SP2013 How to do vertical flyout menu in top navigation

I have a problem to get the vertical flyouts to work in SP2013, I try to do it the SP2010 way to change the DynamicDisplayLevel but no luck.. Need help on this to achieve the same functionally as we had on SP2010.

I tried also to enable the publishing feature on all sites with no luck, or does it require a restart or so?

Menu item
       - Page 1
               - Page 2
       - Page 3
