How to let user decide how comments be sorted The scenario is, in a project comments has a vote up/down field so users can rate a comment. What I'm looking for now is a solution so user can decide if comments should be sorted by date created (newest first) or by its rate (top rated first).
Should I use a views for that? if so how can I hide main comment section?
It seems that the most obvious way to manage your user's behavior on comments would be to use Views. 

And if you want to hide the main comment section, you can do so in your content type's parameters (check the comment section of you content type). You'll see stuff like hide and close.

Hope that gives you a start point.
