I've My categories Structure like this :
Music
-Genre
-Pop
-Rock
-Role
-Vocalist
-Guitarist
So Now I want to filter posts in such a way that a post should belong to ( either Pop or Rock) and (Vocalist)
So an or between genres and an and with the role
So speaking in wordpress terms in need multiple category_in or category_and which has category_in
Tricky right?
Any solution?
