select which category show on a menu over slider

is any way to select which category show on the menu over the slider???

What happened if you got 20 categories but you only want to show only a few ones???

I think it could be a good functionality to add.

Hey!
Of cause there is such feature. You need to adjust your menu on page Appearance --> Menus in your dashboard. Here is the tutorial http://codex.wordpress.org/WordPress_Menu_User_Guide.
