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.

Input group - 图1

  1. <div class="input-group mb-3">
  2. <span class="input-group-text" id="basic-addon1">@</span>
  3. <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
  4. </div>
  5. <div class="input-group mb-3">
  6. <input type="text" class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
  7. <span class="input-group-text" id="basic-addon2">@example.com</span>
  8. </div>
  9. <label for="basic-url" class="form-label">Your vanity URL</label>
  10. <div class="input-group mb-3">
  11. <span class="input-group-text" id="basic-addon3">https://example.com/users/</span>
  12. <input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
  13. </div>
  14. <div class="input-group mb-3">
  15. <span class="input-group-text">$</span>
  16. <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
  17. <span class="input-group-text">.00</span>
  18. </div>
  19. <div class="input-group mb-3">
  20. <input type="text" class="form-control" placeholder="Username" aria-label="Username">
  21. <span class="input-group-text">@</span>
  22. <input type="text" class="form-control" placeholder="Server" aria-label="Server">
  23. </div>
  24. <div class="input-group">
  25. <span class="input-group-text">With textarea</span>
  26. <textarea class="form-control" aria-label="With textarea"></textarea>
  27. </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.

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.

Input group - 图3

  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>
  5. <div class="input-group mb-3">
  6. <span class="input-group-text" id="inputGroup-sizing-default">Default</span>
  7. <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-default">
  8. </div>
  9. <div class="input-group input-group-lg">

  11. <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-lg">
  12. </div>

Checkboxes and radios

Place any checkbox or radio option within an input group’s addon instead of text.

  10. </div>
  11. <input type="text" class="form-control" aria-label="Text input with radio button">
  12. </div>

Multiple inputs

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