Why doesn't my bootstrap data toggle work in navbar?

Question

Below I have code to create a simple consolable navbar with Bootstrap 5 with a logout button, the logout button does collapse into a data toggle but the data toggle doesn't work when you click it any ideas?

@ManasKhandelwal I'm using it in the full version of the site and just left it in, sorry. — qwertyuiop, Mar 26 '21 at 22:44

Try moving your jQuery and bootstrap js script tags to the bottom of the body tag.

Or, try adding this boostrap script CDN: https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js

This has to do nothing with his problem. Also what is the problem in the CDN he is using. – Manas Khandelwal Mar 26 '21 at 22:47
You need JQuery for bootstrap to work btw. I am not sure what the popper version is for. – Matthew Haywood Mar 26 '21 at 22:48
At least do some research before posting. Bootstrap has dropped jquery. – Manas Khandelwal Mar 26 '21 at 22:49
Ok I thought he was using Bootstrap 4. – Matthew Haywood Mar 26 '21 at 22:51
Just thought I would add, actually you don't need any javascript for bootstrap to work no matter the version. Its only if you need the features that are dependent upon javascript. I stopped using anything but the css years ago. The css is convenient for website responsiveness. – Bruce Mar 26 '21 at 23:21

I was using out of date code from the old docs (facepalm)

The code at this link works fine: https://getbootstrap.com/docs/5.0/components/navbar/

New code:

<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">

</head>

<body>
  <nav class="navbar navbar-expand-sm navbar-dark bg-dark">
    <div class="container-fluid">
      <a class="navbar-brand" href="index.php">Document</a>
      <div class="d-flex align-items-center">
        <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
                        <span class="navbar-toggler-icon"></span>
                    </button>
      </div>

      <div class="collapse navbar-collapse" id="navbarSupportedContent">
        <ul class="navbar-nav ms-auto">
          <form name="logout" class="logout" action="PHP/Logout.php" method="get">
            <button type="submit" class="btn btn-danger">Log Out</button>
          </form>
        </ul>
      </div>
    </div>
  </nav>
