in Fullcalendar is there a way to fix the header to not be scrollable

I seem to re开发者_开发问答call that there was an option to set the fullcalendar header to always remain visible when you scroll the rest of the calendar, but I can't seem to find the reference any more. Was it my imagination or was this feature available in an earlier release of fc?

sorry, I think you'll have to do it manually.
