Hello,
By default, WooCommerce doesn’t treat product weight as a filterable attribute in widgets.
You need to create a custom product attribute (e.g., Weight) under Products > Attributes.
Add terms like 500g, 1kg, 2kg, etc.
Assign this attribute to each product manually, Then Navigate to Appearance > Widgets > Add the WoodMart WooCommerce layered nav widget in the shop page widget area and choose the attribute “weight”.
This way, your archive page will display a proper filter for weight as expected.
Best Regards,
