want to copy dragable element. But my code is cutting the element and pasting it on the dropzone

I am using this to drag and drop element
$ ( ".drag-able" ). draggable ({
appendTo: "body" ,
cursor: "move" ,
helper: "clone" ,
revert: "valid"
});

$ ( ".drop-able" ). droppable ({
tolerance: 'pointer' ,
drop : function (event, ui) {
$ ( this ). append ( $ ( ui . draggable ));
},
});

but it disappearing the original element. I want to drag the element to a new position by keeping the original one on its position. Is this possible?
