IE8必须增加子菜单，隐藏
复制代码 代码如下:
<link href="../css/right_menu.css" rel="stylesheet" type="text/css">
<DIV class=c_l>
<DIV class=menu>
<UL>
<?php
mysql_select_db($database_lr, $lr);
$query = mysql_query("SELECT * FROM bigclass order by sort");
while($row=mysql_fetch_array($query))
{
$bigclassid=$row['bigclassid'];
$bigclassname_leftmenu=$row['bigclassname'];
if ($htmlname==1){
$bigclass_htmlname_leftmenu=$bigclassname_leftmenu;//大类名称
$bigclass_htmlname_leftmenu=tihuan($bigclass_htmlname_leftmenu);
}
if ($htmlname==0){
$bigclass_htmlname_leftmenu=$bigclassid;
}
?>
<LI <?php
//<!--判断是否有小类别-->
mysql_select_db($database_lr, $lr);
$query_num="select count(*) from smallclass where bigclassid='$bigclassid'";
$rs_num=mysql_query($query_num);
$myrow_num = @mysql_fetch_array($rs_num);
$smallclass_num=$myrow_num[0];
if ($smallclass_num>0){
echo "id=arrow";
}
?
<a href="<?php echo "../".$htmlcatalogue."".$bigclass_htmlname_leftmenu.".html"?>" class="bigclasslink" > <?php echo $row['bigclassname']?><!--[if IE 7]> <!--></a><!--<![endif]--><!--[if lte IE 6]><table><tr><td><![endif]-->
<?php
mysql_select_db($database_lr, $lr);
$query_small = mysql_query("SELECT * FROM smallclass where bigclassid='$bigclassid' order by sort");
if ($smallclass_num==0)
{
echo "<ul style='display:none'><LI><A title=
href=></A> </LI></ul>";
}
else
{
?> <UL>
<?php
while($rs=mysql_fetch_array($query_small))
{
$smallclassid_small_leftmenu=$rs['smallclassid'];
$smallclassname_small=$rs['smallclassname'];//小类名称
if ($htmlname==1){
$smallclass_htmlname=$smallclassname_small;
$smallclass_htmlname= tihuan($smallclass_htmlname);
}
if ($htmlname==0){
$smallclass_htmlname=$smallclassid_small_leftmenu;
}

* HTML .menu A:hover {
POSITION: relative
}
.menu LI:hover {
POSITION: relative
}
.menu UL :hover UL {
TOP: -1px
}
.menu UL LI:hover > A {
BACKGROUND: #eee; POSITION: relative; TEXT-DECORATION: none
}
.menu UL LI UL LI:hover > A {
BORDER-TOP-STYLE: none; BORDER-RIGHT-STYLE: none; BORDER-LEFT-STYLE: none; POSITION: relative; TOP: 0px; BORDER-BOTTOM-STYLE: none
}

其中menu UL UL的left或者right控制向右或者向左显示子菜单
