Navigation Menu - collapse button

I am having some trouble getting my button showing a drop down menu to work. I would really appreciate some help.
Thank you!

Your CodePen link seems to be broken. Did you solve your problem?

Yep, link broken, so we can`t check it.
Btw. make sure you include jquery and bootstrap libraries in your pen settings.

Sorry.

I didn’t manage to solve it.

It’s just as @kirbyedy said, you need to include jquery and bootstrap in your JavaScript section.

Thanks alot @kirbyedy and @PortableStick, I will add JQuery and bootstrap when I get home.
