Could you provide more information on the solution you would like to get? The scroll spy component only have an activeLinkChange output.

You can find information about the Smooth Scroll usage in our documentation: https://mdbootstrap.com/docs/angular/advanced/scroll/

Sorry, my full code is here: (nav.html)

<ul mdbScrollSpy="navScroll" (activeLinkChange)="getActiveLink($event)" class="navbar-nav ml-auto text-uppercase font-weight-bold font-small">

  <li class="nav-item" (click)="nav.toggle()">
    <a class="nav-link waves-light" mdbScrollSpyLink="profile" mdbWavesEffect>Szolgáltatások</a>
  </li>
  <li class="nav-item" (click)="nav.toggle()">
    <a class="nav-link waves-light" mdbScrollSpyLink="benefit" mdbWavesEffect>Előnyök</a>
  </li>
  <li class="nav-item" (click)="nav.toggle()">
    <a class="nav-link waves-light" mdbScrollSpyLink="reference" mdbWavesEffect>Referenciák</a>
  </li>
  <li class="nav-item" (click)="nav.toggle()">
    <a class="nav-link waves-light" mdbScrollSpyLink="about" mdbWavesEffect>Cégünkről</a>
  </li>
  <li class="nav-item" (click)="nav.toggle()">
    <a class="nav-link waves-light" mdbScrollSpyLink="contact" mdbWavesEffect>Elérhetőségek</a>
  </li>

</ul>

nav.ts:

getActiveLink(event: any): void { console.log('event', event); }

guio

Is there a problem only with the activeLinkChange event or the scrollspy doesn't work at all? Please note that the mdbScrollSpyElement directive should be used to spy on the internal scroll of the specific element. If you want to spy on the main page scroll, you should use mdbScrollSpyWindow like in this example:
