[REACT] Replace Drag&Drop Component

I need help with reworking a Page in my Webtool.
At the moment we are using "sortable-tree" (https://github.com/frontend-collective/react-sortable-tree)
but i would like to change to something more nice, like:

1. react-sortful (https://github.com/jagaapple/react-sortful)
or
2. react-beautiful-dnd (https://github.com/atlassian/react-beautiful-dnd)

sotable-tree behaves not very nice when it comes to change the position of List-Items.
Problem is, that i have a quite complicated "auto group & sort" functionality.

please check out the Code and let me know if its doable to change the dnd component but keep the auto group& sort functionality.

thx!

ps: if you read through all this, write "geranimo" as your first word in your proposal. thx!!
