Return ValueThe unpinned stairs element.
If the story at the given level is in a group, it will separate an individual stairs element from the group with "unpinned" status. Changes you make to the returned stairs element will not affect any other stairs. If the story of stairs is already an individual stairs element, the status will be changed to "unpinned".
