Is it possible to make subposts under every posts in a single thread? 

Means I want to show members response to someone's post in a thread which remain hidden under posts or show like spoiler but can be accessible to members. It should be possible in every posts  of a thread . 
Is it possible. 
Thank you 

Anyone having an idea related to this???

please help.

Lol, post commenting!

Maybe a plugin could do it. Using threaded mode may also work, but I don't see the purpose of this.
