Expected behavior As this: https://mdbootstrap.com/previews/mdb-ui-kit/sidenav/4.html

Actual behavior it does not work

dynamic menu behavior video https://streamable.com/rgztbk

Is it possible that because our menu is dynamic it doesn't work the same as the demo?

we use this for iterate:

<ng-container *ngFor="let subMenu of category.Menu.submenu>"

but also we try over

<mdb-sidenav-item>

and it doesn't work either

our Code:

  <ul class="sidenav-menu">
    <ng-container *ngFor="let category of menuData.detail">
      <mdb-sidenav-item>

        <a class="sidenav-link" tabindex="0" mdbRipple mdbRipple [href]="category.Menu.link ? category.Menu.link : '#'">
          <i [class]="category.Menu.icon"></i>
          <span>{{ category.Menu.label }}</span>
        </a>

        <ul class="sidenav-collapse" mdbCollapse>
          **<ng-container *ngFor="let subMenu of category.Menu.submenu">**
            <li class="sidenav-item">
              <a class="sidenav-link" tabindex="0" mdbRipple [href]="subMenu.link">
                {{ subMenu.label }}
              </a>
            </li>
          </ng-container>
        </ul>
      </mdb-sidenav-item>
    </ng-container>
  </ul>

</mdb-sidenav>
<mdb-sidenav-content #sidenavContent>

  <main style="margin-top: 58px" class="pb-5">
    <router-outlet></router-outlet>
  </main>
</mdb-sidenav-content>   </mdb-sidenav-layout>

Resources (screenshots, code snippets etc.)

We can see that the HTML structures change with our dynamic way of building the menu, do you recommend something for this?
