## 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]({{< docsref "/components/buttons#button-plugin" >}}).
{{< example >}}
{{< /example >}}
{{< callout warning >}}
##### 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.
{{< /callout >}}
## 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 >}}
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.

## 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 >}}

{{< /highlight >}}
## Nesting
Place a `.btn-group` within another `.btn-group` when you want dropdown menus mixed with a series of buttons.

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