Mobile support

[nscarcella]

Hi Chris,

I can't seem to make the library work for mobile. Dragging is fine in most devices I tried, but it seems like no event gets fired once I drop a draggable on a droppable.
I was preparing a code example, but seems like the demo site examples don't work for me either, so you could check from there.

Is there any workaround to make the events work (I only need the onDrop event) or perhaps some extra configuration (like the pointer-events: none) that would work for mobile?

Thanks.
