Once you get used to working with Prawn it's very quick and easy. What would you recommend using converting a user customised template (maybe through liquid) to PDF? 

Thanks for this   David Kimura  very helpful!

This is great! I've been looking to create a combo box (that's not just a dropdown select) and this can be modified to do just that!

This is the best, thanks for the effort that went into this one   David Kimura  

I can replace my rather expensive JS calendar plugin with these eventually!

What about refreshing after a controller action? Do we just replace / update the frame?
