Hi guys, I’m answering this old post since actually I have the same problem (freezing columns) and had a look at Kartik’s DynaGrid as Jacob suggested.
Unfortunately I didn’t find any reference in the documentation.
Was anybody able to do that?
I’m also open to switching to other extensions, if well integrated into Yii framework.
Datatables would be a great solution but it seems it’s not very well integrated with the ecosystem.
