Mình code lại bằng PHP + MySQL bạn tham khảo nhé
Code create table + insert sample data:
Code:
Table structure for table `menu`
CREATE TABLE IF NOT EXISTS `menu` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(30) CHARACTER SET utf8 COLLATE utf8_unicode_ci DEFAULT NULL,
`parentid` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=9 ;
Dumping data for table `menu`
INSERT INTO `menu` (`id`, `name`, `parentid`) VALUES
(1, 'a', 0),
(2, 'b', 4),
(3, 'c', 4),
(4, 'd', 1),
(5, 'e', 1),
(6, 'f', 0),
(7, 'g', 6),
(8, 'h', 6);

mysql_select_db("testmenu",$conn);
$mn = "";
function menu($id)
{
global $mn;
$sql = "select * from menu where parentid=".$id;
Trang 2$query = mysql_query($sql);
while($row = mysql_fetch_assoc($query))
{
$mn.= "<li><a href='#'>".$row['name']."</a><ul>";
menu($row['id']);
$mn.= "</ul></li>";
}
}
menu( );
$mn = str_replace("<ul></ul>", "", $mn);
echo '<div id="wrapper"><div id="mainNav"><h1>Main Menu</h1><ul>'
$mn.'</ul></div></div>';
?>
</body>
</html>
code file styles.css

/* CSS Document */
*{margin:0; padding:0;}
#wrapper{
width: 500px;
margin: 40px auto;
line-height: 2em;
font-size: 12px;

#mainNav ul li:hover ul li ul {
display: none;
}
#mainNav ul li ul li:hover ul {
display: block;

Bổ sung thêm code bằng asp + sql server
Code create database
Code:
CREATE DATABASE testmenu
GO
USE testmenu
GO
CREATE TABLE [menu](
[id] INT not null,
[name] NVARCHAR(50) not null,
[parentid] INT not null
)
GO
INSERT INTO [menu]([id],[name],[parentid]) VALUES (1, 'a', 0) INSERT INTO [menu]([id],[name],[parentid]) VALUES (2, 'b', 4) INSERT INTO [menu]([id],[name],[parentid]) VALUES (3, 'c', 4) INSERT INTO [menu]([id],[name],[parentid]) VALUES (4, 'd', 1) INSERT INTO [menu]([id],[name],[parentid]) VALUES (5, 'e', 1) INSERT INTO [menu]([id],[name],[parentid]) VALUES (6, 'f', 0) INSERT INTO [menu]([id],[name],[parentid]) VALUES (7, 'g', 6) INSERT INTO [menu]([id],[name],[parentid]) VALUES (8, 'h', 6) Code file index.asp
