Hi Paolo,
I have been testing your suggestion but it does not quite work for what I want to achieve.
The first part, the “Near Me” button is fine, but the second part, that implies a lot of “Popular post widgets” to be able to show all CPTs and all their Categories in the location page, is not what I want to achieve, since I would like to able to show only the listings of the Category selected by the user from a default set CPT.
I thought about having several location pages to show at least only one CPT per location page, but I understand that this is not possible, since there is only one location page.
Now I am thinking about some way to allow the user to select a single “Popular post widget” to view from the many that could be present in the location page, but I do not see a way to do it.
So I think a I am going back to the idea of trying to find a good developer but, since several months ago I posted a couple of requests in your developers forum and I did not get any reply, I guess I should look elsewhere.
Thank you very much once again for your attention, willingness, help and patience.
Best regards.
