    <h1>Moving Angular component from one parent component to another</h1>
    <p>
      This plunk demonstrates how to detach an Angular component from one parent component
      and attach it to another. With this approach, the 
      <a href="https://angular.io/api/core/OnDestroy">ngOnDestroy</a> method of the
      child component is only called by Angular when the parent that the child is currently 
      attached to is destroyed.
    </p>
    <div class="demo">
      <div class="col">
        <my-container name="Container 1" *ngIf="containerOneEnabled"></my-container>
      </div>
      <div class="col">
        <my-container name="Container 2" *ngIf="containerTwoEnabled"></my-container>
      </div>
    </div>
    <ol>
      <li>Open browser console to monitor log statements.</li>
      <li><button (click)="moveChild()">Move Child</button></li>
      <li>
        <button (click)="destroyContainerOne()">Destroy Container 1</button>
        Note in console that only container 1 was destroyed, there is no log 
        statement from the child component that it was destroyed.
      </li>
      <li>
        <button (click)="destroyContainerTwo()">Destroy Container 2</button>
        Now we get a log statement in the console from both container 2 
        <b> and from the child component</b>.
      </li>
      <li>Refresh Plunker to do it again :)</li>
    </ol>
