@tbhesh: I just check in that URL and see that you have successfully added “Product Category” widget there. So, now you can add other widgets in the same place where you have added that product widget.
Actually I’ve found that only the text-based widgets work. Categories works none of the filters do. When I add filter widgets to one of the optional sidebars OR the WC sidebar settings they don’t render. Same some of the other widgets. In the sidebar on that page are currently 4 widgets, all WC filters, that do not display.
These same filters DO display in the footer, however.
