[Vuejs]-Is there a way to get the position of the "ghost image" when dragging an element

the position of the ghost image will be the same as the position of the pointer / mouse pointer. Since you are using jQuery, these coordinates (position) can be acquired this way:

$("body").mousemove(function(e) {
    console.log('position of ghost image: ' + e.pageX + ', ' + e.pageY;
})
