## Basic example

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 code={`<div class="input-group mb-3">
    <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 mb-3">
    <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 class="mb-3">
    <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 mb-3">
    <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>`} />

## 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`.

<Example code={`<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.

<Example code={`<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.**

<Example code={`<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.

<Example code={`<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>`.

<Example code={`<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.

<Example code={`<div class="input-group mb-3">
    <span class="input-group-text">$</span>
    <span class="input-group-text">0.00</span>
    <input type="text" class="form-control" aria-label="Dollar amount (with dot and two decimal places)">
  </div>

  <div class="input-group">
    <input type="text" class="form-control" aria-label="Dollar amount (with dot and two decimal places)">
    <span class="input-group-text">$</span>
    <span class="input-group-text">0.00</span>
  </div>`} />

## Button addons

<Example code={`<div class="input-group mb-3">
    <button class="btn btn-outline-secondary" type="button" id="button-addon1">Button</button>
    <input type="text" class="form-control" placeholder="" aria-label="Example text with button addon" aria-describedby="button-addon1">
  </div>

  <div class="input-group mb-3">
    <input type="text" class="form-control" placeholder="Recipient’s username" aria-label="Recipient’s username" aria-describedby="button-addon2">
    <button class="btn btn-outline-secondary" type="button" id="button-addon2">Button</button>
  </div>

  <div class="input-group mb-3">
    <button class="btn btn-outline-secondary" type="button">Button</button>
    <button class="btn btn-outline-secondary" type="button">Button</button>
    <input type="text" class="form-control" placeholder="" aria-label="Example text with two button addons">
  </div>

  <div class="input-group">
    <input type="text" class="form-control" placeholder="Recipient’s username" aria-label="Recipient’s username with two button addons">
    <button class="btn btn-outline-secondary" type="button">Button</button>
    <button class="btn btn-outline-secondary" type="button">Button</button>
  </div>`} />

## Buttons with dropdowns

<Example code={`<div class="input-group mb-3">
    <button class="btn btn-outline-secondary dropdown-toggle" type="button" data-bs-toggle="dropdown" aria-expanded="false">Dropdown</button>
    <ul class="dropdown-menu">
      <li><a class="dropdown-item" href="#">Action</a></li>
      <li><a class="dropdown-item" href="#">Another action</a></li>
      <li><a class="dropdown-item" href="#">Something else here</a></li>
      <li><hr class="dropdown-divider"></li>
      <li><a class="dropdown-item" href="#">Separated link</a></li>
    </ul>
    <input type="text" class="form-control" aria-label="Text input with dropdown button">
  </div>

  <div class="input-group mb-3">
    <input type="text" class="form-control" aria-label="Text input with dropdown button">

      <li><a class="dropdown-item" href="#">Something else here</a></li>
      <li><hr class="dropdown-divider"></li>
      <li><a class="dropdown-item" href="#">Separated link</a></li>
    </ul>
  </div>

  <div class="input-group">
    <button class="btn btn-outline-secondary dropdown-toggle" type="button" data-bs-toggle="dropdown" aria-expanded="false">Dropdown</button>
    <ul class="dropdown-menu">
      <li><a class="dropdown-item" href="#">Action before</a></li>
      <li><a class="dropdown-item" href="#">Another action before</a></li>
      <li><a class="dropdown-item" href="#">Something else here</a></li>
      <li><hr class="dropdown-divider"></li>
      <li><a class="dropdown-item" href="#">Separated link</a></li>
    </ul>
    <input type="text" class="form-control" aria-label="Text input with 2 dropdown buttons">
    <button class="btn btn-outline-secondary dropdown-toggle" type="button" data-bs-toggle="dropdown" aria-expanded="false">Dropdown</button>
    <ul class="dropdown-menu dropdown-menu-end">
      <li><a class="dropdown-item" href="#">Action</a></li>
      <li><a class="dropdown-item" href="#">Another action</a></li>

      <li><hr class="dropdown-divider"></li>
      <li><a class="dropdown-item" href="#">Separated link</a></li>
    </ul>
  </div>`} />

## Segmented buttons

<Example code={`<div class="input-group mb-3">
    <button type="button" class="btn btn-outline-secondary">Action</button>
    <button type="button" class="btn btn-outline-secondary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
      <span class="visually-hidden">Toggle Dropdown</span>
    </button>
    <ul class="dropdown-menu">
      <li><a class="dropdown-item" href="#">Action</a></li>

    </ul>
    <input type="text" class="form-control" aria-label="Text input with segmented dropdown button">
  </div>

  <div class="input-group">
    <input type="text" class="form-control" aria-label="Text input with segmented dropdown button">
    <button type="button" class="btn btn-outline-secondary">Action</button>
    <button type="button" class="btn btn-outline-secondary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
      <span class="visually-hidden">Toggle Dropdown</span>
    </button>
    <ul class="dropdown-menu dropdown-menu-end">
      <li><a class="dropdown-item" href="#">Action</a></li>
      <li><a class="dropdown-item" href="#">Another action</a></li>
      <li><a class="dropdown-item" href="#">Something else here</a></li>
      <li><hr class="dropdown-divider"></li>
      <li><a class="dropdown-item" href="#">Separated link</a></li>

  </div>`} />

## Custom forms

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

### Custom select

<Example code={`<div class="input-group mb-3">
    <label class="input-group-text" for="inputGroupSelect01">Options</label>
    <select class="form-select" id="inputGroupSelect01">
      <option selected>Choose...</option>
      <option value="1">One</option>
      <option value="2">Two</option>
      <option value="3">Three</option>
