The Navbar isn't unfortunately able to accomodate a link as well as an anchor. The reason for this is due to the rise in mobile/repsonsive sites which use touch screen devices. Somone trying to access the nav using a touch screen device would also activate the link and then lose the drop down when the page redirected.
There's no official way to do this that I'm aware of, as it will probably be a js hack. There are some posts on google relating to fixing this inside bootstrap by changing the class, but they seem to disable the drop down menu and only activate the link.Go to the full post
