Over a dozen reusable components built to provide buttons, dropdowns, input groups, navigation, alerts, and much more.

Button group

Group a series of buttons together on a single line with the button group. Add on optional JavaScript radio and checkbox style behavior with our buttons plugin.


Basic example

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

<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>

Button toolbar

Combine sets of button groups into button toolbars for more complex components.

<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
  <div class="btn-group" 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 class="btn-group" 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 class="btn-group" role="group" aria-label="Third group">
    <button type="button" class="btn btn-secondary">8</button>


Instead of applying button sizing classes to every button in a group, just add .btn-group-* to each .btn-group, including each one when nesting multiple groups.

<div class="btn-group btn-group-lg" role="group" aria-label="...">...</div>
<div class="btn-group" role="group" aria-label="...">...</div>
<div class="btn-group btn-group-sm" role="group" aria-label="...">...</div>


Place a .btn-group within another .btn-group when you want dropdown menus mixed with a series of buttons.

<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">
    <div class="dropdown-menu" aria-labelledby="btnGroupDrop1">
      <a class="dropdown-item" href="#">Dropdown link</a>
      <a class="dropdown-item" href="#">Dropdown link</a>

Vertical variation

Make a set of buttons appear vertically stacked rather than horizontally. Split button dropdowns are not supported here.

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

Tooltips and popovers

Due to the specific implementation (and some other components), a bit of special casing is required for tooltips and popovers within button groups. You’ll have to specify the option container: 'body' to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).
