Hover Menu Dropdown

I’m trying to get my submenu (the one under the picture) to perform like the one on the upper right corner (above the picture).

Basically, if you hover on the About, you see search below it.

I’d like to have the submenu perform the same – I’d like to see the 7 “Categories” and nothing under them until you hover over it. I can’t seem to figure out how to get that done.

Here is my site:
