I ask about codeigniter version or any version compatable with it
Thank you for your interest in Metronic.
Metronic at the moment does not have a Codeigniter starter kit. We have Laravel and Symfony Starter kits from PHP frameworks.
However, you can use Metronic's HTML version with any server-side language and framework including Codeigniter as well since Metronic provides HTML5 templates that are easy to integrate with the backend code.
For more info please check Quick Setup guide and First App video tutorials.
