I have a custom post type with a custom taxonomy (to show some "best practice" examples on my website). On the single-post-page (single-bestpractice.php) I wanted to show all the terms (categories) like this:

Parent: Child, Child, Child

I tried this code:

$customPostTaxonomies = get_object_taxonomies('bestpractice');
if (count($customPostTaxonomies) > 0) {
    foreach ($customPostTaxonomies as $tax) {
        $args = array(
            'orderby' => 'name',
            'show_count' => 0,
            'pad_counts' => 0,
            'hierarchical' => 1,
            'taxonomy' => $tax,
            'title_li' => ''
        wp_list_categories( $args );

which outputs:

Child, Child, Parent, Child,

…so, is there a way to sort it by parent/child and make the parent one start with a ":" and remove the "," of the last child?

thanx, Jochen

You might like to follow this post as well as it appears to be essentially the same... Display the Terms from a Custom Taxonomy Assigned to a Post(inside the loop) in Hierarchial Order
