Current-cat in single post type

Hi guys,

Wassup? I tried to find the solution of my problem but I can’t find it anywhere… I hope someone will be a wordpress master to help me ??

here is my problem:

I have a custom post type called “produits” using taxonomy for this post type called “filtres”. To display the taxonomy list I use this code:

$orderby = 'name';
$show_count = 0; // 1 for yes, 0 for no
$pad_counts = 0; // 1 for yes, 0 for no
$hierarchical = 1; // 1 for yes, 0 for no
$taxonomy = 'filtres';
$title = '';

$args = array(
  'orderby' => $orderby,
  'show_count' => $show_count,
  'pad_counts' => $pad_counts,
  'hierarchical' => $hierarchical,
  'taxonomy' => $taxonomy,
  'title_li' => $title
);
?>

<?php
wp_list_categories($args);
?>

Everything works fine! I need to highlight the current-cat so I used the CSS to do that and it works! Going in the taxonomy, highlighting work too ! The problem is when I visit a single post of my post type, the current-cat doesn’t appear in the <li > < /li>

Does anyone know how to add the “current-cat” class to my wp_list_categories in a single post type?

Thanks a lot guys, you’ll make my day ! ??

BTW HAPPY NEW YEAR !
