XF 1.5 Hide Section Header of a Node

[Nirjonadda]

I have disabled posting (Allow new messages to be posted in this forum) the main node for utilizing the child nodes to categorize the threads. How to remove the section header of the a particular parent node. I also want to know how to hide (You have insufficient privileges to post here.) message of a particular parent node.

This shows because the node is a forum and is thus designed to contain threads. If you don't want that section or the message about not posting there, you should create a category node.
