Examples

Two basic options, along with two more specific variations.

Single button group

Wrap a series of buttons with .btn in .btn-group.

<div class="btn-group">
  <button class="btn">Left</button>
  <button class="btn">Middle</button>
  <button class="btn">Right</button>
</div>

Multiple button groups

Combine sets of <div class="btn-group"> into a <div class="btn-toolbar"> for more complex components.

<div class="btn-toolbar">
  <div class="btn-group">
    ...
  </div>
</div>

Vertical button groups

Make a set of buttons appear vertically stacked rather than horizontally.

<div class="btn-group btn-group-vertical">
  ...
</div>
