Hi XStore team,
We are building a WooCommerce store using XStore and have a question about the built-in filter widget.
We are thinking to register a custom taxonomy called product_application (rewrite slug: solutions) on the product post type via functions.php. We need the XStore filter widget to use this taxonomy as a filter source on category and subcategory archive pages — the same way it handles etheme_brands and WooCommerce global attributes.
Specifically we need to confirm:
1. Can the XStore filter widget be configured to read from a custom taxonomy we registered ourselves (product_application), not just built-in taxonomies like etheme_brands?
(1. Does the XStore filter widget automatically pick up custom taxonomies registered via functions.php, or does it only read its own built-in ones (etheme_brands, product_cat)?)
2. If yes, how do we add it as a filter source — is it available in the filter widget settings automatically once the taxonomy is registered, or does it require additional configuration?
3. Does the filter widget support showing only relevant attribute values based on the current category or subcategory context (i.e. on /products/pumps/submersible-well-pumps/ it only shows brands and attributes that exist within that subcategory)?
If the built-in filter cannot support a custom taxonomy as a filter source, please let us know whether FacetWP or WOOF is the recommended third-party solution for this use case with XStore.
Thank you.
