Wordpress在具有很好的菜单用户体验，如果需要在drupal中实现这样的效果，可以参考以下代码：

<?php
$vid = 4;  // Set the vid to the vocabulary id of the vocabulary you wish to list the terms from
$items = array();
$terms = taxonomy_get_tree($vid);
foreach ( $terms as $term ) {
    $count = "(".db_result(db_query("SELECT COUNT(nid) FROM {term_node} WHERE tid = %d", $term->tid)).")";
    $items[] = l($term->name, "taxonomy/term/$term->tid") . " $count";
}
if ( count($items) ) {  print theme('item_list', $items);}
?>

使用taxonomy_get_tree函数实现菜单列表

foreach ( $terms as $term )
{
  $count = "(".db_result(db_query("SELECT COUNT(nid) FROM {term_node} WHERE tid = %d", $term->tid)).")";
  $termdepth = "";
  for ($i=0;$i<$term->depth;$i++)
  {
    $termdepth = $termdepth . "-- ";
  }
  $items[] = $termdepth . l($term->name, "taxonomy/term/$term->tid") . " $count";
}
if ( count($items) ) {  print theme('item_list', $items);}
?>
