Eh, your question isn’t very clear. Pinned folders sure works just as well in dual as in single folder view. I don’t understand why you talk specifically about Dual view, because obviously you can pin folders in any lister view where you see folders.
But if your purpose is to keep pinned folders in view even when you scroll down, this can be done by dynamic buttons in a toolbar - see Script to show "pinned folders" permanently (while scrolling down)
