Yes Alex I understand your question. Simply, I saw this possibility, and I think cool, I explain why.
I need very detailed profiles.
To start + - ten obigatory fields with the essential information.
(Submit)
A questionnaire with 10 questions type Textarea
(Submit)
A second questionnaire of 10 questions type Texarea
(Submit)
When we finished completing the second questionnaire, we are very far from the first button "Submit", my goal was to divide into several sections, I fill the first save, the second I save, the 3rd save.
Of course I understood that the 3 buttons saved the whole profile, but I found this possibility to be able to suavergarer in an intermediate way and so not always have to climb to the top interesting.
I thought that the possibility of adding this type of field was made for this scenario, if not why is it present?
