How to open a submenu of the navbar automatically?

Hi

How can I in code open a submenu of the bootstrap navbar and select on of the menu items, without processing the function behind this menu item.

In other words: after I login and it shows the main page with navbar menu, it should open a submenu and highlight a specific option. And nothing more.
I have tried setMenuSelected, but that does not work.
