Filtering results, twice

[gardenlevel]

I have about 4000 items in my database, what I want to do is filter a portal down to just the Items I want. So first I want a button that that filters the category list, then choosing a category filters the portal. I will be sorting first by a field named type, then by a field named category.

In other words, you choose between Fruits, Breads or Drinks. When you choose fruits a second list displays Apples, Bananas, pears. Choosing Apples shows a list of apples. On catch is that the category for some of the breads MIGHT be Apple, and they shouldn't show up under Fruits -> Apple.

Do I do this with relationship filtering, or scripts?

Never Mind, I fixed it, I was just adding one too many steps.
