is it attributes or variation?

Hello,

If the product comes in different materials, you should use Attributes and Variations.

Go to Products > Attributes to create a global “Material” attribute and add the material values

Then, edit the product and add this attribute.

Enable “Used for variations” and go to the Variations tab to create each variation based on material.

This way, customers can select the material they want on the product page.

Please follow this guide on how to set it: https://woocommerce.com/document/variable-product/

Best Regards,
