+		A group of [BaseButton]-derived buttons. The buttons in a [ButtonGroup] are treated like radio buttons: No more than one button can be pressed at a time. Some types of buttons (such as [CheckBox]) may have a special appearance in this state.
+		Every member of a [ButtonGroup] should have [member BaseButton.toggle_mode] set to [code]true[/code].
