If you create custom fields these can be restricted to certain categories e.g. golf events could have a field 'maximum handicap'. Then in your event detail layout this field would only appear for this sort of event. Its possible to put conditional formatting and labels for these fields so that the label/formatting only appears when the field has a value.
This then allows you to construct different outputs for different categories.
I am planning to allow you to create completely different layouts for different categories but this is a few weeks away.
