Input group

Easily extend form controls by adding text, buttons, or button groups on either side of textual inputs, custom selects, and custom file inputs.

Examples

Place one add-on or button on either side of an input. You may also place one on both sides of an input. Remember to place <label>s outside the input group.

@
@example.com
https://example.com/users/
Example help text goes outside the input group.

With textarea
HTML
<div class="input-group">
  <span class="input-group-text" id="basic-addon1">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
</div>

<div class="input-group">
  <input type="text" class="form-control" placeholder="Recipient’s username" aria-label="Recipient’s username" aria-describedby="basic-addon2">
  <span class="input-group-text" id="basic-addon2">@example.com</span>
</div>

<div>
  <label for="basic-url" class="form-label">Your vanity URL</label>
  <div class="input-group">
    <span class="input-group-text" id="basic-addon3">https://example.com/users/</span>
    <input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3 basic-addon4">
  </div>
  <div class="form-text" id="basic-addon4">Example help text goes outside the input group.</div>
</div>

<div class="input-group">
  <span class="input-group-text">$</span>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
  <span class="input-group-text">.00</span>
</div>

<div class="input-group mb-3">
    <input type="text" class="form-control" placeholder="Username" aria-label="Username">
  <span class="input-group-text">@</span>
  <input type="text" class="form-control" placeholder="Server" aria-label="Server">
</div>

<div class="input-group">
  <span class="input-group-text">With textarea</span>
  <textarea class="form-control" aria-label="With textarea"></textarea>
</div>

<div class="input-group">
  <button class="btn-outline theme-secondary input-group-btn" type="button" id="button-addon">Button</button>
  <input type="text" class="form-control" placeholder="" aria-label="Example text with button addon" aria-describedby="button-addon">
</div>

Wrapping

Input groups wrap by default via flex-wrap: wrap in order to accommodate custom form field validation within an input group. You may disable this with .flex-nowrap.

@
HTML
<div class="input-group flex-nowrap">
  <span class="input-group-text" id="addon-wrapping">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="addon-wrapping">
</div>

Border radius

Due to limitations of browser support at the time, border-radius styles can only be applied to the first and last children within the .input-group class. Any non-visible element in one of those positions will cause the input group to render incorrectly. This will unfortunately not be fixed until v6 most likely.

@
HTML
<div class="input-group">
  <span class="input-group-text" id="visible-addon">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="visible-addon">
  <input type="text" class="form-control d-none" placeholder="Hidden input" aria-label="Hidden input" aria-describedby="visible-addon">
</div>

Sizing

Add the relative form sizing classes to the .input-group itself and contents within will automatically resize—no need for repeating the form control size classes on each element.

Sizing on the individual input group elements isn’t supported.

Small
Default
Large
HTML
<div class="input-group input-group-sm mb-3">
  <span class="input-group-text" id="inputGroup-sizing-sm">Small</span>
  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-sm">
</div>

<div class="input-group mb-3">
  <span class="input-group-text" id="inputGroup-sizing-default">Default</span>
  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-default">
</div>

<div class="input-group input-group-lg">
  <span class="input-group-text" id="inputGroup-sizing-lg">Large</span>
  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-lg">
</div>

Checkboxes and radios

Place any checkbox or radio option within an input group’s addon instead of text. We recommend adding .mt-0 to the .form-check-input when there’s no visible text next to the input.

HTML
<div class="input-group mb-3">
  <div class="input-group-text">
    <input class="form-check-input mt-0" type="checkbox" value="" aria-label="Checkbox for following text input">
  </div>
  <input type="text" class="form-control" aria-label="Text input with checkbox">
</div>

<div class="input-group">
  <div class="input-group-text">
    <input class="form-check-input mt-0" type="radio" value="" aria-label="Radio button for following text input">
  </div>
  <input type="text" class="form-control" aria-label="Text input with radio button">
</div>

Multiple inputs

While multiple <input>s are supported visually, validation styles are only available for input groups with a single <input>.

First and last name
HTML
<div class="input-group">
  <span class="input-group-text">First and last name</span>
  <input type="text" aria-label="First name" class="form-control">
  <input type="text" aria-label="Last name" class="form-control">
</div>

Multiple addons

Multiple add-ons are supported and can be mixed with checkbox and radio input versions.

Custom forms

Input groups include support for custom selects and custom file inputs. Browser default versions of these are not supported.

    <option value="3">Three</option>
  </select>
  <button class="btn-outline theme-secondary input-group-btn" type="button">Button</button>
</div>

Custom file input

HTML
<div class="input-group mb-3">
  <label class="input-group-text" for="inputGroupFile01">Upload</label>
  <input type="file" class="form-control" id="inputGroupFile01">
</div>

<div class="input-group mb-3">

  <button class="btn-outline theme-secondary input-group-btn" type="button" id="inputGroupFileAddon04">Button</button>
</div>

CSS

Variables

Input group addons use local CSS variables on .input-group-text for real-time customization. Values for the CSS variables are generated from Sass maps unique to each component and applied to the aforementioned class.

SCSS
// stylelint-disable-next-line scss/dollar-variable-default
$input-group-addon-tokens: defaults(
  (
    --input-group-addon-padding-y: var(--btn-input-padding-y),
    --input-group-addon-padding-x: var(--btn-input-padding-x),
    --input-group-addon-font-size: var(--btn-input-font-size),
    --input-group-addon-line-height: var(--btn-input-line-height),
    --input-group-addon-color: var(--fg-body),
    --input-group-addon-bg: var(--bg-2),
    --input-group-addon-border-color: var(--border-color),
  ),
  $input-group-addon-tokens
);

Sass list

We use a Sass list to define the sizes of the input group, so you can easily add or modify sizes by fetching the associated root variables for each size. This list should generally match the sizes defined in the $form-control-sizes Sass map in _form-control.scss.

SCSS
$input-group-sizes: ();
// stylelint-disable-next-line scss/dollar-variable-default
$input-group-sizes: defaults(
  ("sm", "lg"),
  $input-group-sizes
);
