Use case scenarios in EJ2 JavaScript Menu control
2 May 202324 minutes to read
Scrollable menu
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.
ej.base.enableRipple(true);
var menuItems = [

text: 'Appliances',
items: [

//Initialize Menu component
var menuObj = new ej.navigations.Menu({
