Only display tag options for specific category in module?

category_id: The FUEL category it belongs to. This can come in handy when you want to group tags together. For example, you could create an "articles" category to group the tags together.
How do I apply this to a module? For example, I have an Articles and Classifieds module and category, and I only want the tag options to appear to the corresponding modules.

In your "has_many" relationships in your model, you can use the "where" parameter to only select tags that maybe have a specific category ID:
