Multiple categories or cutom taxonomy
I am looking to create different categories type for a specific project. Example will be : Books, Movies, Music and then each of those will have categories within. So they should be different taxonomies than the default Vanilla Category type. Basically I am looking at the same structure as Wordpress custom taxonomy since version 3.0. Or the solution to my problem could be also be to allow multiple categories for each discussion.
I know this is not how Vanilla has been built but i wondering if someone ever accomplished this. Right now the DB only allow 1 category per discussion. There should be a new table with discussions ID linked to category and maybe custom taxonomy IDs. The Wordpress structure is a good example of what I am looking for.
Sorry for my English, this is not my first language.
I would appreciate feedback on this if anyone ever attempted this.
