Horizontal and vertical combined example

[iConic21]

Hi, After following your Docs and some example for hours,
I did manage to get single dnd working, but I wanted to create nested dnd.

I tried to use one of your examples and combine the two https://codesandbox.io/s/8l826881n9
I'm not sure what I'm doing wrong based on the docs it should work (I think?)

Thanks.
