How Can I Make JFCB FB commenting box to appear below a module

There isn't a way to move the Comment box below another section of K2. The Content plugin can only see an alter the article's contents. That's how K2 works. So, we can only add the comment box to the end of that article.

What you can do is create a JFBCComments module instance and put it in a module position under the Related News area. That should help get you what you're looking for, but it depends on the module positions available in your template.

I hope that helps,

In the JFBConnect -> Social configuration area, you can configure where and how the comments and social buttons are automatically added to your content. In there is where you'd disable that functionality.
