javascript - JQueryUI: drop within container, append and revert -


i got stuck jqueryui. specifically, have following html snipped:

<div class="from">  <div class"item">item 1</div>  <div class"item">item 2</div>  <div class"item">item 3</div> </div>  <div class="to"></div>

now want make items draggable , droppable on "to" box via jqueryui library. therefore, use javascript snippet:

$('.item').draggable({   revert: true });  $('.to').droppable({   drop: function(event, ui) {     ui.draggable.appendto(this);   } });

while works far result concerned, animation handling 'revert' doesn't behave want to. problem dragging implemented setting "position: relative" , changing 'top' , 'left' css properties. item attached new container (which happens before revert animation), jumps new position because it's positioned relatively new container. revert animation starts @ new position.

is there way can have smooth revert animation after attaching item new container? perhaps going wrong way, please don't hesitate suggest different approach.

i have been trying recalculate css left , top properties based on new containers absolute position, of course works first dropped item, second 1 additionally have consider first item's position.

thanks.
