Hello,
To set up “Search by Material” and “Search by Color,” go to Products > Attributes, create the attributes (e.g., Material, Color), add terms, and assign them to your products. Then, use the “Woodmart WooCommerce layered nav” widget to enable filtering on the shop page.
For the categories, Go to Products > Categories and create a parent category (Material) and then add subcategories under it (Crystal).
If you have any questions, feel free to contact us.
Best Regards,
