Displaying All Products in All Subcategories of a Parent Category

[rge]

I am using the columanr layout and am trying to figure out how to display al products from a top level category instead of display the sub-categories. For example, if I have: top1 ->sub1(prod1, prod2) sub2(prod3, prod4). When I click on top1 (category_id 70), I would like to isplay all the products in the subcategories og top1.

This would require custom coding. You may be able to use a version of yellow1912's "all categories and products on one page" mod - see the thread all products in a category, show in one page,order by sub-categories.
