React Menu - Scrolling

The DevExtreme Menu component supports submenu item scrolling. If combined item height exceeds screen size or a pre-defined height limit, a scrollbar appears on-screen.

You can use one of the following event handlers to configure submenus as requirements dictate:

These handlers can access the root submenu element (submenuContainer) and data from root and submenu items (itemData).

In this demo, the onSubmenuShowing function limits submenu height to 200px.
