Loop

Le composant Loop (parfois appelé BlockForLoop) permet de créer une boucle permettant de poser une série de questions plusieurs fois (exemple: demander des informations sur plusieurs personnes).

paginatedLoop, indique si la boucle doit être paginée ou non (defaut: false)
components, tableau contenant les composants enfant à cette boucle

Boucle non paginée

Une boucle non paginée présentera l'ensemble des champs les uns à la suite des autres.

lines, permet le contrôle sur le nombre de lignes (ajouter / supprimer)
- min, nombre minimal de lignes
- max, nombre maximal de lignes

Boucle paginée

Une boucle paginée déclenchera un système de sous-navigation. Lorsque l'utilisateur arrive sur la page d'une boucle il sera automatiquement redirigé sur la première sous page.

iterations, expression VTL permettant de calculer le nombre d'itérations à effectuer
maxPage, numéro de la dernière sous page

info

Les composants dans le tableau components devront avoir un numéro de page préfixé par la page de cette boucle, ex: 3.1)
