title: Maintain Multi-Level Menu Selection
body: <p>Using one of the ASP.Net MVC5 templates, how can I maintain menu selection when selecting an item from a multi-level menu? </p>
  
  <p>When a sub-menu is clicked, the page loads but there is no indication which menu item has been clicked. It is possible to expand the menu and eventually it will show the indicator but how can this be set as default behaviour?</p>
  
  <p>If the user clicks on a root-level menu item, after the page loads, there is clear indication which menu item has been clicked.</p>
