我有一个称为“自行车类别”的自定义分类法、一个称为“品牌”的自定义术语和一个称为“自行车”的自定义帖子类型

我想列出每个自行车类别，然后在下面列出所有有自行车的品牌。

我已经完成了一半，但似乎资源非常紧张/冗长，我肯定我走错了方向。有人能提出更好的方法吗？

<ul>
<?php
// set up taxonomies

    \'order\'                    => \'ASC\',

    \'hierarchical\'             => 1,
    \'taxonomy\'                 => $tax_one ));

    foreach ( $categories as $category ) : // list all categories

    if($category->slug == $wp_query->query_vars[\'bike-category\']) { $selected = \' class="selected"\'; } else { $selected = \'\'; }

            $terms = get_terms( $tax_two, array( \'hide_empty\' => 0 ) );

            foreach ( $terms as $term ) :  // list all brands in each category
