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.
<div class= "input-group mb-3" >
<div class= "input-group-prepend" >
<span class= "input-group-text" id= "basic-addon1" > @</span>
</div>
<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" >
<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 type= "text" class= "form-control" id= "basic-url" aria-describedby= "basic-addon3" >
</div>
<div class= "input-group mb-3" >
<div class= "input-group-prepend" >
<span class= "input-group-text" > $</span>
</div>
<input type= "text" class= "form-control" aria-label= "Amount (to the nearest dollar)" >
<div class= "input-group-append" >
<span class= "input-group-text" > .00</span>
</div>
</div>
<div class= "input-group" >
<div class= "input-group-prepend" >
<span class= "input-group-text" > With textarea</span>
</div>
<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" >
<div class= "input-group-prepend" >
<span class= "input-group-text" id= "addon-wrapping" > @</span>
</div>
<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.
<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 type= "text" class= "form-control" aria-label= "Sizing example input" aria-describedby= "inputGroup-sizing-sm" >
</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 type= "text" class= "form-control" aria-label= "Sizing example input" aria-describedby= "inputGroup-sizing-default" >
</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 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-prepend" >
<div class= "input-group-text" >
<input type= "checkbox" aria-label= "Checkbox for following text input" >
</div>
</div>
<input type= "text" class= "form-control" aria-label= "Text input with checkbox" >
</div>
<div class= "input-group" >
<div class= "input-group-prepend" >
<div class= "input-group-text" >
<input type= "radio" aria-label= "Radio button for following text input" >
</div>
</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" >
<div class= "input-group-prepend" >
<span class= "input-group-text" > First and last name</span>
</div>
<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.
<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 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)" >
<div class= "input-group-append" >
<span class= "input-group-text" > $</span>
<span class= "input-group-text" > 0.00</span>
</div>
</div>

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.
