Fournissez les ChoiceRow, generation et active-token du contrôleur. Relayez navigate et activate et choisissez ChoiceFlow.left-to-right ou .right-to-left pour la navigation.

Les segments sélectionnés utilisent l’intention principale et exposent un rôle radio. Le focus commun et la sélection contrôlée restent distincts ; les libellés peuvent revenir à la ligne. Avec SelectBinding, rouvrez le contrôle persistant après un choix validé.
