CGridView filter positioning

I’d like to reposition my gridview filters. I know this can be achieved with filterPosition property but I actually want to move them outside of the widget entirely. Is this possible?

Would this need to be done by extending the controller, if so any pointers would be most welcome…

Maybe you could disable filter on gridview and use the some thing like the "Advanced Search" generated by CRUD

Spot on that worked perfectly. Thanks for your help.
