Icons

The menu item contains an icon/image in it to provide a visual representation of an action.
To place the icon on a menu item, set the iconCss property with the required icon CSS. By default, the icon is positioned at the left of the menu item. In the following sample, the icons of File and Edit menu items and Open, Save, Cut, Copy,and Paste sub menu items are added using the iconCss property.

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

enableRipple(true);

@Component({
    selector: 'app-root',
    template: `<ejs-menu #menu [items]='menuItems'></ejs-menu>`
})

export class AppComponent {
    //Menu items definition
    private menuItems: MenuItemModel[] = [
        {
            text: 'File',
            iconCss: 'em-icons e-file',
            items: [
                { text: 'Open', iconCss: 'em-icons e-open' },
                { text: 'Save', iconCss: 'e-icons e-save' },
                { separator: true },
                { text: 'Exit' }
            ]
        },
        {
            text: 'Edit',
            iconCss: 'em-icons e-edit',
            items: [
                { text: 'Cut', iconCss: 'em-icons e-cut' },
                { text: 'Copy', iconCss: 'em-icons e-copy' },
                { text: 'Paste', iconCss: 'em-icons e-paste' }
            ]
        },
        {
            text: 'View',
            items: [
                { text: 'Toolbar' },
                { text: 'Sidebar' },
                { text: 'Full Screen' }
            ]
        },
        {
            text: 'Tools',
            items: [
                { text: 'Spelling & Grammar' },
                { text: 'Customize' },
                { text: 'Options' }
            ]
        },
        { text: 'Go' },
        { text: 'Help' }
    ];
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MenuModule } from '@syncfusion/ej2-angular-navigations';

import { AppComponent } from './app.component';

@NgModule({
    imports: [BrowserModule, MenuModule],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Navigation in Menu is used to navigate to the other web page when a menu item is clicked.
It can be achieved by providing a link to the menu item using the url property. In the following sample, the Navigation URL is added to sub menu items using the url property.

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

enableRipple(true);

@Component({
    selector: 'app-root',
    template: `<ejs-menu #menu [items]='menuItems' (beforeItemRender)='beforeItemRender($event)'></ejs-menu>`
})

export class AppComponent {
    //Menu items definition
    private menuItems: MenuItemModel[] = [
        {
            text: 'Appliances',
            items: [
                { text: 'Washing Machine', url: 'https://www.google.com/search?q=washing+machine' },
                { text: 'Air Conditioners', url: 'https://www.google.com/search?q=air+conditioners' }
            ]
        },
        {
            text: 'Mobile',
            items: [
                { text: 'Headphones', url: 'https://www.google.com/search?q=headphones' },
                { text: 'Memory Cards', url: 'https://www.google.com/search?q=memory+cards' },
                { text: 'Power Banks', url: 'https://www.google.com/search?q=power+banks' }
            ]
        },
        {
            text: 'Entertainment',
            items: [
                { text: 'Televisions', url: 'https://www.google.com/search?q=televisions' },
                { text: 'Home Theatres', url: 'https://www.google.com/search?q=home+theatres' },
                { text: 'Gaming Laptops', url: 'https://www.google.com/search?q=gaming+laptops' }
            ]
        },
        { text: 'Fashion', url: 'https://www.google.com/search?q=fashion' },
        { text: 'Offers', url: 'https://www.google.com/search?q=offers' }
    ];

    private beforeItemRender(args: MenuEventArgs): void {
        if (args.item.url) {
            // To open url in blank page.
            args.element.getElementsByTagName('a')[0].setAttribute('target', '_blank');
        }
    }
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MenuModule } from '@syncfusion/ej2-angular-navigations';

import { AppComponent } from './app.component';

@NgModule({
    imports: [BrowserModule, MenuModule],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Multilevel nesting

The Menu supports multiple level nesting, and it can be achieved by mapping the items property inside the parent menuItems.
In the following sample, three-level nesting of menu has been provided.

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

enableRipple(true);

@Component({
    selector: 'app-root',
    template: `<ejs-menu #menu [items]='menuItems'></ejs-menu>`
})

export class AppComponent {
    private menuItems: MenuItemModel[] = [
        {
            text: 'Fashion',
            items: [
                {
                    text: 'Men Fashion',
                    items: [
                        {
                            text: 'Personal Care',
                            items: [
                                { text: 'Trimmers' },
                                { text: 'Shavers' }
                            ]
                        },
                        {
                            text: 'Clothing',
                            items: [
                                { text: 'Shirts' },
                                { text: 'Jackets' },
                                { text: 'Track Suits' }
                            ]
                        },
                        { text: 'Footwear' }
                    ]
                },
                {
                    text: 'Women Fashion',
                    items: [
                        {
                            text: 'Clothing',
                            items: [
                                { text: 'Kurtas' },
                                { text: 'Salwars' },
                                { text: 'Sarees' }
                            ]
                        },
                        {
                            text: 'Jewellery',
                            items: [
                                { text: 'Nosepins' },
                                { text: 'Anklets' }
                            ]
                        }
                    ]
                }
            ]
        },
        {
            text: 'Home & Living',
            items: [
                {
                    text: 'Washing Machine',
                    items: [
                        { text: 'Fully Automatic' },
                        { text: 'Semi Automatic' }
                    ]
                },
                {
                    text: 'Air Conditioners',
                    items: [
                        { text: 'Inverter ACs' },
                        { text: 'Split ACs' }
                    ]
                }
            ]
        },
        { text: 'Accessories' },
        { text: 'Sports' },
        { text: 'Gaming' }
    ];
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MenuModule } from '@syncfusion/ej2-angular-navigations';

import { AppComponent } from './app.component';

@NgModule({
    imports: [BrowserModule, MenuModule],

    bootstrap: [AppComponent]
})
export class AppModule { }

You can achieve multi level nesting with data source by mapping name of the child items to the children sub-property of fields property. Also, we can specify id property for menu items. For more information, refer to the data source binding section.
The below table represents the MenuItem properties and it’s description.

Property Name Type Description  
  iconCss string Defines class/multiple classes separated by a space for the menu Item that is used to include an icon. Menu Item can include font icon and sprite image.
