This is also how to use Sitefinity 6 to show a product menu and a product on the same page. In other words if you have two controls on the same page, one is a product list widget and the other is a single product detail view widget.
A typical menu and detail relationship.
Is there a comprehensive reference to the Advanced configuration options for widgets? I have seen references to Microsoft documentation for these, maybe they are a standard solution.
In any case thank you for answering this question.
