Works like a charm. Thanks so much!
Thanks Marco for your reply.
I found that when i used the “show” parameter, the post (containing the desired tag) and the top category appear.
To be absolutely clear, i’m trying to show only subcategories which contain posts tagged with my specific keyword. I’m not looking to display the posts.
The opposite remains true: i’m trying to hide only subcategories which contain posts not tagged with my specific keyword.
Appreciate your help greatly, Thanks!
