Question

如何在我创建的插件的选项页面中添加（可拖动）元框？这甚至可能吗？因为如果我查看文档，我会发现我只能将其添加到“帖子”，“页面”，“链接”或“custom_post_type”。

Answer 1

是的，这是可能的。您上一个问题中的代码是正确的，但它错过了一些重要的内容，或者您没有将该代码添加到问题中。

这是demo plugin，可以帮助您实现目标。

此插件演示如何使用WordPress提供的可拖动元文件构建自己的插件页面，需要WordPress 2.7版本，支持WordPress 2.8更改拳击布局引擎

demo插件的基本代码如下。请注意，在完整示例中，侧元框不起作用，也没有为WordPress 2.8编写的两列布局，当前版本几乎为5.0。
