You can display multiple menu levels in the static menu by setting the StaticDisplayLevels property to a value greater than 1. You can also display additional levels in dynamic menus by setting this property to a value greater than 0. For example, if you display two menu levels in the static menu (by setting the StaticDisplayLevels property to 2) and then set this property to 3, three additional menu levels are displayed in dynamic menus. All remaining higher menu levels (if any) are discarded.
Setting this property to 0 displays a flat menu up to the level specified by the StaticDisplayLevels property, without any dynamic menus.
