MetisMenu Angular 2 - not working on first load

metisMenu not working on initial or first load. After refresh it works fine,

My app.component.ts looks like this,

/// <reference path="../typings/globals/jquery/index.d.ts" />;

import { Router } from '@angular/router';
import { Component, OnInit, AfterViewInit } from '@angular/core';

@Component({
    moduleId: module.id,
    selector: 'app-tag',
    templateUrl: 'app.component.html',
})
export class AppComponent implements OnInit, AfterViewInit {
    constructor(private _router: Router) {
    }

    ngOnInit(): void {
    }

    ngAfterViewInit() {
        (<any>$('#side-menu')).metisMenu();
    }
}

My menu items looks like this,

                    <li>
                        <a href="#"><i class="fa fa-volume-control-phone fa-fw"></i> Heading1<span class="fa arrow"></span></a>
                        <ul class="nav nav-second-level">
                            <li><a [routerLink]="['/h1c1']">H1-Child1</a></li>
                        </ul>
                    </li>
                    <li>
                        <a href="#"><i class="fa fa-users fa-fw"></i> Heading 2<span class="fa arrow"></span></a>
                        <ul class="nav nav-second-level">
                            <li><a [routerLink]="['/h2c1']">H2-Child1</a></li>
                        </ul>
                    </li>

I’m not getting any error. All the menu items are expanded by default on the first load. When I click on the head item, the page gets refreshed and all the menu items are collapsed and everything works fine from then on…

This worked for me

first declare jquery after your imports declare var jQuery:any;

replace this: (<any>$(‘#side-menu’)).metisMenu();

with this: jQuery(‘#side-menu’).metisMenu();

@BlankHrt - Me neither. In the end I built a vanilla Angular 4 component:

Dependencies:

"@angular/core": "4.1.2",
"@ng-bootstrap/ng-bootstrap": "^1.0.0-beta.4"

Component:

<div class="navbar-default sidebar" role="navigation">
	<div class="sidebar-nav navbar-collapse">
		<ul class="nav" id="side-menu">
			<li *ngFor="let menu of menuDefinition">
				<!-- Top level menu -->
				<a href="{{menu.href}}"
				   *ngIf="!menu.children || menu.children.length == 0">
					<i class="fa {{menu.icon}}"></i>{{menu.text}}
				</a>
				<!-- Top level menu with children -->
				<a href="{{menu.href}}"
				   *ngIf="menu.children && menu.children.length > 0"
				   (click)="menu.expanded=!menu.expanded;false;"
				   [attr.aria-expanded]="menu.expanded"
				   aria-controls="{{menu.childMenuId}}">
					<i class="fa {{menu.icon}}"></i>{{menu.text}}
					<span [ngClass]="{'fa-rotate-270': menu.expanded}" class="fa arrow fa-rotate-270"></span>
					<ul id="{{menu.childMenuId}}"
						[ngbCollapse]="!menu.expanded"
						class="nav nav-second-level">
						<li *ngFor="let childMenu of menu.children">
							<a href="{{childMenu.href}}">{{childMenu.text}}</a>
						</li>
					</ul>
				</a>
			</li>
		</ul>
	</div>
</div>

import {
	Component,
	AfterViewInit
} from '@angular/core';

@Component({
	selector: 'navigation',
	templateUrl: './navigation.component.html',
	styleUrls: ['./navigation.component.css']
})
export class NavigationComponent implements AfterViewInit {

	menuDefinition: Array<any> = [{
		text: 'Dashboard',
		icon: 'fa-dashboard fa-fw',
		href: '#'
	}, {
		text: 'Charts',
		icon: 'fa-bar-chart-o fa-fw',
		href: '#',
		expanded: true,
		childMenuId: 'chartsLinks',
		children: [{
			text: 'Flot Charts',
			href: '#'
		}, {
			text: 'Morris.js Charts',
			href: '#'
		}]
	}, {
		text: 'Tables',
		icon: 'fa-table fa-fw',
		href: '#'
	}, {
		text: 'Forms',
		icon: 'fa-edit fa-fw',
		href: '#'
	}, {
		text: 'UI Elements',
		icon: 'fa-wrench fa-fw',
		href: '#',
		expanded: true,
		childMenuId: 'uiLinks',
		children: [{
			text: 'Panels and Wells',
			href: '#'

			href: '#'
		}, {
			text: 'Typography',
			href: '#'
		}, {
			text: 'Icons',
			href: '#'
		}, {
			text: 'Grid',
			href: '#'
		}]
	}];

	ngAfterViewInit(): void {
	}
}
