Sean Callahan comments:

This didn't work...it just shows every single category.

Jerson Baguio comments:

Try to replace the code in themes/thesis_182/lib/functions/nav_menu.php

i think its in line 56

with this one


if ($thesis_site->nav['categories']){
if($post->post_parent)
$children = wp_list_categories("title_li=&child_of=".$post->post_parent."&echo=0");
else
$children = wp_list_categories("title_li=&child_of=".$post->ID."&echo=0");
if ($children) { ?>



<?php echo $children; ?>


<?php
}

}


and replace the #nav to #menu from css i pasted above

Sean Callahan comments:

Is there a way to do it without hacking up the core?

rename custom-sample folder to custom and the code below in your custom_functions.php found in /thesis_182/custom

Jerson Baguio comments:

Hi sean,
try the custom functions i created it should do the work.

Sean Callahan comments:

I put it in there and it still doesn't work...in fact none of the categories show up with that code. I was supposed to use the CSS from above, correct?

Jerson Baguio comments:

Yes but instead of #nav use #menu like below

* {

margin:0;

padding:0

}



#menu {

background:#577da2;

border-bottom:1px solid #FFF;

height:32px;

}



#menu li {

margin-right:25px;

}



#menu li, #subnav li {

float:left;

list-style:none

}



#menu a, #menu a:visited {

color:#FFF;

text-decoration:none;

font-weight:bold

}



#menu a:hover, #menu a:active,

li.current_page_parent a,

li.current_page_parent a:visited,

#menu li.current_page_item a,

#menu li.current_page_item a:visited

{

background:#295887

}



#subnav {

background:#e6eef7;

border-top:2px solid #577da2;

border-bottom:2px solid #cad8e6;

height:28px;

}



#subnav li {

border-right:1px solid #295887;

padding:0 7px;

}



#subnav a, #subnav a:visited {

color:#295887;

text-decoration:none;

font-weight:bold

}



#subnav a:hover, #subnav a:active,

#subnav li.current_page_item a,

#subnav li.current_page_item a:visited {

text-decoration:underline

}

Yes i tested it with WP 3.0+ i guess it was 3.2 the latest one i installed a new Installation just to test the thesis_182 theme.

One issue i saw on you side it must be the CSS file.

from #nav to #menu since the Div id of thesis_182 is menu not nav..

If you want a help to set it up to your server you can create me a test account
on that site and just delete the account when the menu is done.
This task may out of time now so you can contact me via pm or in my email @ iamjerson[at]gmail[dot]com

thanks
