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.

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

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

<input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">

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

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

</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.
@
<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.

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

<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.
<div class="input-group mb-3">
<div class="input-group-text">
<input class="form-check-input" type="checkbox" value="" aria-label="Checkbox for following text input">

<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" 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
<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.
