织梦的联动信息类型只能增加一级和3J选择的解决办法

天外飘仙

今天在做一个织梦企业网站的时候，需要用到分类信息，织梦模板是用的DEDECMS V5.7版本的，在修改联动类别里面的信息类型的时候发现只能增加一级选择和3J选择，就是不能增加二级选择，怎么办呢？

去织梦官方找了下解决办法没得，看来只能自己研究了。

后来使用DEDECMSV5.6版本的进行测试，发现5.6的是可以使用的，那就可以找到解决的办法了。

首先我们找到我们的模板源码下面的 dede/stepselect_main.php 这个文件，

将这段代码

然后保存，在系统后台更新系统缓存就可以了的。现在在后台的联动类别管理里面就可以增加二级选择了。
