My Bootstrap Navbar Hamburger is not working!

Hello everyone :)) …
My navbar hamburger is not working in mobile View… don’t know why?
can anyone please identify me … its simply working in html/Css but not working in my react project …
git repo is in below:

Does it though? I see non of the expected class or data attributes. Can you show me the plain HTML version with Bootstrap working?

Again mixing V4 and V5 of Bootstrap is just a bad idea and in V4 you need jQuery as well for some of the JS features to work.

Can I ask what the reason is for converting this into React? Is it just for practice or what? I would certainly not suggest doing so for a real site unless the developers working on it has a firm grasp on React. Otherwise, it will just become a mess.

I would suggest you look at React Bootstrap as well.
