Reliez rows et state à SelectBinding. Transmettez la navigation et l’activation ; son intention de sélection typée identifie la destination à ouvrir.
Gauche et Droite demandent l’élément actif précédent ou suivant. Projetez le nouvel état pour surligner l’action active et la rendre visible dans le défilement. Avec SelectBinding, rouvrez le contrôle persistant après un choix validé.
