我有一个小问题，我找不到答案。。。我已经创建了自定义帖子类型和自定义分类法，但我的自定义分类法显示为自定义pos类型下的子菜单，下面是 example what I need 我该怎么做？？？以下是我的分类法和帖子类型的注册方式：

<?php

function inkodus_register_taxonomy() {
    // set up labels
    $labels = array(
        \'name\'              => \'Manufactures\',
        \'singular_name\'     => \'Manufacture\',
        \'search_items\'      => \'Search Manufactures\',
        \'all_items\'         => \'All Manufactures\',
        \'edit_item\'         => \'Edit Manufacture\',
        \'update_item\'       => \'Update Manufacture\',
        \'add_new_item\'      => \'Add New Manufactures\',
        \'new_item_name\'     => \'New Manufactures\',
        \'menu_name\'         => \'Manufactures\'
    );
    // register taxonomy
    register_taxonomy( \'manufactures\', \'manufactures\', array(
        \'hierarchical\'      => true,
        \'labels\'            => $labels,
        \'query_var\'         => true,
        \'show_admin_column\' => false,
        \'show_ui\'           => true
    ) );
}
add_action( \'init\', __NAMESPACE__ . \'\\\\inkodus_register_taxonomy\' );

function inkodus_create_post_type() {

    //setting up labels
    $labels = array(
        \'name\'                  => \'Furnitures-systems list\',
        \'singular_name\'         => \'Furniture-system\',
        \'add_new\'               => \'Add New System\',

        \'parent_item_colon\'     => \'\',
        \'menu_name\'             => \'Furniture Systems
        \',
    );

    //registering post type
    register_post_type( \'furnituresystem\', array(
            \'labels\'                => $labels,
            \'has_archive\'           => true,
            \'public\'                => true,

            \'taxonomies\'            => array(\'manufactures\' ),
            \'exclude_from_search\'   => false,
            \'capability_type\'       => \'post\',
            \'rewrite\'               => array( \'slug\' => \'furnituresystem\' ),
            \'register_meta_box_cb\'  => \'add_attributes_metabox\'
        )
    );
}
add_action( \'init\', __NAMESPACE__ . \'\\\\inkodus_create_post_type\' );
