Woo Categories Page

I want to create a simple shop where only the categories are listed and when you reach the bottom category, the products are shown.

Example:
Shop page:
Category 1 | Category 2 | Category 3
You click on Category 2:
Subcategory 1 | Subcategory 2
You click on Subcategory 1:
Product 1 | Product 2 | Product 3

How can I achieve something like this with Divi and why is it so darn complicated?

What I need to create is a custom All Product Categories template but what do I put in there? If I put a shop module, it shows the products directly, with no categories first.

 

I did that, however, I am now unable to create custom templates for All Product Categories. If I add a shop module there, it shows all of the products directly (from all subcategories) while I want to show subcategories until you've opened the bottom level subcategory where you will get to see the products in it.
