Use the following function to make check-boxes for taxonomies:
function get_terms_chekboxes($taxonomies, $args) {
$terms = get_terms($taxonomies, $args);
foreach($terms as $term){
$output .= '<label for="'.$term->slug.'"><input type="checkbox" id="'.$term->slug.'" name="'.$term->taxonomy.'" value="'.$term->slug.'"> '.$term->name.'</label>';
}
return $output;
}
echo get_terms_chekboxes('country', $args = array('hide_empty'=>true));
Hope this will help you!
