Hi Toby,

I'm afraid, but there's currently no way of implementing your needs within 
formfu.

One possibility to achieve your goal might be in useing css to reposition the 
fieldelements the way you need it.

Nontheless I though myself of splitting forms and nested_elements into 
different fieldsets and to extend formfu for that purpose, but that is not on 
my schedule yet. 


Greets,
