While creating the application I encountered a problem.
Indeed, I cannot insert different submenus between the menus (each menu has the same submenu, but that is not my wish), I would like each menu to be its own submenu.
I made a “relation” between my columns in order to obtain different submenus, but nothing is displayed, or is displayed in each menu. The “inline list” option does not exist in my software.
How can I create different submenus?
