change directory list checkboxes into a dropdown

Anyone could tell me how to change the directory list checkboxes into dropdown select box.
I believe this is the hook inserted in the signup page.
[code]
public static function signup_blogform () {
print '<div id="multisite-directory-signup-categories">';
esc_html_e('Site Categories', 'multisite-directory');
print '

'.self::get_terms_checklist_html().'

';
print '</div><!-- #multisite-directory-signup-categories -->';
}
[/code]
