public static bool DropdownButton(Rect position, GUIContent content, FocusType focusType, GUIStyle style);

Parameters

positionRectangle on the screen to use for the button.
contentText, image and tooltip for this button.
focusTypeWhether the button should be selectable by keyboard or not.
styleOptional style to use.

Returns

bool true when the user clicks the button.

Description

Makes a button that reacts to mouse down, for displaying your own dropdown content.

This control does not do anything but returns true on mouse down when clicked, as opposed to regular buttons that return true on mouse up.

This can be used for buttons that should open a GenericMenu or your own custom EditorWindow in dropdown form.

When used with a GenericMenu, use GenericMenu.Dropdown and pass the same rect to the method as was used for the button position.

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