Drag event (e.g. to expand an item on hover)

[v1r0x]

First of all: Thanks for this component, it's nice! 🎉

I need the possibility to open items on hover.
As stated in the title I want to expand an item if it is hovered by another item (another item is dragged onto this item). I tried to achieve this using the item-drag-start and item-drag-end events (to set a dragging flag) and the mouseover event in item-events to check the dragging flag and expand the hovered item if dragging = true. But the mouseover event is not fired, since the dragged element is to top-most element.
Would it be possible to add a drag event or is there any other solution I don't see? :)
