Thank you for your answer, I realized my goal - now I have a filter on the city. I just created an additional field and fill it in manually. But it would be very cool if such dependencies can be set to fields. Not only the filter of goods by the manufacturer, which operates in a certain city. But and other dependence.
But why I wrote the previous post. The fact is that the site displays the changes a significant time after such changes have been made to the system. It's like it's a cache, although it's disabled in Joomla.
I also noticed that the template files were in another folder, not like before /templates/ja_brickstore/css and /templates/ja_brickstore/local/css - only in this template, or now have all the templates?
