title: Ng-repeat-start in angular2 - aka repeat multiple elements using NgFor
body: <p>I need to repeat several <code>li</code>-elements in a list in Angular2 for each item. In angular 1.x I used <code>ng-repeat-start</code> and <code>ng-repeat-end</code> for this. I can't find the right way to do it in Angular 2. There are <a href="http://jilles.me/ng-repeat-in-angular2-ng-for/">some older blog posts</a> about this, but their suggestions don't work in the newest beta of Angular2.</p>
  
  <p>All <code>&lt;li&gt;</code>-elements should be repeated for each category:
  (which I would normally do with the attribute <code>*ngFor="#category of categories"</code> - but I can't find where to put it...</p>
  
  <p>Help?</p>
  
  <pre><code>&lt;ul class="dropdown-menu" role="menu"&gt;
      &lt;li class="dropdown-header"&gt;
          {{ category.title }}
      &lt;/li&gt;
      &lt;li&gt;
          &lt;a href="{{ '/music/' + tag.keyword }}" *ngFor="#tag of category.tags" [hidden]="tag.deleted === 1"&gt;{{ tag.tag_title_da }}&lt;/a&gt;
      &lt;/li&gt;
      &lt;li class="divider"&gt;&lt;/li&gt;
  
      &lt;li class="dropdown-header"&gt;Alle musikstykker&lt;/li&gt;
      &lt;li&gt;&lt;a href="/music/all"&gt;Alle musikstykker&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
