Fournissez les OptionRow du niveau racine au niveau courant. Traitez activate(token, generation) pour ouvrir une destination parente.
Le dernier élément est un texte courant, sans action ; les éléments précédents restent des boutons nommés. La barre peut défiler horizontalement lorsque le chemin est long.
