WooCommerce - Nested Category/Subcategory Layout, FIXED: show subcategory content

/**
 * The Template for displaying product archives, including the main shop page which is a post type archive

 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you

 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.

how to limit no. of products to be shown in each category?

Hi! Thanks for your code! I have same problem as Sascha, any recommendation to solve it?

Hi. Superior script. Its that was I'm looking for. But I've one problem. I've a few categories and one category has subcategories. On the shop page it will show products from the subcategories on the parent category and than twice in the subcategories.

It should be

Cat1

• SubCat1
  -- Prod 1
  -- Prod 2
  -- Prod 3
• SubCat1
  -- Prod 4
  -- Prod 5
• SubCat1
  -- Prod 6
  -- Prod 7
  -- Prod 8
  Cat2
  -- Prod 9
  -- Prod 10
  Cat3
  -- Prod 11
  -- Prod 12
  Cat4
  -- Prod 13
  -- Prod 14

But it looks like this ;-(

Cat1 -- Prod 1 -- Prod 2 -- Prod 3 -- Prod 4 -- Prod 5 -- Prod 6 -- Prod 7 -- Prod 8

• SubCat1
  -- Prod 1
  -- Prod 2
  -- Prod 3
• SubCat1
  -- Prod 4
  -- Prod 5
• SubCat1
  -- Prod 6
  -- Prod 7
  -- Prod 8
  Cat2
  -- Prod 9
  -- Prod 10
  Cat3
  -- Prod 11
  -- Prod 12
  Cat4
  -- Prod 13
  -- Prod 14

Has anyone a tip for me? How can I fix?

Thanks Sascha

Anyone get a solution for that ?
