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.

html

  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>
  6. <div class="input-group mb-3">
  7.   <input type="text" class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
  8.   <span class="input-group-text" id="basic-addon2">@example.com</span>
  9. </div>
  11. <label for="basic-url" class="form-label">Your vanity URL</label>
  12. <div class="input-group mb-3">
  13.   <span class="input-group-text" id="basic-addon3">https://example.com/users/</span>
  14.   <input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
  15. </div>
  17. <div class="input-group mb-3">
  18.   <span class="input-group-text">$</span>
  19.   <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
  20.   <span class="input-group-text">.00</span>
  21. </div>
  23. <div class="input-group mb-3">
  24.   <input type="text" class="form-control" placeholder="Username" aria-label="Username">
  25.   <span class="input-group-text">@</span>
  26.   <input type="text" class="form-control" placeholder="Server" aria-label="Server">
  27. </div>
  29. <div class="input-group">
  30.   <span class="input-group-text">With textarea</span>
  31.   <textarea class="form-control" aria-label="With textarea"></textarea>
  32. </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.

html

  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.

html

  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>

Checkboxes and radios

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.

html

  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>.

  1. <div class="input-group">

  3.   <input type="text" aria-label="First name" class="form-control">
  4.   <input type="text" aria-label="Last name" class="form-control">
  5. </div>

Multiple addons

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