				$("#m3d").hide();
				
				$("#m1").click(function(){					
					$("#m1d").show();
					$("#m2d").hide();
					$("#m3d").hide();
				  });
				$("#m2").click(function(){					
					$("#m1d").hide();

				  });
				$("#m3").click(function(){					
					$("#m1d").hide();
					$("#m2d").hide();
					$("#m3d").show();
				  });
			});
		</script>
		
		<style type="text/css">
			.mainmune{
				text-align:center;

	<body>
		<table border="0" width="450px" removed="#787878" cellspacing="1" cellpadding="0">
			<tr id="m1" class="mainmune">
				<td>Menu 1</td>
			</tr>
			<tr id="m1d" class="submune">

				</br></td>				
			</tr>
			<tr id="m2" class="mainmune">
				<td>Menu 2</td>
			</tr>
			<tr id="m2d" class="submune">
				<td>
					Sub Menu 3<br>
					Sub Menu 4

			</tr>
			<tr id="m3" class="mainmune">
