title: Select Multiple Buttons using angular
body: <pre class="lang-html prettyprint-override"><code>&lt;div *ngFor=&quot;let value of values&quot;&gt;`
   &lt;button&gt;{{value}}&lt;/button&gt;`
  &lt;/div&gt;
  </code></pre>
  <p>On click I need to change the background color of the selected buttons.</p>
