Use case scenarios in EJ2 TypeScript 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.
import { Menu, MenuItemModel, BeforeOpenCloseMenuEventArgs, MenuModel } from '@syncfusion/ej2-navigations';
import { enableRipple, closest } from '@syncfusion/ej2-base';
enableRipple(true);
// Menu items definition
let menuItems: MenuItemModel[] = [

The following example demonstrates how to integrate Menu with Toolbar component.
import { Toolbar, Menu, MenuItemModel } from '@syncfusion/ej2-navigations';
let menuTemplate: string = '<ul id="menu"></ul>';
//Initialize Toolbar component
let toolbarObj: Toolbar = new Toolbar({
created: create,
items: [
{ template: menuTemplate },
{ prefixIcon: 'em-icons e-shopping-cart', align: 'Right' }
]
});
//Render initialized Toolbar component
toolbarObj.appendTo('#shoppingtoolbar');
function create(): void {
let data: { [key: string]: Object }[] = [
{
header: 'Events',
subItems: [
{ text: 'Conferences' },
{ text: 'Music' },
{ text: 'Workshops' }
]
},
{
header: 'Movies',
subItems: [
{ text: 'Now Showing' },
{ text: 'Coming Soon' }
]
},
{
header: 'Directory',
subItems: [
{ text: 'Media Gallery' },
{ text: 'Newsletters' }
]
},
{
header: 'Queries',
subItems: [
{ text: 'Our Policy' },
{ text: 'Site Map'},
{ text: '24x7 Support'}
]
},
{ header: 'Services' }
];
//Menu fields definition
let menuFields: Object = {
text: ['header', 'text', 'value'],
children: ['subItems', 'options']
};
//Initialize Menu component
let menuObj: Menu = new Menu({
items: data,
fields: menuFields,
animationSettings: { effect: 'None' }
}, '#menu');
this.refreshOverflow();
