  </ul>
  
  <p>I am new on Angular2. I have use "ngFor" to iterate over array of objects and show them as matrix having 3 columns for each row. For example;</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="row"&gt;
    &lt;div class="col"&gt;
      &lt;div class="card"&gt;&lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="col"&gt;
      &lt;div class="card"&gt;&lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="col"&gt;
      &lt;div class="card"&gt;&lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  &lt;div class="row"&gt;
  ...
  &lt;/div&gt;
  &lt;div class="row"&gt;
  ...
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Could anyone help me on this?
  Thanks,</p>
