Windows 10 Taskbar Folders

I am looking for a utility to be able to add folders to the Windows 10 Taskbar that when clicked on pops up from the Taskbar to give you a choice of the contents to launch the program or file etc. I have found a way to tweak the Taskbar to open a folder, like you would when launching Windows Explorer, but that is not what I want. I do not like having a multiple line Taskbar and would like to group my stuff together to make more room on my Taskbar. Any suggestions? Does such an app exist from Stardock or elsewhere?

Thx

Bob
