hi, in the form I used the dynaic field in query free, and aded this code SELECT title as text, id as value FROM #__categories WHERE created_user_id = $user->id AND parent_id=8
the final part you just change the number for the nomber of the principal category that contains those subcategories, the result for me it shows me only the subcategories created by the current logged in user, that belong to that parent category
