DW support asked me to create this thread to get some informtaion about a new feature in version 8.5.1.3.
I have no information about the name of this feature, but you should be able to remove groups from the navigation if it's not contain any products and/or all the subgrups is emty.
I need to know how it works, in a solution I alter the productlist in ProductListCollectionProvider so a question would be, does this feature reflect changes in the ProductListCollectionProvider?
