   I'm not entirely sure I understand what you're asking. Are you saying you want an array with just the top categories? And are you asking for the MySQL query to obtain that?

   Yes I want an array with just the top categories! Either mysql query or WP templates tag is OK!templates tag is preferred

   I don't think it's possible with template tags (although I don't understand why not). I see no parameters that allow you to just pull top-level categories.

   But the MySQL query would look something like:

   SELECT cat_ID FROM wp_categories WHERE category_parent = 0

   Note that in WP2.1 or greater, this will also retrieve categories for your blogrolls since they rolled that into the wp_categories table in Ella.

   If you want to eliminate those, you would have to a bit more complicated query with joins to another table or two. Do you need that, too?
