Add custom fields from user

Hi,
I'd like to have to my community the possibility to give to each user to select how many different field for an argument.

For Example:
Have you got children? yes no
(IF YES, or anyway without control question directly)

Name of child _________________________
Age of child _________________________
Phone number of child _________________

+ / -

(when user click on + automatically other x fields, in this case 3, appear for a new child, if user wrong and want to eliminate 1 child's field just click on -)

This cabability, or similar I've seen on SOBI PRO, with difference that any user can manage all records, I'd like to have inside cb couse every user can manage only their own record (and the administrator also can do)

Thank you for this possibility

We've no such feature, but it's planned for CB 2.0. Your only solution for now is to create a bunch of duplicate field sets and use CB Conditional to show/hide them based off a counter dropdown. For example you'd have a dropdown with values None, 1, 2, 3, and 4 then show a set of fields based off the number selected.
