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.

Input group - 图2

  1. <div class="input-group flex-nowrap">
  2.   <span class="input-group-text" id="addon-wrapping">@</span>
  3.   <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="addon-wrapping">
  4. </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.

  1. <div class="input-group input-group-sm mb-3">
  2.   <span class="input-group-text" id="inputGroup-sizing-sm">Small</span>
  3.   <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-sm">
  4. </div>
  6. <div class="input-group mb-3">
  7.   <span class="input-group-text" id="inputGroup-sizing-default">Default</span>
  8.   <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-default">
  9. </div>
  11. <div class="input-group input-group-lg">
  12.   <span class="input-group-text" id="inputGroup-sizing-lg">Large</span>
  13.   <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-lg">
  14. </div>

Place any checkbox or radio option within an input group’s addon instead of text. We recommend adding .mt-0 to the .form-check-input when there’s no visible text next to the input.

  1. <div class="input-group mb-3">
  2.   <div class="input-group-text">
  3.     <input class="form-check-input mt-0" type="checkbox" value="" aria-label="Checkbox for following text input">
  4.   </div>
  5.   <input type="text" class="form-control" aria-label="Text input with checkbox">
  6. </div>
  8. <div class="input-group">
  9.   <div class="input-group-text">
  10.     <input class="form-check-input mt-0" type="radio" value="" aria-label="Radio button for following text input">
  11.   </div>
  12.   <input type="text" class="form-control" aria-label="Text input with radio button">
  13. </div>

Multiple inputs

While multiple <input>s are supported visually, validation styles are only available for input groups with a single <input>.

Multiple addons

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

  1. <div class="input-group mb-3">
  2.   <span class="input-group-text">$</span>
  3.   <span class="input-group-text">0.00</span>
  4.   <input type="text" class="form-control" aria-label="Dollar amount (with dot and two decimal places)">

Segmented buttons

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