When clicked submenu on mobile are not clickable, do not navigate to the URL

My Foundation for sites menu and submenu work fine on desktop, but the submenu links are not clickable on iOS and Android. I would really appreciate anybody’s help.
I think there might be an issue with JS or the paths or the JS file itself.
Could anyone give any hints please?

Here is the link to codepen with some of the code, mainly navbar.html
Thank you so much!

In general you use an old version of Foundation (6.2.3), the latest is 6.6.3.

Please test if it is fixed there.

Thank you so much for replying swiftly!

Sorry, just to clarify, do you mean I should update it to the latest version 6.6.3 and try there, right?

I tried updating it, but it does not get updated in bower_components > bower.json it points to 6.2.4, but in package.json the dependency is 6.6.3.
Sorry, I am still learning, so don’t fully understand, why it would not update.

Thanks again!

I’m not sure if 6.6.3 is available on bower. Bower itself has reached its end of life.
You can try to set it to 6.6.3 in bower.json and run bower install again.

Only npm (and yarn) uses package.json. Or where is the package.json that you mean?

Correct, we may have fixed this in newer releases and there are also the options and attributes to configure a component. The docs are for the latest version.

Thanks a lot! I will try again with the suggestions.
