title: Angular isState - how to make comparision inside ng-if?
body: <p>THE SITUATION:</p>
  
  <p>Hello guys.
  I am using isState for my angular app.</p>
  
  <p>This is the documentation page:</p>
  
  <p><a href="http://angular-ui.github.io/ui-router/site/#/api/ui.router.state.filter:isState" rel="nofollow">http://angular-ui.github.io/ui-router/site/#/api/ui.router.state.filter:isState</a></p>
  
  <p>I have to make a simple check, inside ng-if, to see if the state is equal 'A' or 'B'.</p>
  
  <p>THE CODE:</p>
  
  <p>This is the list that contain the navigation:
  (i should make the check inside that ng-if)</p>
  
  <pre><code>&lt;ul class="menu-extra list-inline pull-right" ng-if="is_master' | isState "&gt;
  
  &lt;/ul&gt;
  </code></pre>
  
  <p>THE QUESTION:</p>
  
  <p>How can i make a comparision, inside the ng-if, to check if the state is equal a certain state OR a certain another state?</p>
  
  <p>Thank you!</p>
