As many of you know, sub pages in the blix theme are added directly to the main navigation. I have been able to fix that by modifying the CSS.
You can see at http://www.jacobjmorris.com. (notice how Portfolio and Resume are subpages of About).
However, I will have subpages to Portfolio, but when I create them, WordPress messes up my drop down menu. Is there some PHP code somewhere I can add, so that tier 3 pages don't show in the navigation at all?
