Création de formulaires

Bonjour
Je voudrais créer un formulaire spécial
J'ai 2 types de compte sur mon site.
je voudrais que les gens puissent créer leur compte normalement en choisissant le type de compte et ensuite leur proposer un autre formulaire en fonction du type de compte choisi.

Hello I would like to create a special form I have 2 types of account on my site. I would like people to create their account normally by choosing the type of account and then offer them another form depending on the type of account chosen.

Please note support here is provided in English only. If you don't know English be sure to run your post through Google Translate at the least. Future non-English posts will simply be ignored, sorry.

Regarding your needs the best way to do that is to have a field for the user to select their profile type (e.g. select, radio, etc..) then use CB Conditional to show/hide other fields based of that profile type selection.

Oh sorry my english a little bad.
I use CB conditionnals. What i want to do is to create a formulaire where the first step is the namae the mail & password.
And after i force them to complete their profile.

There's no way to force them to complete their profile after registration. You can of course have fields marked as required and they won't be able to save their profile without filling in those required fields, but it's not going to force them to stay there to complete those fields. If you're meaning you just want registration to be broke up into steps you can enable Step by Step registration within CB > Configuration > Registration.
