SlideMenu

SlideMenu is a menu that can expand and collapse at the touch of a button. The SlideMenu can expand in any of the four directions. Menu items can be added, just like items are added to a normal container.

The relative positions of the background and state change button is configurable as is the direction in which the SlideMenu expands and collapses. How much of the SlideMenu that is visible when collapsed can also be set with the. It is, of course, important that the state change button is accessible when collapsed. The SlideMenu will collapse after a given timeout is reached. The timer can be reset, for example when the user interacts with elements in the list.

Menu elements are added normally using the add() method and are positioned relative to the SlideMenu.
