Form Builder Collapse

Is it possible to generate forms with the default classes to do collapse-able sections like used on the browse page or do i have to write my own code for this?

not sure what you are asking.

ok, try to explain ...

1) I create a form with the BxDolForms class
2) say that I have 20 fields in the whole form
3) I want to group every 5 fields to a collapse-able group
4) a collapse-able group like you can see it on the member browse page for "sex, age, country"
5) all groups should be posted as one form

Is this possible with the default dolphin forms class or do i have to write it on my own?

Oh, and what will happen if i create several forms on one page with the same "submit_name"
param but only generate the Submit button for the last form. Will this work?

Thanks!
