Go to the list menu (when the list is open, click the arrow in upper right corner below profile icon), then choose Duplicate. This creates a new copy of the list without any rows added (even if there already are rows of data in the list, the copy will be empty).

I have a format for a list that I want to use for multiple sets of list contents. At the moment there is no content in any of the fields. How can I make multiple copies of this same format?
