I am using your plugin for a few days now with utmost gladness and I specially enjoy its flexibility.
Right now, I have defined a few custom attributes but I don't want them to appear in the post if they are not defined.
What's the quickest way to get this done?

For posts under the category festivals for example, I don't want the genre field to show if it is undefined under attributes. This is however 'ok' for concerts.
