2 Layout In One Application

Is it possible to have 2 different layout for a single application?

If yes, How…

It will be used for login page and the admin panel

I can put both in single layout but i don know how to put it separate.

Can anyone give some suggestion ?

Try this cookbook. http://www.yiiframework.com/doc/cookbook/28/

I have successfully implemented it. It is very very flexible. I personally use 4 different layouts.
