I have defined taxonomy terms to classify products:
--Catechetics-Reasons for Believing Pamphlets
--Moral and Social
I can display any of these sets of products by going to (for example):
How can I display more than one category on the same page? Is it better to use views? If so, how can I filter by one term OR another? Can I group them with a heading above each group showing the term and, if I do it this way how do I filter with an argument in the URL?
