Button groups

Group a series of buttons together on a single line with the button group, and super-power them with JavaScript.

Wrap a series of buttons with .btn in a .button-group. Add radio and checkbox style behavior with Bootstrap’s buttons JavaScript plugin.


<div class="btn-group" role="group" aria-label="Basic example">
  <button type="button" class="btn btn-secondary">Left</button>
  <button type="button" class="btn btn-secondary">Middle</button>
  <button type="button" class="btn btn-secondary">Right</button>
</div>

Ensure correct role and provide a label

In order for assistive technologies (such as screen readers) to convey that a series of buttons is grouped, an appropriate role attribute needs to be provided. For button groups, this would be role="group", while toolbars should have a role="toolbar".

In addition, groups and toolbars should be given an explicit label, as most assistive technologies will otherwise not announce them, despite the presence of the correct role attribute. In the examples provided here, we use aria-label, but alternatives such as aria-labelledby can also be used.

Combine sets of button groups into button toolbars for more complex components. Use utility classes as needed to space out groups, buttons and more.


<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
  <div class="btn-group mr-2" role="group" aria-label="First group">
    <button type="button" class="btn btn-secondary">1</button>
    <button type="button" class="btn btn-secondary">2</button>
    <button type="button" class="btn btn-secondary">3</button>
    <button type="button" class="btn btn-secondary">4</button>
  </div>
  <div class="btn-group mr-2" role="group" aria-label="Second group">
    <button type="button" class="btn btn-secondary">5</button>
    <button type="button" class="btn btn-secondary">6</button>
    <button type="button" class="btn btn-secondary">7</button>
  </div>
  <div class="btn-group" role="group" aria-label="Third group">
    <button type="button" class="btn btn-secondary">8</button>
  </div>
</div>

Customizing button groups

Sizes

Make button groups larger or smaller using .btn-group-lg or .btn-group-sm respectively.


<div class="btn-group btn-group-lg" role="group" aria-label="Basic example">
  <button type="button" class="btn btn-secondary">Large</button>
  <button type="button" class="btn btn-secondary">button</button>
  <button type="button" class="btn btn-secondary">group</button>
</div>

<div class="btn-group" role="group" aria-label="Basic example">
  <button type="button" class="btn btn-secondary">Default</button>
  <button type="button" class="btn btn-secondary">button</button>
  <button type="button" class="btn btn-secondary">group</button>
</div>

<div class="btn-group btn-group-sm" role="group" aria-label="Basic example">
  <button type="button" class="btn btn-secondary">Small</button>
  <button type="button" class="btn btn-secondary">button</button>
  <button type="button" class="btn btn-secondary">group</button>
</div>

Nesting

Place a .btn-group within another .btn-group if you wish to place a dropdown menu in a button group.


<div class="btn-group" role="group" aria-label="Button group with nested dropdown">
  <button type="button" class="btn btn-secondary">1</button>
  <button type="button" class="btn btn-secondary">2</button>

  <div class="btn-group" role="group">
    <button id="btnGroupDrop1" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
      Dropdown
    </button>
    <div class="dropdown-menu" aria-labelledby="btnGroupDrop1">
      <a class="dropdown-item" href="#">Dropdown link</a>
      <a class="dropdown-item" href="#">Dropdown link</a>
    </div>
  </div>
</div>

Vertical orientation

Make a set of buttons appear vertically stacked rather than horizontally using .btn-group-vertical. Split button dropdowns are not supported here.


<div class="btn-group btn-group-vertical" role="group" aria-label="Button group with nested dropdown">
  <button type="button" class="btn btn-secondary">Button</button>
  <button type="button" class="btn btn-secondary">Button</button>

  <div class="btn-group" role="group">
    <button id="btnGroupDrop1" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
      Dropdown
    </button>
    <div class="dropdown-menu" aria-labelledby="btnGroupDrop1">
      <a class="dropdown-item" href="#">Dropdown link</a>
      <a class="dropdown-item" href="#">Dropdown link</a>
    </div>
  </div>
</div>
