Navigation bar issues, using Bootstrap 4

Hello everyone, I’ve got this responsive navigation bar setup however, the button for the menu once the bar is resized is not working, does anyone have any ideas on how to fix it and what the issue is exactly?

Here’s the pen:

See the Pen bootstrap navbar tests by Victor Varbanov (@TresV) on CodePen.

Check your console! You need to add jQuery in your settings, bootstrap needs it. Also, be sure to add it before the bootstrap’s javascript file.

Edit: Woops. @SkyC beat me to it.


Thanks to both of you!

I had pasted same code in Codeply and it worked like a charm there, apparently they had jQuery and JS enable by default.
