It seems like you're describing a process of creating a link within a post that filters content based on two criteria: the subdivision (comuna) and the post type. The link is constructed using a dynamic widget to capture the comuna type, and manually adding the post type. The structure of the link before and after the modification is explained, and there's a mention of the option to filter only by the parent subdivision (comuna) using a query and a post listing.

Before: https:/web.cl/turismo/filtro/comuna-turismo:

"here goes the dynamic comuna ID"

After: ;tipo-turismo:122/

https:/web.cl/turismo/filtro/comuna-turismo:  "here goes the dynamic comuna ID" After: ;tipo-turismo:122/

If you only need it to filter by the parent subdivision, you should use a query and add a post listing to display only the parent subdivisions.
