Description
-----------

**OptionButton** is a type of button that brings up a dropdown with selectable items when pressed. The item selected becomes the "current" item and is displayed as the button text.

See also :ref:`BaseButton<class_BaseButton>` which contains common properties and methods associated with this node.

\ **Note:** The ID values used for items are limited to 32 bits, not full 64 bits of :ref:`int<class_int>`. This has a range of ``-2^32`` to ``2^32 - 1``, i.e. ``-2147483648`` to ``2147483647``.

\ **Note:** The :ref:`Button.text<class_Button_property_text>` and :ref:`Button.icon<class_Button_property_icon>` properties are set automatically based on the selected item. They shouldn't be changed manually.
