Why Doesn't My Bootstrap 5 Navbar Dropdown Expand?

Navbar Dropdown Remains Static in Bootstrap 5

Issue:

When creating a responsive menu or dropdown button with Bootstrap 5, navigation icons and dropdown icons appear, but fail to expand when clicked. Despite including the jQuery file, the dropdown menu does not display.

Cause:

In Bootstrap 5, data attributes have been updated to "data-bs-*" instead of "data-target."

Solution:

Replace the following line in your code:

<button></button>

With this updated line:

<button></button>

Additional Considerations:

• Bootstrap 5 has introduced breaking changes, including the replacement of spacing classes like "mr-auto" and "ml-auto" with "ms-auto" and "me-auto."
• The use of "data-bs-*" attributes ensures compatibility with Bootstrap 5's namespace and distinguishes it from third-party JavaScript components.
