title: Highlight current item with all previous item in a menu
body: <p><img src="https://i.stack.imgur.com/5LAEe.jpg" alt="menubar navigation"></p>
  
  <p>Here i attached my menubar.My web page is fully scrollbar page shift type(i.e,a single page containing six pages that would be scrollable on clicking menu items). While i click my menu item the highlight of my menu item could be like as in the attached image.Still now i work with a single menu item highlight as for current page,but here my need is while i click my fourth menu then the current menu item with all previous menu items also need to be highlighted.How can i proceed this?</p>
