custom_taxonomy drop down works, but is not heirachical (1 post)

    I have created a drop down of my custom taxonomies using the code below:

    function get_terms_dropdown($taxonomies, $args){
    $myterms = get_terms($taxonomies, $args);
    	$output ="<select name='{TERM}'>";
    	foreach($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."'>".$term_name." (".$term->count.") </option>";
    	}
    	$output .="</select>";
    return $output;
    }

    I then place this in my template:

    <form action="<?php bloginfo('url'); ?>" method="get">
    	<div>
    <?php
    $taxonomies = array('{TERM}');
    $args = array('orderby'=>'name','hierarchical'=>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" /></div></noscript>
    	</div></form>

    It outputs a dropdown populated with the terms but the terms are list totally flat. They are not hierarchical, but 'hierarchical'=>true has been set to true.

    Does anyone have any ideas, why the 'hierarchical'=>true is not getting read?

    Thank you!
