Enable or disable context menu items in JavaScript ContextMenu control

You can enable and disable the menu items using the enableItems method in ContextMenu. To enable menuItems, set the enable property in argument to true and vice-versa.

In the following example, the Display Settings in parent items and Medium icons in sub menu items are disabled.

import { ContextMenu, MenuItemModel, ContextMenuModel, BeforeOpenCloseMenuEventArgs } from '@syncfusion/ej2-navigations';
import { enableRipple } from '@syncfusion/ej2-base';

//ContextMenu items definition
let menuItems: MenuItemModel[] = [
        text: 'View',
        items: [
            text: 'Large icons'
            text: 'Medium icons'
            text: 'Small icons'
        text: 'Sort By'
        text: 'Refresh'
        separator: true
        text: 'New'
        separator: true
        text: 'Display Settings'
        text: 'Personalize'

//ContextMenu model definition
let menuOptions: ContextMenuModel = {
    target: '#target',
    items: menuItems,
    beforeOpen: (args: BeforeOpenCloseMenuEventArgs) => {
      menuObj.enableItems(['Medium icons'], false);

let menuObj: ContextMenu = new ContextMenu(menuOptions, '#contextmenu');

menuObj.enableItems(['Display Settings'], false);
