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.
When using tooltips or popovers on elements within a .btn-group
, 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).
role
and provide a labelIn 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"
.
One exception are groups which only contain a single control (for instance the justified button groups with <button>
elements) or a dropdown.
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.
Wrap a series of buttons with .btn
in .btn-group
.
Combine sets of <div class="btn-group">
into a <div class="btn-toolbar">
for more complex components.
Instead of applying button sizing classes to every button in a group, just add .btn-group-*
to each .btn-group
, including when nesting multiple groups.
Place a .btn-group
within another .btn-group
when you want dropdown menus mixed with a series of buttons.
Make a set of buttons appear vertically stacked rather than horizontally. Split button dropdowns are not supported here.
Make a group of buttons stretch at equal sizes to span the entire width of its parent. Also works with button dropdowns within the button group.
Due to the specific HTML and CSS used to justify buttons (namely display: table-cell
), the borders between them are doubled. In regular button groups, margin-left: -1px
is used to stack the borders instead of removing them. However, margin
doesn't work with display: table-cell
. As a result, depending on your customizations to Bootstrap, you may wish to remove or re-color the borders.
Internet Explorer 8 doesn't render borders on buttons in a justified button group, whether it's on <a>
or <button>
elements. To get around that, wrap each button in another .btn-group
.
See #12476 for more information.
<a>
elementsJust wrap a series of .btn
s in .btn-group.btn-group-justified
.
If the <a>
elements are used to act as buttons – triggering in-page functionality, rather than navigating to another document or section within the current page – they should also be given an appropriate role="button"
.
<button>
elementsTo use justified button groups with <button>
elements, you must wrap each button in a button group. Most browsers don't properly apply our CSS for justification to <button>
elements, but since we support button dropdowns, we can work around that.
