Separate lists for displaying WooCommerce categories, subcategories, and products
Article Introduction:WooCommerce gives you a few options as to what you can display on the archive page: Product Categories (on the main store page) or Subcategories (on the category pages) Products and Categories When I build a store, I usually choose the third Options: Product and Category/Subcategory. This means visitors to my store can select products directly from the homepage or refine their searches by clicking on product category profiles. However, this approach has a drawback: it displays categories/subcategories together, with no separation between the two. This means that if your product image is a different size than the product image, the layout may look a little confusing. Even if your images are the same size, if a row in the archive page contains both a category and a product, the "Add" for the category is missing.
