   Does anyone knows how to display terms of a custom taxonomy in a dropdown menu, complete with the post count?

   Thanks in advance.

   Maybe this will work: http://www.shibashake.com/wordpress-theme/expand-the-edit-category-admin-panel

   Hi bedex78,

   You can use this:
   http://codex.wordpress.org/Template_Tags/wp_dropdown_categories

   example:
   <?php wp_dropdown_categories('show_option_none=Select category&show_count=1&orderby=name&echo=1&taxonomy=custom_taxonomy_name');

   I don't really like that one, though, because you are forced to use the taxonomy ID as the value, which, if you are using it for a jumpmenu, can make it difficult to work with custom taxonomy templates

   I just wrote the function below which uses get_terms:
   http://codex.wordpress.org/Function_Reference/get_terms

   It uses the get_terms arguments (see codex link above) by passing them through the $args array.

   Advantages:
   - creates easy to use links to taxonomy templates
   - you can add multiple taxonomies to the dropdown list

   Disadvantages: I haven't figgred out how to add 'count' yet, along with other parameters that wp_dropdown_categories offers.

   <?php
   function get_terms_dropdown($taxonomies, $args){
   	$myterms = get_terms($taxonomies, $args);
   	$output ="<select>";
   	foreach($myterms as $term){
   		$root_url = get_bloginfo('url');
   		$term_taxonomy=$term->taxonomy;
   		$term_slug=$term->slug;
   		$term_name =$term->name;
   		$link = $root_url.'/'.$term_taxonomy.'/'.$term_slug;
   		$output .="<option value='".$link."'>".$term_name."</option>";
   	}
   	$output .="</select>";
   return $output;
   }
   
   $taxonomies = array('custom_taxonomy_name');
   $args = array('orderby'=>'count','hide_empty'=>true);
   echo get_terms_dropdown($taxonomies, $args);
   
   ?>

   Hope this helps!

   Okay, I tried the default code using the wp_dropdown_categories function. Problem is, though, that the links for my the custom taxonomies don't work. The link structure is completly wrong.

   The wp_dropdown_categories function returns links that look like:
   bloginfo(url)/?cat=ID, but the links to the custom taxonomies look actually like bloginfo(url)/?custom_taxonomy_name=slug (I set the rewrite part in functions.php to false).

   When I set 'name' => 'custom_taxonomy_name' for wp_dropdown_categories, at least it replaces the '?cat' part with the correct '?custom_taxonomy_name' part. But instead of the slug, it still uses the ID and that results in a link error then.

   I don't know if this some kind of permalink, rewrite rules or error of the drop-down code for the wp_dropdown_categories function.

   I tried your code, earthmanweb, but while it returns the drop-down, nothing happens upon selecting a value.

   Frustrating so far. So any hints are very welcome.

   You can get term link with get_term_link() - first arg is term id, second taxonomy. So you can replace this:

   $root_url = get_bloginfo('url');
   $term_taxonomy=$term->taxonomy;
   $term_slug=$term->slug;
   $term_name =$term->name;
   $link = $root_url.'/'.$term_taxonomy.'/'.$term_slug;

   With

   $link = get_term_link($term->term_id, $term->taxonomy);

   But here's how I did this:

   <form action="<?php bloginfo('url'); ?>" method="get">
   	<div>
   <?php
   $taxonomies = array('TAXONOMY NAME');
   $args = array('orderby'=>'name','hide_empty'=>true);
   $select = get_terms_dropdown($taxonomies, $args);
   
   $select = preg_replace("#<select([^>]*)>#", "<select$1 onchange='return this.form.submit()'>", $select);
   echo $select;
   ?>
   	<noscript><div><input type="submit" value="Näytä" /></div></noscript>
   	</div></form>

   Combine this with the get_terms_dropdown function described above, with couple of changes:

   function get_terms_dropdown($taxonomies, $args){
   	$myterms = get_terms($taxonomies, $args);
   	$output ="<select name='TAXONOMY SLUG'>";
   	foreach($myterms as $term){
   		$root_url = get_bloginfo('url');
   		$term_taxonomy=$term->taxonomy;
   		$term_slug=$term->slug;
   		$term_name =$term->name;
   		$link = $term_slug;
   		$output .="<option value='".$link."'>".$term_name."</option>";
   	}
   	$output .="</select>";
   return $output;
   }

   This isn't the cleanest solution (and only works with one taxonomy at the time), but it does the trick. It uses a wrong url, but the rewrite should pass the user to the correct page.

   Adding the term count is easy enough - it's in $term->count, so just add that to the $output like this

   $output .="<option value='".$link."'>".$term_name." (".$term->count.") </option>";
