Remove last portal row record
I have a portal that has been build in a previous layout so the items on there are fixed already. However, in the portal, there is always an additional row at the bottom that doesn't contain a record but you can still enter into fields which I'm guessing then creates a new portal record.
How can you get rid of this additional row that isn't wanted? If this can't be done, is there a way to prevent the user from entering data into that row?
