jQuery problem with navigation

Hey there,

I’ve been having a problem some while now with a plugin i’ve used for a vertical navigation menu on this website.

i’ve modified the plugin jquery vertical accordion menu to a certain extend because what i was trying to achieve is the “menu state” would be remembered accross navigating through the different pages.
This seemed impossible because every time you would navigate to a different page the whole website would refresh resetting the menu state. So that’s why i used cookies.

But sometimes this error appears,.. leaving to submenu’s from different categories overlapping each other…I’m not sure what to do and also if this error is based on browser type.. Maybe it could be the use of taxonomies in wordpress or some sort of conflict between permalinks?

On each “archive” page i get the posts from a certain category doing this in php `<?php
$expl = explode(‘/’, $_SERVER[‘REQUEST_URI’]);
if(isset($expl[3])){
query_posts( array (
‘post_type’ => ‘portfolio’,
‘portfolio_category’ => mysql_real_escape_string($expl[2]),
‘showposts’ => 1,
‘taxonomy’=>’category’,
‘orderby’ => ‘date’,
‘order’ => ‘DESC’
));
} else {
query_posts( array (
‘post_type’ => ‘portfolio’,
‘showposts’ => 1,
‘taxonomy’=>’category’,
‘orderby’ => ‘date’,
‘order’ => ‘DESC’
));
}
?>`

Could this be a problem?

thanks a lot for any help!!!!
