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.
We do not support multiple form-controls in a single input group and
<label>s must come outside the input group.
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text" id="basic-addon1">@</span>
</div>
<input class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1" type="text">
</div>
<div class="input-group mb-3">
<input class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2"
type="text">
<div class="input-group-append">
<span class="input-group-text" id="basic-addon2">@example.com</span>
</div>
</div>
<label for="basic-url">Your vanity URL</label>
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text" id="basic-addon3">https://example.com/users/</span>
</div>
<input class="form-control" id="basic-url" aria-describedby="basic-addon3" type="text">
</div>
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text">$</span>
</div>
<input class="form-control" aria-label="Amount (to the nearest dollar)" type="text">
<div class="input-group-append">
<span class="input-group-text">.00</span>
</div>
</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.
<div class="input-group input-group-sm mb-3">
<div class="input-group-prepend">
<span class="input-group-text" id="inputGroup-sizing-sm">Small</span>
</div>
<input class="form-control" aria-label="Small" aria-describedby="inputGroup-sizing-sm" type="text">
</div>
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text" id="inputGroup-sizing-default">Default</span>
</div>
<input class="form-control" aria-label="Default" aria-describedby="inputGroup-sizing-default" type="text">
</div>
<div class="input-group input-group-lg">
<div class="input-group-prepend">
<span class="input-group-text" id="inputGroup-sizing-lg">Large</span>
</div>
<input class="form-control" aria-label="Large" aria-describedby="inputGroup-sizing-sm" type="text">
</div>
Checkboxes and radios
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-prepend">
<div class="input-group-text">
<input aria-label="Checkbox for following text input" type="checkbox">
</div>
</div>
<input class="form-control" aria-label="Text input with checkbox" type="text">
</div>
<div class="input-group">
<div class="input-group-prepend">
<div class="input-group-text">
<input aria-label="Radio button for following text input" type="radio">
</div>
</div>
<input class="form-control" aria-label="Text input with radio button" type="text">
</div>
While multiple
<input>s are supported visually, validation styles are only available for input groups with a single
<input>.
<div class="input-group">
<div class="input-group-prepend">
<span class="input-group-text">First and last name</span>
</div>
<input class="form-control" type="text">
<input class="form-control" type="text">
</div>
Multiple addons
Multiple add-ons are supported and can be mixed with checkbox and radio input versions.
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text">$</span>
<span class="input-group-text">0.00</span>
</div>
<input class="form-control" aria-label="Amount (to the nearest dollar)" type="text">
</div>
<div class="input-group">
<input class="form-control" aria-label="Amount (to the nearest dollar)" type="text">
<div class="input-group-append">
<span class="input-group-text">$</span>
<span class="input-group-text">0.00</span>

Accessibility
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.
