I'd like the module to not show any product if there are no more related items which haven't already been added to the cart. How can I achieve this?

Thanks in advance.")* Hi, I agree that the system could be improved to avoid referencing such products in the module as it doesn't make sense in most cases. Try adding the line: Code: $filters[] = 'b.product_id NOT IN ('.implode(',',$mainIds).')'; after the line: Code: $filters[] = 'b.product_id IN ('.$ids.')'; in the file components/com_hikashop/views/product/view.html.php That should do it. Let us know how it goes so that we can include the change for the next version of HikaShop.
