Bonjour,
Merci pour ce PR par contre je pense ca peut poser soucis si le template est appellé plusieurs fois sur la meme page. Ca risque de faire plusieurs fois la fonction addScenariosFilter ou l'écraser. Vu que la fonction n'est appelé qu'a un seul endroit il y a peut etre moyen de ne pas faire de fonction justement.

Je pense que celui la peut etre fermé vu qu'on a passé l'autre non ?
