	<div>Item1</div>
	<div>Item2</div>
	<div>Item3</div>
	<div>Item4</div>
</div>
<div class="easyui-dialog" style="width:600px;height:300px;padding:20px">
	<button class="easyui-linkbutton" onclick="showmenu(event)">Show Menu</button>
</div>
<script>
	function showmenu(e){
		e.preventDefault();
		$('#picMenu').menu('show', {left:e.pageX,top:e.pageY})
	}
</script>
