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。

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。
