Hello,

Yes, that is right. Product categories filter (you need to add a Product category filter to the shop page widget area) sort out products by category, regardless of attribute filters.

Woocommerce Attribute filter by default sorts out the products regardless of the product category.

You can add WoodMart filters and set the category where they are displayed, in this case, the filter will sort out the products within the category.

Please check this manual: https://xtemos.com/docs-topic/widgets-and-sidebars/

If you have any questions please feel free to contact us.

Best Regards
