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.
{% endcallout %}
Basic example
Wrap a series of buttons with .btn in .btn-group.
{% example html %}
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.
{% example html %}
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.
{% example html %}
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.
{% highlight html %}
Nesting
Place a .btn-group within another .btn-group when you want dropdown menus mixed with a series of buttons.
{% example html %}
Vertical variation
Make a set of buttons appear vertically stacked rather than horizontally. Split button dropdowns are not supported here.
{% highlight html %}
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).
