Dear @Frederic

Let me answer your questions in the order in which you have asked them:

1) You have to change this space manually with css, 2) There's no possibility. Those links are marked as active with class .active, so you have to remove the .active class from every link after switching to the slim version.

Best Regards,

Damian

Here is also the code of Slim Sidenav :

<mdb-navbar-brand>
  <!-- Logo -->
  <li>
    <div class="logo-wrapper sn-ad-avatar-wrapper">
      <a href="#">
        <img src="https://mdbootstrap.com/img/Photos/Avatars/img%20(10).jpg"
             class="rounded-circle"><span>Anna Deynah</span>
      </a>
    </div>
  </li>
  <!--/. Logo -->
</mdb-navbar-brand>

<links>
  <!-- Side navigation links -->
  <li>
    <ul class="collapsible collapsible-accordion">
      <mdb-accordion [multiple]="false" aria-multiselectable="false">

        <!-- Simple link -->
        <mdb-accordion-item *ngFor="let option of menu" class="no-collase">
          <mdb-accordion-item-head routerLink="{{ option.routerLink }}" routerLinkActive='active' mdbWavesEffect>
            <i class="{{ option.icon }}"></i><span class="ml-1">{{ option.text}}</span>
          </mdb-accordion-item-head>
          <mdb-accordion-item-body></mdb-accordion-item-body>
        </mdb-accordion-item>

        <mdb-accordion-item class="no-collase">
          <mdb-accordion-item-head mdbWavesEffect (click)="sidenav.toggleSlim()">
            <i class="fas fa-angle-double-left"></i> Minimize
          </mdb-accordion-item-head>
          <mdb-accordion-item-body></mdb-accordion-item-body>
        </mdb-accordion-item>

      </mdb-accordion>
    </ul>
  </li>
  <!--/. Side navigation links -->
</links>
<div class="sidenav-bg mask-strong"></div>

Thank you.

Dear @Damian,

Thank you very much, Slim Sidenav works well !!!

I still have two questions:

1. when the Sidenav is Slim, the distance between the Slim Sidenav and the "content of the main" remains 15rem. Is it possible to reduce it (to 4rem for example) ?

2. When the "minimize" option is cliched, the option remains active. Is it possible that the option does not stay active?

Thank you
