Sortable clone helper not working
- by Jeremy Seekamp
Maybe I don't understand how clone works with sortable, but here is what I would like to do. 
When sorting an item I would like a clone of the item I am dragging remain until I stop drop the item in its new position.
Here's the code:
<html>
<head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.2/jquery-ui.min.js"></script>
    <style type="text/css">
        .sort { width: 150px; }
        .ui-state-highlight { background-color: #000; height:2px; }
    </style>
</head>
<body>
    <div>
        <ul class="sort">
            <li>Item 1</li>
            <li>Item 2</li>
            <li>Item 3</li>
            <li>Item 4</li>
        </ul>
    </div>
    <script type="text/javascript">
        $(function() {
            $('.sort').sortable({
                helper: 'clone',
                placeholder: 'ui-state-highlight',
                opacity: '.5'
            })
        })
    </script>
</body>
</html>
Thanks in advance for the help!
