Вы бы код показали...

$(document).ready(function(){
	$(function() {
		$("#list").sortable({ opacity: 0.6, cursor: "move", update: function() {
			var order = $(this).sortable("serialize") + "&action=updateRecordsListings";
			$.post("/index.php", order);
		}
		});
	});
});

используется jquery ui 1.7.1
и собственно jquery

<div class="sites" id="list">

<div id="recordsArray_463" class="box" title="" onmouseout="document.getElementById('2').style.opacity = '0.0';" onmouseover="document.getElementById('2').style.opacity = '0.9';" onclick="location.href='http://allbest.ru';"style="background:black url('./thumbnails/1369328664_2013-05-23-200.jpg');">
    <div class="buttons" id="2">
        <a class="edit_site" href="edit_site.php?id=463">
            <img src="./img/settings3.png" />
        </a>
        <a class="delete_site" href="?category=&deleteSiteId=463">
            <img src="./img/stop_white_2.png"/>
        </a>
    </div>
        <div class="title" style="z-index: 1; position:relative;">Доклады</div>
</div>

</div>
