18 Jan 20237 minutes to read

The context menu can be customized using the contextMenuSettings, menuOpen, and menuClick events.

The following example shows adding a custom item in the context menu.

The contextMenuSettings is used to add new menu item. The menuOpen event is used to add the icon to the new menu item. The menuClick event is used to add an event handler to the new menu item.

app.jsx

import { DetailsView, FileManagerComponent, NavigationPane, Toolbar, Inject } from '@syncfusion/ej2-react-filemanager';
import * as React from 'react';
function App() {
    let fileObj;
    let hostUrl = "https://ej2-aspcore-service.azurewebsites.net/";
    function menuClick(args) {
        if (args.item.text === 'Custom') {
            alert('You have clicked custom menu item');
        }
    }
    function menuOpen(args) {
        for (const i in args.items) {
            if (args.items[i].id === fileObj.element.id + '_cm_custom') {
                args.items[i].iconCss = 'e-icons e-fe-tick';
            }
        }
    }
    return (<div>
      <div className="control-section">
          <FileManagerComponent ref={s => (fileObj = s)} id="file" view="Details" ajaxSettings={{
