I am using a slide menu from dhtmlgoodies. in general it works great. but when you click on a new primary menu item the page jumps. Thank you in advance for your help.
my nav:
//prim links followed by secondary links
$sql_primLinks = "SELECT id, title, link FROM primaryNav WHERE hidden = '0' ORDER BY orderLinks ASC";
$res_primLinks = mysql_query($sql_primLinks);
$num_primLinks = mysql_num_rows($res_primLinks);
for($p=0;$p<$num_primLinks;++$p){
$id_primLinks = mysql_result($res_primLinks,$p,0);
$title_primLinks = mysql_result($res_primLinks,$p,1);
$link_primLinks = mysql_result($res_primLinks,$p,2);
echo '<li>';
echo '<a href="'.$link_primLinks.'?pageName='.$title_primLinks.'" >> '.$title_primLinks.'</a>';
//are there secondary links?
$sql_secLinks = "SELECT id, title, link FROM secondaryNav WHERE hidden = '0' AND primId = '".$id_primLinks."' ORDER BY orderLinks ASC";
$res_secLinks = mysql_query($sql_secLinks);
$num_secLinks = mysql_num_rows($res_secLinks);
if($num_secLinks > '0'){
echo '<ul>';
for($s=0;$s<$num_secLinks;++$s){
$id_secLinks = mysql_result($res_secLinks,$s,0);
$title_secLinks = mysql_result($res_secLinks,$s,1);
$link_secLinks = mysql_result($res_secLinks,$s,2);
//begin secondary links
echo '<li>';
echo '<a href="'.$link_secLinks.'?primary_pageName='.$title_primLinks.'&pageName='.$title_secLinks.'&id='.$id_secLinks.'&primId='.$id_primLinks.'" >'.$title_secLinks.'</a>';
echo '</li>';
}
echo '</ul>';
}
echo '</li>';
}


the js:
var expandFirstItemAutomatically = false; // Expand first menu item automatically ?
var initMenuIdToExpand = false; // Id of menu item that should be initially expanded. the id is defined in the <li> tag.
