从自定义分类生成wordpress菜单

我创建了一个具有一些自定义分类法的自定义帖子类型（产品）。其中之一是"类别"。我希望使用自定义分类法"category"自动生成"Products"下的菜单，这样他们就可以在菜单上单击PRODUCTS -> <category>，它会将他们带到该类别的特定产品列表中（我已经有一个显示单个产品的页面，还有一个列出所有产品的页面）。请注意，一些category分类法会有子分类法，我也想在菜单中显示这一点。

我对wordpress有点陌生，我知道如何创建菜单的唯一方法是通过wp管理员，但我不想为每个类别和子类别创建页面/菜单。

我所说的可能吗？非常感谢。

自定义邮件类型在这里：

add_action( 'init', 'create_product_post_type' );
function create_product_post_type() 
{
    $labels = array(
        'name' => _x('Products', 'post type general name'),
        'singular_name' => _x('Product', 'post type singular name'),
        'add_new' => _x('Add New', 'product'),
        'add_new_item' => __('Add New Product'),
        'edit_item' => __('Edit Product'),
        'new_item' => __('New Product'),
        'view_item' => __('View Product'),
        'search_item' => __('Search Products'),
        'not_found' => __('No products found'),
        'not_found_in_trash' => __('No products found in Trash'),
        'parent_item_colon' => '',
        'menu_name' => 'Products'           
        );
    $args = array(
        'label' => __('Products'),
        'labels' => $labels,
        'public' => true,
        'can_export' => true,
        'show_ui' => true,
        '_builtin' => false,
        'capability_type' => 'post',
        'menu_icon' => get_bloginfo('template_url').'/functions/images/product.png',
        'hierarchical' => false,
        'rewrite' => array( "slug" => "product" ),
        'supports' => array('title'), //MAYBE add thumbnail later!
        'show_in_nav_menus' => true
        );
        register_post_type( 'product', $args);  
}

下面是分类法：

function create_productcategory_taxonomy() {
    $labels = array(
        'name' => _x( 'Categories', 'taxonomy general name' ),
        'singular_name' =>_x( 'Category', 'taxonomy singular name' ),
        'search_items' =>  __( 'Search Categories' ),
        'popular_items' => __( 'Popular Categories' ),
        'all_items' => __( 'All Categories' ),
        'parent_item' => null,
        'parent_item_colon' => null,
        'edit_item' => __( 'Edit Product Category' ),
        'update_item' => __( 'Update Product Category' ),
        'add_new_item' => __( 'Add New Product Category' ),
        'new_item_name' => __( 'New Product Category' ),
        'separate_items_with_commas' => __( 'Separate categories with commas' ),
        'add_or_remove_items' => __( 'Add or remove product categories' ),
        'choose_from_most_used' => __( 'Choose from the most used categories' )
        );
    register_taxonomy('productcategory', 'product', array (
        'label' => __('Product Category'),
        'labels' => $labels,
        'hierarchical' => true,
        'show_ui' => true,
        'query_var' => true,
        'rewrite' => array( 'slug' => 'product-category'),
        )); 
}
