Usage

Follow below steps to add multi level list in your project

1. Import NgMaterialMultilevelMenuModule

You need to import the NgMaterialMultilevelMenuModule in the module of your app where you want to use it.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

/* Import the module*/
import { NgMaterialMultilevelMenuModule } from 'ng-material-multilevel-menu';

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

@NgModule({
    declarations: [
    AppComponent
    ],
    imports: [
    BrowserModule,
    NgMaterialMultilevelMenuModule // Import here
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule { }

2. Use in your HTML

In your HTML: Use the <ng-material-multilevel-menu> wherever you like in your project.

<ng-material-multilevel-menu  
    [configuration]='config' 
    [items]='appitems'
    (selectedItem)="selectedItem($event)" 
    (menuIsReady)="menuIsReady($event)" 
    (selectedLabel)="selectedLabel($event)">
</ng-material-multilevel-menu>

3. Structure of array to display the list

Make sure you structure of array should look like array shown below,

appitems = [

        externalRedirect: true,
        hrefTargetType: '_blank' // _blank|_self|_parent|_top|framename
    },

                        faIcon: 'fa-allergies' // Font awesome default prefix is fas
                    },
                    {
                        label: 'Item 1.2.2',
                        faIcon: 'fas fa-ambulance',
                        items: [
                            {
                                label: 'Item 1.2.2.1',
                                faIcon: 'fas fa-anchor',  // Still you can specify if you want to
                                onSelected: function() {
                                    console.log('Item 1.2.2.1');
                                }
                            }
                        ]
                    }
                ]
            }
        ]
    },

        icon: 'alarm',
        items: [

- interfaceWithRoute: boolean => [required] only if you want to use Angular Routing with this menu.
- highlightOnSelect: boolean => [optional] If you want to highlight the clicked item in the list, then you can do that by making it true. The default value will be false.

Misc

1. Exapand/ Collapse all Menu

You can expand all the menu and Collapse all the menus. Below is example how you can do that,

import { MultilevelMenuService, ExpandCollapseStatusEnum } from 'ng-material-multilevel-menu';

export class AppComponent {
    constructor(
        private multilevelMenuService: MultilevelMenuService
    ) {}

    setExpandCollapseStatus(type: ExpandCollapseStatusEnum) {
        this.multilevelMenuService.setMenuExapandCollpaseStatus(type);
    }
}

2. Select Menu By ID

You can expand all the menu and Collapse all the menus. Below is example how you can do that,

import { MultilevelMenuService, MultilevelNodes } from 'ng-material-multilevel-menu';

export class AppComponent {
    menuWithID: MultilevelNodes[] = null

    constructor(
        private multilevelMenuService: MultilevelMenuService
    ) {}

    menuIsReady(menus: MultilevelNodes[]) {
        this.menuWithID = menus;
    }

    selectMenuID(MenuID){
        this.multilevelMenuService.selectMenuByID(MenuID);
    }

}

3. Building Custom Templates

In this section, you will find useful information if you are planning to write your own templates.

First and very important is MultilevelNodes interface, every menu item implements this interface. Make sure you look into each property of this interface when building custom menu templates. For example properties like isSelected, hasChilden, expanded, disabled, items, label, and so on are extremely helpful, have look into some demos here.
You actually don't have to write Slide-In/ Slide-Out, Arrow Rotation animation. The module exports these animations out of the box, so you can import them and use it as shown below.

demo.component.ts:

import {SlideInOut, ExpandedRTL, ExpandedLTR } from 'ng-material-multilevel-menu';

@Component({
    selector: 'app-demo',
    templateUrl: './demo.component.html',
    styleUrls: ['./demo.component.css'],
    animations: [
      SlideInOut,
      ExpandedLTR,
      ExpandedRTL,
    ]
})

You have decided to write a custom template, then you have to write the corresponding CSS for the same.
Below is a very simple example of the custom menu templates,

demo.component.html:

 <ng-material-multilevel-menu [items]='appitems' [configuration]='config' (selectedItem)="selectedItem($event)">
    <ng-template #listTemplate let-item="item" let-configuration="configuration">
        <div class="my-cool-menu-item" [dir]="configuration.rtlLayout  ? 'rtl' : 'ltr'">
            <div class="title-and-image">
                <div class="icon-container">
                    <span [ngClass]="getClass(item)"></span>
                </div>
                <div class="label-container">
                    <span>{{item.label}}</span>
                </div>
            </div>
            <div class="icon-arrow-container" *ngIf='item.hasChilden'>
                <mat-icon *ngIf="!configuration.rtlLayout" [@ExpandedLTR]="item.expanded ? 'yes' : 'no'">
                    keyboard_arrow_down
                </mat-icon>
                <mat-icon *ngIf="configuration.rtlLayout" [@ExpandedRTL]="item.expanded ? 'yes' : 'no'">
                    keyboard_arrow_down
                </mat-icon>
            </div>
        </div>
    </ng-template>
</ng-material-multilevel-menu>
