I see what you mean, but our plugin only works per post type.
‘Template’ is the post type, and Elementor chooses to create subpages based on extra arguments in the URL.
Unfortunately, our plugin is not able to recognize these URL params so that’s why it works for all templates.
You could choose to create different column sets in our plugin and easily switch between column sets for the different subcategories for templates. Let me know if you have any further questions.
