Included sortables. Bug with elements positions in IE7.

It must be sortable tree with saving parent/child element status. In all another browsers it works correct.

<style>
.treeChild{
margin-left:20px;
}
</style>
<div id="tree">
<ul class="parent">
	<li class="treeParent">parent 1</li>
	<li class="treeChild">child 1_1</li>
	<li class="treeChild">child 1_2</li>
</ul>

<ul class="parent">
	<li class="treeParent">parent 2</li>
	<li class="treeChild">child 2_1</li>
	<li class="treeChild">child 2_2</li>
</ul>
</div>


<script language="JavaScript" type="text/javascript">
	  $( "#tree" ).sortable
			(
				{
				connectWith: "#tree",
				items: 'ul'
				}
			);

		$( ".parent" ).sortable
			(
				{
				connectWith: "#tree .parent",
				items: 'li:not(.treeParent)'
				}
			);
</script>
