Users finding products that exist in multiple categories

I'm trying to find a way for users to find products that exist in two categories.

I have the 'Products Filter for eShop' module published, but it's not doing quite what I want.

The use case is as follows:

The site lists schoolbooks. Books are assigned to two categories: Subject (Maths, Geography, History etc.) and Grade (1,2,3,4 etc)

Users would like to find, say, Geography books for 2nd Grade.

Right now, they can drill down to the Geography category, but will see books for all grades there. OR then can access the 2nd Grade category, but will see books for all subjects there.

I'm trying to find the way for users to drill into Geography, then filter by grade.

Any hints?

Hello Peter Mee,

There is no way to implement the feature that you want now. At each time, you can view all of products from a specific category.

Sincerely, Giang

I will think more about this. If I find a possible solution, I will let you know!
