我创建了一个用于product woocommerce的post类型。

由于某些原因，当您转到编辑屏幕时，它显示为禁用。

这是我用来生成分类法的代码：

add_action( \'init\', \'mk_restrict_product_by_tag\', 0 );
function mk_restrict_product_by_tag() {

$labels = array(
    \'name\'                       => \'Restricted Tags\',
    \'singular_name\'              => \'Restricted Tag\',
    \'menu_name\'                  => \'Restricted Tags\',
    \'all_items\'                  => \'All Restricted Tags\',
    \'parent_item\'                => \'Parent Restricted Tag\',
    \'parent_item_colon\'          => \'Parent Restricted Tag:\',
    \'new_item_name\'              => \'New Restricted Tag\',
    \'add_new_item\'               => \'Add New Restricted Tag\',
    \'edit_item\'                  => \'Edit Restricted Tag\',
    \'update_item\'                => \'Update Restricted Tag\',
    \'view_item\'                  => \'View Restricted Tag\',
    \'separate_items_with_commas\' => \'Separate Restricted Tags with commas\',
    \'add_or_remove_items\'        => \'Add or remove Restricted Tags\',
    \'choose_from_most_used\'      => \'Choose from the most used\',
    \'popular_items\'              => \'Popular Restricted Tags\',
    \'search_items\'               => \'Search Restricted Tags\',
    \'not_found\'                  => \'Not Found\',
    \'no_terms\'                   => \'No Restricted Tags\',
    \'items_list\'                 => \'Restricted Tags list\',
    \'items_list_navigation\'      => \'Restricted Tags list navigation\'
);
$args = array(
    \'labels\'                     => $labels,
    \'hierarchical\'               => false,
    \'public\'                     => false,
    \'show_ui\'                    => true,
    \'show_admin_column\'          => true,
    \'show_in_nav_menus\'          => false,
    \'show_tagcloud\'              => false,
    \'rewrite\'                    => false,
    \'show_in_quick_edit\'         => true,
    \'capabilities\' =>
            array (
              \'manage_terms\' => \'manage_categories\',
              \'edit_terms\' => \'manage_categories\',
              \'delete_terms\' => \'manage_categories\',
              \'assign_terms\' => \'edit_posts\',
            )
);
register_taxonomy( \'mk_restricted_tag\', array(\'user\',\'product\'), $args );
}

WordPress正在生成的HTML：

    <div id="tagsdiv-mk_restricted_tag" class="postbox " >
    <button type="button" class="handlediv button-link" aria-expanded="true"><span class="screen-reader-text">Toggle panel: Restricted Tags</span><span class="toggle-indicator" aria-hidden="true"></span></button>
    <h2 class=\'hndle\'><span>Restricted Tags</span></h2>
    <div class="inside">
        <div class="tagsdiv" id="mk_restricted_tag">
            <div class="jaxtag">
                <div class="nojs-tags hide-if-js">
                    <label for="tax-input-mk_restricted_tag">Add or remove Restricted Tags</label>
                    <p><textarea name="tax_input[mk_restricted_tag]" rows="3" cols="20" class="the-tags" id="tax-input-mk_restricted_tag"  disabled=\'disabled\' aria-describedby="new-tag-mk_restricted_tag-desc"></textarea></p>
                </div>
            </div>
            <div class="tagchecklist"></div>
        </div>
    </div>
</div>

如您所见，文本区域已禁用。如果我将分类法转换为层次结构，则复选框将被禁用（并且我确实可以看到术语）。

知道为什么会这样吗？
