@morganpizzini Can you add some documentation about it in README.md?

[RomanBurunkov]

Consider updated README, I'm not quite sure that code:

            var itemMoveIn = this.dragEl.find(opt.itemNodeName).data('moveIn');
            var listNo = this.pointEl.closest('.dd-list').data('listNo');
            if (itemMoveIn !== listNo) {
                return;
            }

works properly with attributes: 'data-move-in' and 'data-list-no'.
It looks like attributes should be 'data-moveIn' and 'data-listNo'.

It's a bit confusing for me, but it works =)

ops yes, i think i press some strange shortcuts who delete "-" and uppercase the first char after 😄 sorry my bad, i'm going to fix it

[RomanBurunkov]

@morganpizzini , that's, ok =)

But check my update to previous comment....it works =)))
Despite, fixing it also works and also more clear.

@morganpizzini Can you check this demo: https://jsfiddle.net/s5yt9mc4/6/

I'm still able to do this:

this is correct?

[morganpizzini]

Yes of course,
data-list-no inside "Item 6" must have 3 as index and not 2, same for data-move-in inside
