title: Angular 2 material : sidenav toggle from component
body: <p>I'm using Angular 2 Material sidenav in my project this way:</p>
  
  <pre><code>&lt;md-sidenav-layout&gt;
    &lt;md-sidenav #start mode="side" [opened]="true"&gt;
        &lt;md-nav-list&gt;
        &lt;/md-nav-list&gt;
    &lt;/md-sidenav&gt;
  
    &lt;button md-button (click)="start.toggle()"&gt;Close&lt;/button&gt;
  
    &lt;router-outlet&gt;&lt;/router-outlet&gt;
  
  &lt;/md-sidenav-layout&gt;
  </code></pre>
  
  <p>How to call <code>start.toggle()</code> from my component instead of element with click event?</p>
  
  <p>Thank you for reading</p>
