Features

Tree Structure

The ASPxMenu control can contain the following menu items types:

root menu items - a menu item located at the menu’s top level (level 0).
child menu item - a menu item that has a parent menu item.

The menu stores its root items in the ASPxMenuBase.Items collection. Child menu items are stored in the parent menu item’s MenuItem.Items collection.

The submenu items appear and disappear when an end user clicks outside the menu or according to the ASPxMenuBase.AppearAfter and ASPxMenuBase.DisappearAfter settings.
