title: Angular2 ngFor - skip if no value
body: <p>I have this json object:</p>
  
  <pre class="lang-js prettyprint-override"><code>data = {
  
    "name": "somename",
    "items": [
      {
        "title": "Item 1",
        "description": "Some description for item1"
      },
      {
        "title": "Item 2",
        ""
      },
      {
        "title": "Item 3",
        "description": "Some description for item3"
      }
    ]
  }
  </code></pre>
  
  <p>What would be the recommended way, with rc2, to *ngFor and display only items that have a description?</p>
  
  <p>Html Template: </p>
  
  <pre><code>&lt;li *ngFor="let item of data.items" class="item"&gt;
          &lt;div&gt;{{item.title}}&lt;/div&gt;
          &lt;div&gt;{{item.description}}&lt;/div&gt;
  &lt;/li&gt;
  </code></pre>
