Implementing the Syncfusion React Menu Component

When to Use This Skill

• Building navigation menus: File menus, application menus, main navigation bars
• Dropdown menus: User action menus, context-sensitive options
• Sub-menu systems: Multi-level hierarchical navigation
• Hamburger/mobile menus: Responsive menu for mobile devices
• Menu customization: Adding/removing items, icons, separators, custom styling
• Event handling: Detecting menu item clicks, open/close events, item state changes
• Data-driven menus: Binding menus to JSON data structures (hierarchical or self-referential)
• Item state management: Enabling/disabling, showing/hiding, updating menu items
• Accessibility: Creating keyboard-navigable, screen reader-friendly menus
• RTL support: Right-to-left language menus
• Scrollable menus: Large menus with horizontal/vertical scrolling
• Persistence: Saving menu state across page reloads

    {
      text: 'File',
      items: [
        { text: 'New' },
        { text: 'Open' },
        { text: 'Save' }
      ]
    },
    {
      text: 'Edit',
      items: [
        { text: 'Cut' },
        { text: 'Copy' },
        { text: 'Paste' }
      ]
    }
  ];

  return (
    <MenuComponent items={menuItems}></MenuComponent>
  );
}

export default App;

Quick Start Example

import { MenuComponent, MenuItemModel } from '@syncfusion/ej2-react-navigations';
import * as React from 'react';

function App() {
  // Define menu structure
  const menuItems: MenuItemModel[] = [
    {
      text: 'File',
      items: [
        { text: 'New' },
        { text: 'Open' },
        { text: 'Save' },
        { separator: true },
        { text: 'Exit' }
      ]
    },
    {
      text: 'Edit',
      items: [
        { text: 'Cut' },
        { text: 'Copy' },
        { text: 'Paste' }
      ]
    },
    {
      text: 'Help'
    }
  ];

  return (

Common Patterns

Pattern 1: Responding to Menu Item Selection

const handleMenuSelect = (args) => {
  console.log(`Selected: ${args.item.text}`);
  // Handle the selected menu item
};

<MenuComponent 
  items={menuItems} 
  select={handleMenuSelect}
></MenuComponent>

Pattern 2: Dynamically Adding Menu Items

let menuObj: MenuComponent;

const addMenuItem = () => {
  menuObj.insertAfter([{ text: 'New Item' }], 'File');
};

<MenuComponent 
  ref={(menu) => (menuObj = menu)} 
  items={menuItems}
></MenuComponent>

Pattern 3: Disabling Menu Items

const handleBeforeOpen = (args) => {
  if (args.item.text === 'Save') {
    args.item.disabled = true; // Disable based on condition
  }
};

<MenuComponent 
  items={menuItems} 
  beforeOpen={handleBeforeOpen}
></MenuComponent>
