# 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.

## 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.com
Your vanity URL
https://example.com/users/
$ .00
@
With textarea
html

    <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>

    <label for="basic-url" class="form-label">Your vanity URL</label>
    <div class="input-group mb-3">
      <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">
    </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`.

@
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>

## 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.

      <span class="input-group-text">$</span>
