We have the ability to create custom hierarchical taxonomy terms, and this gives us some amazing CMS capabilities, but, I have not been able to find any way to list the terms from a custom taxonomy that is hierarchical on a single post while maintaining the hierarchical structure.
It would be great if either wp_list_categories ( since this function can already be used to create a list of hierarchical taxonomy terms and provides a link ) included the ability to only list terms assigned to the current post ... or if get_the_terms_list would include the ability to maintain the hierarchical structure the way that wp_list_categories does.
I'm going nuts at the moment because I have custom hierarchical taxonomies that are up to 4 levels deep, with terms that in many instances only make sense in relation to their parent.
I need to list the terms assigned to a post in the sidebar on the single view. As is, I can either list ALL terms with a great hierarchical structure, but, no relevance to the current post ( wp_list_categories ), or with great relevance to the current post, but, the list is an incomprehensible mess ( get_the_terms_list ).
It would be awesome to see one of the above, or both, extended to allow for this capability.
