Joomla 替代布局适用于一篇文章，但不适用于另一篇文章

我正在使用Joomla3.x并创建一个文章覆盖。它适用于某些文章。但当我应用到另一篇文章时，在单个文章菜单项中，它不起作用

更新

这是我的整个覆盖文件：

解决了

我创建了一个自定义菜单项类型

代码？链接例子？您尝试了什么？我在html模板文件夹中保存了default.php（com_content/views/article/tmpl）的一个副本，并使用正常过程将替代布局应用于某些文章。但它只适用于特定类别内的文章。我试图在另一个类别的文章中应用它，但什么也没有发生。请显示您正在使用的代码。有两种替代方法，一种是带有xml文件的，另一种是不带xml文件的。不带的种类适用于实际项目，但它可以被菜单覆盖，因为菜单比项目更具体。带有xml文件的类型只能通过菜单使用。
