Accordion don't work

Hello everyone,

I have a website for my student company which uses accordions.

But they don’t work, in fact they won’t fold out.
Is this an issue or is this a programming problem, I can’t figure it out…

Thanks in advance!

Kind regards,

This website


Can you please post the code what yo have used for that, so we can check if that’s correct and also, please try to deactivate all your plugins, maybe it’s just a javascript issue.

Best Regards,
