When used with a GenericMenu, use [Dropdown](/engine/6000.0/script-reference/unityeditor/genericmenu/dropdown.md) and pass the same rect to the method as was used for the button position.

When used with a custom EditorWindow, use ShowAsDropdown and pass the same rect to the method as was used for the button position.
