Easily extend form controls by adding text, buttons, or button groups on either side of textual inputs, custom selects, and custom file inputs.
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.
<div class="input-group mb-3">
<span class="input-group-text btn-primary" 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 btn-primary" 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 btn-primary" 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 btn-primary">$</span>
<input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
<span class="input-group-text btn-primary">.00</span>
</div>
<div class="input-group">
<span class="input-group-text btn-primary">With textarea</span>
<textarea class="form-control" aria-label="With textarea"></textarea>
</div>
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.
<div class="input-group flex-nowrap">
<span class="input-group-text btn-primary" id="addon-wrapping">@</span>
<input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="addon-wrapping">
</div>
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.
<div class="input-group input-group-sm mb-3">
<span class="input-group-text btn-primary" 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 btn-primary" 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 btn-primary" id="inputGroup-sizing-lg">Large</span>
<input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-lg">
</div>
Place any checkbox or radio option within an input group’s addon instead of text.
<div class="input-group mb-3">
<div class="input-group-text btn-primary">
<input class="form-check-input" 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 btn-primary">
<input class="form-check-input" 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>
While multiple <input>s are supported visually, validation styles are only available for input groups with a single <input>.
<div class="input-group">
<span class="input-group-text btn-primary">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>
<div class="input-group mb-3">
<button class="btn btn-outline-primary" type="button" id="button-addon1">Button</button>

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

Input groups include support for custom selects and custom file inputs. Browser default versions of these are not supported.
<div class="input-group mb-3">

Screen readers will have trouble with your forms if you don’t include a label for every input. For these input groups, ensure that any additional label or functionality is conveyed to assistive technologies.
The exact technique to be used (<label> elements hidden using the .sr-only class, or use of the aria-label and aria-labelledby attributes, possibly in combination with aria-describedby) and what additional information will need to be conveyed will vary depending on the exact type of interface widget you’re implementing. The examples in this section provide a few suggested, case-specific approaches.
