29 Aug 20237 minutes to read

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.

index.jsx

import { enableRipple } from '@syncfusion/ej2-base';
import { ContextMenuComponent } from '@syncfusion/ej2-react-navigations';
import * as React from 'react';
import * as ReactDom from 'react-dom';
enableRipple(true);
function App() {
    let cMenu;
    let menuItems = [
        {
            items: [
                { text: 'Large icons' },
                { text: 'Medium icons' },
                { text: 'Small icons' }
            ],
            text: 'View'
        },
        {
            text: 'Sort By'
        },
        {
            text: 'Refresh'
        },
        {
            separator: true
        },
        {
            text: 'New'
        },
        {
            separator: true
        },
        {
            text: 'Display Settings'
        },
        {
            text: 'Personalize'
        }
    ];
    return (<div className="container">
            <div id='target'>Right click / Touch hold to open the ContextMenu</div>
            <ContextMenuComponent id="cmenu" ref={(scope) => cMenu = scope} target='#target' items={menuItems} created={created} beforeOpen={beforeOpen}/>
        </div>);
    function created() {
        cMenu.enableItems(['Display Settings'], false);
    }
    ;
    function beforeOpen() {
        cMenu.enableItems(['Medium icons'], false);
    }
    ;
}
export default App;
ReactDom.render(<App />, document.getElementById('element'));

index.tsx

import { enableRipple } from '@syncfusion/ej2-base';
import { ContextMenuComponent, MenuItemModel } from '@syncfusion/ej2-react-navigations';
import * as React from 'react';
import * as ReactDom from 'react-dom';

enableRipple(true);

function App() {
    let cMenu: ContextMenuComponent;
    let menuItems: MenuItemModel[] = [
        {
            items: [
                { text: 'Large icons' },
                { text: 'Medium icons' },
                { text: 'Small icons' }
            ],
            text: 'View'
        },
        {
            text: 'Sort By'
        },
        {
            text: 'Refresh'
        },
        {
            separator: true
        },
        {
            text: 'New'
        },
        {
            separator: true
        },
        {
            text: 'Display Settings'
        },
        {
            text: 'Personalize'
        }
    ];

    return (
        <div className="container">
            <div id='target'>Right click / Touch hold to open the ContextMenu</div>
            <ContextMenuComponent id="cmenu" ref={(scope) => cMenu = scope as ContextMenuComponent} target='#target' items={menuItems} created={created} beforeOpen={beforeOpen} />
        </div>
    );
    function created() {
        cMenu.enableItems(['Display Settings'], false);
    };
    function beforeOpen() {
        cMenu.enableItems(['Medium icons'], false);
    };
}
export default App;
ReactDom.render(<App />,document.getElementById('element'));

To disable sub menu items, use the beforeOpen event.
