Button group
Group a series of buttons together on a single line or stack them in a vertical column.
Basic example
Wrap a series of buttons with .btn in .btn-group.
Button groups require an appropriate role attribute and explicit label to ensure assistive technologies like screen readers identify buttons as grouped and announce them. Use role="group" for button groups or role="toolbar" for button toolbars. Then use aria-label or aria-labelledby to label them.
These classes can also be added to groups of links, as an alternative to the .nav navigation components.
Mixed styles
Outlined styles
Checkbox and radio button groups
Combine button-like checkbox and radio toggle buttons into a seamless looking button group.
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.
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.
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.
