简短版本：

具有支持自定义分类法的自定义帖子类型的自定义菜单。自定义post类型有效，其菜单有效并保持打开状态。自定义分类法可以工作，但侧栏菜单不能保持打开状态。我需要使类别保持子菜单的打开状态，就像它在本机上一样（如果没有放置在另一个菜单中）。

长版本：

我有一个使用add\\u menu\\u页面创建的自定义菜单：

add_menu_page(
  \'Directory\',           // Page Title
  \'Directory\',           // Menu Title
  \'manage_options\',      // Capability
  \'directory\',           // Slug
  null,                  // Rendering Function
  \'div\'                  // Menu Icon (or "div" for CSS)
);

我还创建了一个自定义帖子类型和一个自定义分类法。我想让它们出现在我的自定义菜单中，根据show_in_menu 参数（请参见wiki，无法发布链接），这应该是本机支持的。

然而，它只是does not work correctly. 确实，此选项会将“管理目录”链接粘贴到我的自定义菜单中，但它确实not 将“添加联系人”或“目录类别（自定义分类）”链接移动到菜单中。

以下是一些预览：

默认菜单：http://radleygh.com/images/chrome_2013-114-14-14-53-25.png

如您所见，默认菜单有三个链接。我得走了all of these 到我的自定义菜单（我将在其中添加子菜单）。

我之前学到的一个技巧是，可以为现有页面创建子菜单，它们的行为就像是真正的菜单一样。至少，这适用于大多数情况。它不适用于我的分类法。请参见以下代码：

add_submenu_page( // Manage Directory
  \'directory\',
  \'Manage Directory\',                  // Page Title
  \'Manage Directory\',                          // Menu Title
  \'manage_options\',                    // Capability
  \'edit.php?post_type=directory_post\'  // Slug
);
add_submenu_page( // Add Contact
  \'directory\',
  \'Add Contact\',                            // Page Title
  \'Add Contact\',                            // Menu Title
  \'manage_options\',                         // Capability
  \'post-new.php?post_type=directory_post\'   // Slug
);
add_submenu_page( // Categories
  \'directory\',
  \'Categories\',                             // Page Title
  \'Categories\',                             // Menu Title
  \'manage_options\',                         // Capability
  \'edit-tags.php?taxonomy=directory_category&post_type=directory_post\'  // Slug
);

上面的代码为我提供了所需的链接，每个链接的“slug”足够聪明，可以指向正确的页面。事实上，这些链接似乎是本地链接。但当然，他们不是。

但问题是，出于某种原因，“类别”链接本身并不能保持菜单的打开状态。其他人是这样的。

我认为问题在于分类法不支持“show\\u in\\u menu”参数。尽管正如我上面解释的那样，这个参数是“坏的”，但它至少保持了菜单的打开状态。
