A question please

[uchoamaster]

checking your documentation, there's a message that it doesn't work in version 2.7.16 of vuejs2, is that correct? because I did some tests with an example code of yours hosted on codepen and it worked... or were you just referring to the table? follow the link to the code and you can test it if you want by changing it to the version I commented on: https://codepen.io/phphe/pen/KRapQm

your example is vueDraggableNestedTree, it is no longer maintained.
