I want to make Sortable Tree with Sortable AF.

I found a good example. This is kind of what I have in mind.

https://github.com/ahamed/treeSortable

I'm trying to incorporate Tree structure into this Component but for now it can be a bit hard. 

I wonder if it is possible..    

I already know about other Forge components (ZTree , Gtree and stuff)  but they don't have save function. They can drag and drop but can't save reorder of  the list in database.

Actualy, this Component (Sortable AF)  already has the function to save reorder of list in database. So I'm asking if we can add Tree Structure to this.. 

Are you familiar with this component?  I'd like you to give me any good clue.

Best Regards,
