Comment(by mfields):

 Replying to [comment:1 nacin]:
 > wp_dropdown_categories() only returns HTML. I imagine you're referring
 to the default widget in particular?

 I actually just finished up a plugin [http://wordpress.mfields.org/2010
 /screenshot-of-the-new-taxonomy-widget-plugin/] that is a fork of the
 categories widget. It would have been simple to create except for the bug
 in wp_dropdown_categories(). To fix the bug, I had to rewrite
 functionality of wp_dropdown_categories(), walk_category_dropdown_tree()
 and the Walker_CategoryDropdown class.

 The reported bug is in the html outputed by the Walker_CategoryDropdown
 class mainly this line:


 {{{
 $output .= "\t<option class=\"level-$depth\"
 value=\"".$category->term_id."\"";
 }}}

 Which works great for categories by does not work at all for other
 taxonomies.

 /?cat=14

 /?tag=my-tag-name

 /?taxonomy=my-taxonomy-term-name

 Categories are the only ''post taxonomy'' queried by id number, all others
 use slug. I reported this as a bug because I was looking through core and
 saw that wp_dropdown_categories() now allows the user to pass ''taxonomy''
 as a key in the $args array.

 This would be awesome to have fixed in core. Hopefully I have explained
 the issues well enough. You can see the changes that I needed to make to
 get my plugin functioning correctly here

 Thanks for your attention!
