Bootstrap 5 navbar not collapsing

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):

<!doctype html>
<html lang="sr">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, user-scalable=false, initial-scale=1">
    <link rel="icon" href="{{ url_for('static', path='/images/favicon.png') }}" sizes="32x32" />

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.

<!doctype html>
<html lang="sr">

<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, user-scalable=false, initial-scale=1">
  <link rel="icon" href="{{ url_for('static', path='/images/favicon.png') }}" sizes="32x32" />

            </button>
      <div class="navbar-collapse collapse" id="navbarNavAltMarkup">
