So the first thing I checked was your website and I noticed you have a whole bunch of errors
Code:

The actual javascript error is this one -
Code:
hybridmenu.js:9 Uncaught ReferenceError: jQuery is not defined
at hybridmenu.js:9
That's happening because jQuery isn't being loaded.
Now check this error -
Code:
Mixed Content: The page at 'https://danskeren.com/menus/hybrid/' was loaded over HTTPS, but requested an insecure script 'http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js'. This request has been blocked; the content must be served over HTTPS.
Your website is forcing HTTPS, but its trying to load resources from a non-secure address (not https).
The browser will not load the resources, so the script breaks.
In chrome if you select the insecure content blocked and click "allow unsafe scripts", the website works fine. You'll need to load the resources over https.
