Hi Ernest,
Brand is an attribute of products in woocommerce.
If I don’t group, I can see the attribute “Brand” as the first result between four.
If I group, as it’s not a category nor a product nor a post type, it disappears.
I don’t if there is a way to post filter the results. I saw an example with the categories titles in the results titles with the hook asp_pagepost_results.
I thoughabout a solution with a hook: parsing the results and hash the url of the link of each result in order to add a line of the type of results when I see different groups (categories, attributes, products, …).
Thanks for your reply.
Have a nice day,
Bastien
