The selectedIndex attribute is failing to function properly for the mat-tab-nav-bar tabs in Angular Material

I've implemented the tab navigation code as shown below:

<nav mat-tab-nav-bar [selectedIndex]="0">
    <a mat-tab-link 
        *ngFor="let link of navLinks; let i = index;"
        [routerLink]="link.path"
        routerLinkActive #rla="routerLinkActive"
        [active]="rla.isActive">
        <div class="link-tab-label">{{link.label}}</div>
        <mat-icon class="link-tab-close" (click)="closeTab(i)">close</mat-icon>
    </a>
</nav>

However, upon running the project, I encounter the following error message:

compiler.js:485 Uncaught Error: Template parse errors:
Can't bind to 'selectedIndex' since it isn't a known property of 'nav'. ("
        <mat-card>
          <mat-card-content>
              <nav mat-tab-nav-bar [ERROR ->][selectedIndex]="0">

Is there a proper way to use selectedIndex with mat-tab-nav-bar?

Answer №1

mat-tab-nav-bar does not come equipped with a selectedIndex property, and the items within it labeled as mat-tab-link are not typical tabs. Instead, mat-tab-nav-bar offers a tab-like user interface for navigating between routes. To designate which link is active, you need to set the active route using your application's router. The active "tab" appears highlighted thanks to the use of the routerLinkActive directive in conjunction with the active property.
