Is there a way to implement this?
Selecting various list elements and drag them to another list
It is not suported by sortable.js nor by vue.draggable.
I almost did it...
So, in my application, on click over the draggable item, I set a property isSelected = true.
Then I have another draggable with a single button inside: Clone Selected.
This draggable has the hook clone attached, so I can return the items that are selected (isSelected === true) as an array of objects, instead of a single one.
I can't seem to find a way to catch that array "onDrop", as the data object is not in the event.
Not sure I make sense.
@igasparetto Why no jsFiddle for this? would have been super duper helpful.

As of May 2019, the "next version branch" of vue-draggable is going to support dragging of multiple elements at the same time -> https://github.com/SortableJS/Sortable/blob/next-version/README.md
