I want to configure http://demos.krajee.com/grid module in my Yii2 project. The steps given in their documentation asking me to install this extension through composer. But I want to configure it manually without using composer.
I've followed steps given in this document to configure extension without using composer and it worked for me
Same way are there any steps to configure module manually without using any composer.
