Hi Mehtaz:
We would like to have this feature added also.
I think would be nice to have a dynamic filtering for categorires. Let me put you an example
If you sell Cisco, you could sell routers, swithches or access points, so when you do select category "cisco" would be nice to be able to display / filter Cisco Sub Categories.
When you work with hardware is not easy just combining categories & tags (for ex manufacrurer in tag and categories for type of products) cause could be a mass.
Also we already have the categories and sub-categories at SPPage builder .... not possible to import to the shop ?
Best Regards
