Big Thanks, it was that!
Another question:
How can I implement a filter like you have in:
https://demo.products-filter.com/
I mean, do I need any kind of plugin.
I’ve tried to add the attribute directly to mi product via Editing Product and adding an Attribute in the Product Data fields, but nothing happens in the filter.
I want to create a shop to sell clothes with a filter for sizes and colors.
What do I exactly need, apart from ‘WOOF – Products Filter for WooCommerce’
Thanks again!
