabled select</option>
        </BFormSelect>
      </BFormControl>
      <BFormControl margin="b-3">
        <BFormCheck>
          <BFormCheckInput
            type="checkbox"
            disabled
          />
          <BFormCheckLabel>Can't check this</BFormCheckLabel>
        </BFormCheck>
      </BFormControl>
      <b-button
        type="submit"
        button="primary"
      >
        Submit
      </b-button>
    </BFieldset>
