Menu
Populate Menu with Data and Configure the Access to It
You can display Menu items from the items array or a dataSource. This demo contains an example of a data structure. If you use a dataSource, specify the displayExpr property.
To access the clicked item, use the onItemClick event handler function.
Configure the Menu
Use the orientation property to specify whether the Menu has horizontal or vertical orientation. Use the animation property to specify the type, delay, duration, and other options of show and hide menu actions.
Configure the Submenus
Clicking or a hovering a Menu item opens a drop-down menu that can contain several submenus. To specify the drop-down menu mode ("onClick" or "onHover"), use the showSubmenuMode property. If you need only to specify the first level of drop-down menus, use the showFirstSubmenuMode property.
If you want to hide the submenu when the mouse pointer leaves it, set the hideSubmenuOnMouseLeave property to true.
Customize Item Appearance
You can define specific fields in the item data objects to change the appearance of an item. For example, use the icon property to supply items with icons. Define an itemTemplate to customize item appearance.
