Wix Stores Request: Filtering Products by Custom Attributes
Collecting votes
Currently, customers can filter products in a gallery or in the Category page by category, price or product options. It's not possible to add tags or custom attributes to products and use them as filters.
Workaround:
As a workaround you can create custom filters without creating product options. Learn how to create custom filters.
We are always working to update and improve our products, and your feedback is greatly appreciated.
