What is the equivalent of <template *ngFor in Angular 2?
<p>I want to do something like this:</p>

<pre><code>&lt;div *ngFor="let parent of parents"&gt;
    &lt;div *ngFor="let child of parent.children"&gt;
    &lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>but I don't want that extra outer div. From what i've been able to find searching, in Angular 1 I could achieve this by doing this:</p>

<pre><code>&lt;template *ngFor="let parent of parents"&gt;
    &lt;div *ngFor="let child of parent.children"&gt;
    &lt;/div&gt;
&lt;/template&gt;
</code></pre>

<p>This doesn't seem to work in Angular 2 though. What's the correct way to do this?</p>
