Dear sameretto,

The navbar on mobile devices will hide automatically after the click if the link which has been clicked contains a routerLink directive.

If you don't want this behavior - to navbar not hide after clicking on a link, please use the Router's navigate() method.

Here's the sample code which works fine for me:

.html:

<li class="nav-item active">
 <a class="nav-link waves-light" mdbWavesEffect (click)="navigateTo('home')">Home<span class="sr-only">(current)</span></a>
</li>

.ts:

constructor(private router: Router) {

  }

  navigateTo(path: string){
    this.router.navigate([path]);
  }

Best Regards,

Damian
