Grails JQGrid 4.0
===

This problem also concerns my [question][1] regarding the multiple grouping inside the JQGrid using the `<jqgrid:grid>` tag. But as I later found out [here][2] in the changelog of JQGrid, there might be issues with the grouping feature of JQGrid version 3.8.0. I've tried using the scripting format of JQGrid presented here 

So in theory, I would download JQGrid 4.0 and use it in the concerned project.
The question is how can I use the downloaded JQGrid 4.0 files to my project.
