Fournissez rows et state depuis SelectBinding ou un contrôleur de sélection, puis relayez les callbacks de navigation, d’ouverture et d’activation. Placez le libellé sélectionné dans placeholder, qui fournit le texte du déclencheur.
L’activation transmet token et génération ; le contrôleur confirme la sélection et gère les options désactivées. SelectionAvailability.unavailable signale un choix devenu indisponible, et tab-navigation permet à l’hôte d’avancer le focus après fermeture.
