I'm a bit confused. You say you want to remove the toolbar from the list, but the only way to do that is to uncheck it. This of course will also remove the toolbar from the taskbar.
If you are just wanting to have a pinned folder on the taskbar, but not as a toolbar, then you could use OPTION ONE in the tutorial below to do so.
Taskbar - Pin or Unpin a Folder
Hope this helps.
