--- layout: page title: 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](../javascript/#buttons).

Tooltips & popovers in button groups require special setting

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).

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.

### Basic example Wrap a series of buttons with `.btn` in `.btn-group`. {% example html %}
{% endexample %} ### Button toolbar Combine sets of button groups into button toolbars for more complex components. {% example html %} {% endexample %} ### 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.

{% endhighlight %} ### Nesting Place a `.btn-group` within another `.btn-group` when you want dropdown menus mixed with a series of buttons. {% example html %}
{% endexample %} ### Vertical variation Make a set of buttons appear vertically stacked rather than horizontally. **Split button dropdowns are not supported here.**
