title: PrimeNG <p-menu> how to keep click menu item selected (Angular 7)
body: <p>I am using primeNg  component in angular 7 project.</p>
  
  <pre><code>&lt;p-menu [model]="items" &gt;&lt;/p-menu&gt;
  </code></pre>
  
  <p>while dealing with this component we don't have access to its internal structure to show click menu item as selected. to push active class when a certain menu will be selected and change its color.</p>
  
  <p>Does anybody have any idea about this?</p>
