In this page https://diversitequebecofficiel.com/evenement/evenement/1-integration-socioprofessionnelle-et-diversite dropdown OPTIONS DE L'ÉVÉNEMENT doesn't work.

But the dropdown in Cassiopeia template see: https://diversitequebecofficiel.com/evenement/evenement/1-integration-socioprofessionnelle-et-diversite?template=cassiopeia
How can I resolve that thanks ?
