title: How to add multiple conditions in ng-class using Angular.js
body: <p>I need to add multiple conditions <code>ng-class</code> using Angular.js. I am explaining my code below.</p>
  
  <pre><code>&lt;li ng-class="{'active':($root.stateName==='app.settings')}"&gt;&lt;a ui-sref="app.settings"&gt;Settings&lt;/a&gt;&lt;/li&gt;
  </code></pre>
  
  <p>Here I need to add another two conditions <code>i.e-$root.stateName==='app.settings.area' and $root.stateName==='app.settings.area.manageState'</code> with that existing conditions with <code>OR</code> condition.</p>
