title: Angular 2 NgIf, dont render container element on condition but show its child elements
body: <p>How do you do something like the following in <strong>angular 2</strong>? I've written it in pseudo code to help explain better. </p>
  
  <p>I have tried <strong>applying classes</strong> but I <strong>don't want it to render the container div</strong> if possible. </p>
  
  <p>I have also tried the <strong>&lt; template ></strong> tag but I may be missing something. Thanks</p>
  
  <pre><code>&lt;!-- ngIf: isPromo --&gt;
  &lt;div class="promoContainer"&gt;
  &lt;!-- ngIf end --&gt;
  
  &lt;div class="item"&gt;...&lt;/item&gt;
  
  &lt;!-- ngIf: isPromo --&gt;
  &lt;/div&gt;
  &lt;!-- ngIf end --&gt;
  </code></pre>
