To reduce confusion around what this widget actually does, the old "Show Products" and "Show SubCategories" options in the Product List Grid widget have been merged into a new setting called "Product Display Option". Select from

  • Products OR Subcategories
  • Subcategories Only
  • Products Only

The default value for this setting is 'Products OR Subcategories', meaning the widget will display products first, or subcategories if no products are found.  

If your website structure has both products and categories sitting at the same level, add 2 of these widgets to the page template. Use one to display Subcategories, and the other to display Products.
