As recommended by you guys we have now added the Custom comment option in the Astroid, wherein you can chose a your type for the comments under blogs & articles apart from the different types available.
In this you can create your own comments php file and display it on frontend. The steps to create that file is as follows:
- Create a default_comments.php file on the following path: JOOMLA_ROOT/templates/YOUR_TEMPLATE/html/frontend/blog/modules
- After creating the file just choose comments as Custom. And it’s done!
