I would like to create a form with CCK.
The user should be able to create unlimited number of "people" :
M - Smith - John Mrs - Dave - Lily M - John - Doe ...
So I need a Select (with gender) - textfield (last name) - textfield (first name).
I can not create each field to unlimited it would not be linked. I have tried field_group, but it does not give me the ability to put multiple value.
What would be the best way to do that ? I thought about create my own field with those 3 inputs. but it seems way to complicated for the simple thing I need to do. further more I cannot find any good tutorial.
EDIT : I'm using Drupal 7
