One of the things you will find tricky to implement is the the sorting and filtering of a GridView's column that displays related model data.

There are a few issues with the other solutions I originally used that I found from other wikis. I address the issues I had in this much simpler and shorter way. I am also going to explain what is going into way more detail than others to help people understand what's going on.

This is a simple example in Yii2.0 to understand how you can write a custom component and use it inside your app.(basic template)

This article tries to describe the practical techniques of searching by a HAS_MANY relation using ActiveRecord of Yii 2.0.
