How can a user add a new "Group by" in a list view? By user I mean someone who is not a programmer or admin. If the admin can do it then how?
For example, when viewing the list of products, how can a user add "Group by manufacturer". This is not currently an option under "Group by".
This is not a question about filters. There is a way to create an advanced filter and save it. I'm asking for the same functionality but for "Group by".
