Fournissez des ChoiceRow, une generation et active-token, puis traitez navigate et activate(token, generation). Choisissez ChoiceDirection.horizontal ou .vertical et la politique ChoiceFlow.
La sélection vient de ChoiceRow.selected, indépendamment du token actif. Le contrôleur applique l’exclusivité et les règles de navigation, tandis que les lignes conservent leurs identités. Avec SelectBinding, rouvrez le contrôle persistant après un choix validé.
