    <md-sidenav #sidenav mode="side" color="primary">
     <md-toolbar color="primary"><span>Sidenav</span></md-toolbar>

          <button md-button class="sidenav-link" (click)="sidenav.close()">
            <md-icon>home</md-icon><span class="title"> HOME</span>
          </button>
      </md-sidenav>
      <app-toolbar [sidenav]="sidenav"></app-toolbar>
