I want to feature some items from a collection on a page but filtered by that specific page.
So i can have a dynamic list bound to that collection and i can filter by a term that i type into the page. But i want that term to be from a field on the pages collection.
So say a collection of articles. And another collection of images. In the images collection there is a category and on the main article page i can filter the images by the category - but i want, instead of typing in a fixed name, to take the category from the article collection.
Does that make sense? It seems like such a common task?
