You probably create the form from some object (= your model)
Let's say you have a model "Passbook" with a m:m relation to "fields".
One field could have the properties "value", "label", "changeMessage" 
and "keyValue" and the latter could be empty for basic fields and 
specified for special fields (you could also use two different classes 
and "single table inheritance").

Then, in your fluid template, you could simly write:

<f:if condition="{field.label}">
   {field.label}
</f:if>

Alternatively you could add a getter to the Field model 
"hasExtendedFields()" that returns TRUE or FALSE.
