This sample demonstrates the Scrollable option in the Menu component. Click the scroll arrows to view the hidden menu items.
The menu component supports horizontal and vertical scrolling to render large menus and submenus in an adaptive way. This can be achieved by enabling the enableScrolling property and by restricting the corresponding menu/submenu size.
In this demo, the parent menu is horizontally scrollable while the submenu and nested submenu are vertically scrollable.
More information about menu can be found in this documentation section.
