In the form http://katonahchamber.org/membership-form/ where businesses submit their info, some fields are optional. I use content template to display this info here http://katonahchamber.org/business/noka-noka-joes/. How to hide "hours" or "fax" sections if these fields weren't submitted. Here is the example of content template
