I can't drop a cloned image. But this works when I comment the helper:"clone"
option.
$(document).ready(function(){
$("#drag").draggable({
helper:"clone",
revert:"invalid"
});
$("#table4").droppable();
});
the helper is only for visuals.
if you want to clone the image and drop it .. try something like that:
$("#table4").droppable({
accept: "#page",
tolerance: "touch",
drop: function (event, ui) {
ui.draggable.clone().appendTo(this);
}
});
