   Hi there,
   I would like to know how can display a multilevel custom taxonomy menu that expands depending of the current parent / children taxonomy that is selected.

   Example:
   -------------------
   Taxonomy navigation
   - taxonomy 1
   - taxonomy 2
   - taxonomy 3
   -------------------

   When I click the "taxonomy 1" link, the page of that taxonomy loads and the "Taxonomy navigation" list now also shows the children taxonomies of taxonomy 1 which becomes bold:

   -------------------
   Taxonomy navigation
   - taxonomy 1 [selected]
   -- taxonomy 1.1
   -- taxonomy 1.2
   -- taxonomy 1.3
   - taxonomy 2
   - taxonomy 3
   -------------------

   After that, when I click on "taxonomy 1.1" it should look like this:

   -------------------
   Taxonomy navigation
   - taxonomy 1
   -- taxonomy 1.1 [selected]
   -- taxonomy 1.2
   -- taxonomy 1.3
   - taxonomy 2
   - taxonomy 3
   -------------------

   So, it should work as a hierarchical menu and display the active state of the current taxonomy.

   Thanks!

   Anyone has any clue?
   I have found a plugin that seems to do what I want to do, but the plugin is for "Pages" only :

   ok guys some updates: I played a little with the code and here is what I come up with. Now the categories (taxonomies) show in a hierarchic way but the list only shows up in the post page and index page. In the archive page it outputs "no category".

   <?php 
   
   $taxonomy     = 'mytaxonomy';
   $orderby      = 'id';
   $show_count   = 1;      // 1 for yes, 0 for no
   $pad_counts   = 0;      // 1 for yes, 0 for no
   $hierarchical = 1;      // 1 for yes, 0 for no
   $title        = '';
   $current_tax = get_query_var('mytaxonomy');
   $hide_empty = 0;
   
   $args = array(
     'taxonomy'     => $taxonomy,
     'orderby'      => $orderby,
     'show_count'   => $show_count,
     'pad_counts'   => $pad_counts,
     'hierarchical' => $hierarchical,
     'title_li'     => $title,
     'child_of'  => $current_tax,
    'hide_empty'  => $hide_empty,
   'current_category'   => 0
   );
   ?>
   <ul>
   <?php wp_list_categories( $args ); ?>
   </ul>
