Check the following code:

    <style>
#draggable { width: 150px; height: 150px; padding: 0.5em; }
</style>
<script>
    $(function () {
        $("#draggable").draggable();
    });
</script>



<div class="demo">
<script type="text/javascript"
        src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
    <script type="text/javascript"
        src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.js"></script>
<div id="draggable" class="ui-widget-content" style="cursor:move">
    <p>Drag me around</p>
</div>
