Why isn't my Bootstrap 5 navbar dropdown working even with jQuery?

Bootstrap 5 Navbar Dropdown Issue

When attempting to implement a responsive navigation menu using Bootstrap 5, users may encounter an issue where the dropdown button or menu item does not function as intended. This issue can arise even when jQuery is included in the project.

Cause

In Bootstrap 5, the data-* attributes for JavaScript plugins have changed. Previously, data-toggle and data-target were used, but in Bootstrap 5, they have been replaced with data-bs-toggle and data-bs-target respectively.

Solution

To resolve the issue, replace the old data- attributes with the new data-bs- attributes:

<button>

Additional Considerations

Besides the change in data-* attributes, Bootstrap 5 also introduces other changes. For example, the ml-auto and mr-auto classes have been replaced with ms-auto and me-auto.

Demo

This code snippet demonstrates the functioning dropdown button:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Bootstrap</title>
    <link
        href="https://cdn.jsdelivr.net/npm/[email&#160;protected]/dist/css/bootstrap.min.css"
        rel="stylesheet"
        integrity="sha384-giJF6kkoqNQ00vy+HMDP7azOuL0xtbfIcaT9wjKHr8RbDVddVHyTfAAsrekwKmP1"
        crossorigin="anonymous"
    />
</head>
<body>
    <nav>
