Bootstrap 5 navbar not collapsing-CodePudding

i have an issue with bootstrap 5 navbar toggle. It's not toggling. Exactly same code with bootstrap 4 works fine.

I've already tried by some examples to remove navbar-toggler class from button and navbar-collapse class from navbar but it didn't work.

Workaround that I've used is to add onclick element to a button which would point to javascript which will add show class to navbar but I need to figure out why the native method doesn't work.

Tried on Firefox running on Fedora linux and Chrome running on Android 11 phone.

Bootstrap 5 example (not working):

CodePudding user response：

Change two things:

data-toggle="collapse" (Bootstrap 4) to data-bs-toggle="collapse" (Bootstrap 5)
data-target="#navbarNavAltMarkup" (Bootstrap 4) to data-bs-target="#navbarNavAltMarkup" (Bootstrap 5)

See the snippet below.
