Virtuemart 2 displays products only in the exact categories they are assigned to. In many cases, however, you want your customers to see also all products in the child categories of the current category. This plugin, which can be configured to run automatically in the Backend, can be configured to add each product also to all parent categories, so it will appear also in the parent category listing. The reverse is also possible: Automatically remove each product from all parent categories and display it only in the very last category (leaf category). For child products, the plugin additionally allows the shop owner to automatically remove all categories or explicitly copy all categories from the parent product. This allows you to globally modify all child products to either not appear at all in the VirtueMart categories view in the frontend (because e.g. you display the child products on the parent product's page) or to show all child products automatically in the same categories as the parent products.
