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

Basic example

Wrap a series of buttons with .btn in .btn-group. Add on optional JavaScript radio and checkbox style behavior with [our buttons plugin]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/buttons/#button-plugin).

{% capture example %}

{% endcapture %} {% include example.html content=example %}

{% capture callout %}

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. {% endcapture %} {% include callout.html content=callout type="warning" %}

Button toolbar

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

{% capture example %}

{% endcapture %} {% include example.html content=example %}

Feel free to mix input groups with button groups in your toolbars. Similar to the example above, you'll likely need some utilities though to space things properly.

{% capture example %}

{% endcapture %} {% include example.html content=example %}

Sizing

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.

Nesting

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

{% capture example %}

{% endcapture %} {% include example.html content=example %}

Vertical variation

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