Tag Groups Premium is able to show tags and groups among product attributes. This feature heavily depends on the template and was tested with the default and other themes. It therefore may not work with all themes.
Follow these steps:
- Go to the Taxonomies settings and enable “Product tags”.
- Go to the Back End settings, Meta Box tab, and enable the Meta Box for “Product tags”.
- Go to the Front End settings, WooCommerce tab and activate “Display tag groups with WooCommerce attributes”.
- Go to a product and use the Meta Box to add tags in groups.
