Hidden menu items are items from the menu that appear on the terminal screen only after entering a code (usually these are promotional menu items).
The Hidden Menu Items selector page is created and filled with menu items in the standard way.
But unlike regular selector pages, the Hidden Menu Items page is not included in other selectors. Thus, the page itself and the items included in it are not displayed on the kiosk screen when creating an order. They can only be added to an order after entering their code.
