Codepen.io dropdown function not enabled

I am busy with the completion of the Responsive Web Design projects but, I do not seem to have the drop down menu available?

Has anyone experienced this? If so, possible solution?

have you forked the given template?

can you share the link to your pen?

note it needs cookies enabled, and it can be hidden by some extensions

It needing cookies would make sense. I will disable the ad-blocker and try again.

Thank you
