I need to create a megamenu for a site which links to a bunch of category pages.
So I have megamenus for Product Type A & B which are also categories.
Under Product Type A there are headings for Materials, Brand & Usage.
Product Type B will also have a megamenu with a Brand subheading.
At the moment I have a category group for Brands and I'm just listing out all the categories in that group under the respective headings.
So what I need to do is make sure that under the Brand heading for Product Type A that only Brands that have entries that are also assigned to the Product Type A category show, and so on for Type B etc.
For most of the options in these menus I'm just dealing with categories because there won't be any overlap.
But there will for Brands and so I need to look at the entries and then build the list of category options from there.
Any idea how I go about that?
