Add or remove context menu items in React Context menu component

29 Aug 20237 minutes to read

ContextMenu items can be added or removed using the insertAfter, insertBefore and removeItems methods.

In the following example, the Display Settings menu items are added before the Personalize item, the Sort By menu items are added after the Refresh, and the Paste item is removed from context menu.

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'
                }
