二级分类添加文章
1级分类的文章是通过查询下面所有子分类的文章，
但是如果用户在添加文章的时候选择一级分类，前台将不会显示它所添加的文章,因为显示的
是所有子分类文章。
回复讨论(解决方案)
你要问什么呢？
如果是用户，他们如果选择1J分类，此时他们所添加的文章将不能在前台显示.

你在后台把1级类别的选项改成不能选择的就可以了，这样客户就不会选择到1级类别了

你现在是要将用户选择的1级分类下的文章不显示出来，还是显示出来？

搞定了，我后台有1J分类和2J分类都有，我添加一个是否有子类字段，来判断是否可以选择，
不过貌似它不支持IE6，接下来就是调兼容性了,谢了，知道option有是否可以选择这个属性就好办了。
