Assuming you're in the Library Module, collapse all the options in the left-side Navigator. That is, the arrows will point right rather than down. Just click on the arrow to collapse / expand. Then, right click in the open space created within the panel. You'll get a menu with what can be displayed. Click on Folders to restore their display.
