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>
                <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" 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>
            
          

Sizing

Add the relative form sizing classes to the .input-group itself and contents within will automatically resizeā€”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
            
              <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="Small" 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="Default" 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="Large" aria-describedby="inputGroup-sizing-sm" />
              </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>
            
          

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">
                <div class="input-group-prepend">
                  <span class="input-group-text">First and last name</span>
                </div>
                <input type="text" class="form-control" />
                <input type="text" class="form-control" />
              </div>
            
          

Multiple addons

Multiple add-ons are supported and can be mixed with checkbox and radio input versions.

Input groups include support for custom selects and custom file inputs. Browser default versions of these are not supported.

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.
