显然，没有办法从必须使用列表中删除一个插件。。。

但后来，发现了一个性能更好的过滤器：
show_advanced_plugins 将完全隐藏必须使用的插件。

毕竟，如果你想隐藏这种性质的东西，那么就把它全部隐藏起来。。。

在教室里WP_Plugins_List_Table 并接受两个参数：布尔值和插件类型(mustuse 和dropins).

检查this article 供MU和specially 访问。但是，为了wiki的缘故，我将在这个答案的末尾发布DI表。

<小时>Update:
-mu-plugin 更新为多个用户和多个隐藏插件，现在是字符串，它是数组

为了测试这个过程，我们需要一个插件。创建名为db.php 在root 并复制以下内容：

<?php
/*
    Plugin Name: Just for testing Drop-ins

<?php
/*
