搜索节点不会自动展开文件夹或显示子计数器

Question

我已从此链接复制了fancytree过滤器功能的一些代码：http://wwwendt.de/tech/fancytree/demo/sample-ext-filter.html#

我将过滤器功能注入到我构建的树中，但是当我过滤树的项目时，文件夹不会自动展开，并且子计数器不会出现。

我安装的内容：

jquery.fancytree-全DEPS

jquery.fanctree.filter

的jquery-2.2.0

的jquery-UI-1.11.1

我尝试安装我在上面指定的链接的源代码中指定的版本，但这没有帮助。有什么东西看起来不合适吗？我将过滤器属性放在正确的位置，包括过滤器扩展，并包括用于从用户收集数据的加密方法。

我曾试图用这棵树做过的其他事情，但这似乎让我感到沮丧。任何帮助都会很棒！
