Quick Start Example

import { Component } from '@angular/core';
import { MenuModule } from '@syncfusion/ej2-angular-navigations';
import { MenuItemModel } from '@syncfusion/ej2-angular-navigations';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

@Component({
  imports: [MenuModule],
  standalone: true,
  selector: 'app-root',
  template: `<ejs-menu [items]="menuItems"></ejs-menu>`
})
export class AppComponent {
  public menuItems: MenuItemModel[] = [
    {
      text: 'File',
      items: [
        { text: 'Open' },
        { text: 'Save' },
        { separator: true },
        { text: 'Exit' }
      ]
    },
    {
      text: 'Edit',
      items: [
        { text: 'Cut' },
        { text: 'Copy' },
        { text: 'Paste' }
      ]
    },
    { text: 'Help' }
  ];
}

CSS Setup:

@import '../node_modules/@syncfusion/ej2-base/styles/material3.css';
@import '../node_modules/@syncfusion/ej2-navigations/styles/material3.css';

Common Patterns

1. Menu with Icons

public menuItems: MenuItemModel[] = [
  {
    text: 'File',
    iconCss: 'e-icons e-file',
    items: [
      { text: 'Open', iconCss: 'e-icons e-open' },
      { text: 'Save', iconCss: 'e-icons e-save' }
    ]
  }
];

2. Menu with Animation

public animationSettings: MenuAnimationSettingsModel = {
  effect: 'FadeIn',
  duration: 800
};

Use in template: <ejs-menu [animationSettings]="animationSettings"></ejs-menu>

3. Menu with Events

public onItemSelect(args: MenuEventArgs): void {
  console.log('Selected item:', args.item.text);
}

Use in template: <ejs-menu (select)="onItemSelect($event)"></ejs-menu>

4. Dynamic Menu Modification

@ViewChild('menu')
public menuObj?: MenuComponent;

public addItem(): void {
  const newItem: MenuItemModel[] = [
    { text: 'New Menu Item' }
  ];
  this.menuObj?.insertAfter(newItem, 'File', false);
}
