I have a small problem with dynamic lists. I have two lists, each fetching data from 2 collections (products & related products). For me, that is the only difference between to two dynamic lists. However, I want to add a filter to the related product dynamic list and it seems like I cant. The option to add a filter isn't on the menu.
Any ideas why it isn't on the related product dynamic list & not on the product list?
