Taskbar Toolbar Flyout menu from folders and/or links

I have been doing a lot of searching and haven't been able to figure this out in win7. I have seen some people do this in videos. What I am trying to add a toolbar on the task bar that I would NOT reduce the size to nothing just to get the sub folders to fly out.

An example of this that I have seen is that they added a toolbar of the Computer (all the drives) and all you would have to do is click on C: and a fly out menu of it's contents would fly out from there.

I have been able to accomplish this sorta, I have been able to create the toolbar, but I have to do a ctrl + left click on the C: drive and it would fly out. Is there anything I am missing to get this to work?

Thanks

Ben
