	<description>
		OptionButton is a type button that provides a selectable list of items when pressed. The item selected becomes the "current" item and is displayed as the button text.
		See also [BaseButton] which contains common properties and methods associated with this node.
		[b]Note:[/b] The ID values used for items are limited to 32 bits, not full 64 bits of [int]. This has a range of [code]-2^32[/code] to [code]2^32 - 1[/code], i.e. [code]-2147483648[/code] to [code]2147483647[/code].
