The Bootstrap dropdown menu and additional links are experiencing functionality issues

I'm still learning HTML/CSS and decided to implement a navbar menu from Bootstrap documentation. However, I encountered an issue where the Dropdown menu and other links are not functioning properly. Here is the code for the navbar:

Answer №1

Eliminate the -bs from the button and anchor attributes data-bs-toggle and data-bs-target.

data-bs is specifically for Bootstrap-5 and not Bootstrap-4. It was introduced to differentiate between actual Bootstrap attributes and regular ones. However, it does not work in Bootstrap-4 as it was only implemented in version 5.

Answer №2

After testing your code with the basic template provided on the official bootstrap website here, I found that integrating your menu code worked seamlessly without any issues. However, upon further experimentation by merging your imports with those from the bootstrap website, I discovered an inconsistency in the import structure from the bootstrap library you used.

The correct import from Bootstrap should look like this:

<script src="https://cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="4b2924243f383f392a3b0b7e657a6578">[email protected]</a>/dist/js/bootstrap.min.js" integrity="sha384-QJHtvGhmr9XOIpI6YVutG+2QOK9T+ZnN4kzFN1RtK3zEFEIsxhlmWl5/YESvpZ13" crossorigin="anonymous"></script>

Your current import structure looks like this:

<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js" integrity="sha384-wfSDF2E50Y2D1uUdj0O3uMBJnjuUD4Ih7YwaYd1iqfktj0Uod8GCExl3Og8ifwB6" crossorigin="anonymous"></script>

I also noticed that you are separately calling both the Bootstrap and Popper libraries. You can simplify this by using a Bootstrap import that includes Popper as well:

<script src="https://cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bfddd0d0cbcccbcddecfff8a918e918c">[email protected]</a>/dist/js/bootstrap.bundle.min.js" integrity="sha384-ka7Sk0Gln4gmtz2MlQnikT1wXgYsOg+OMhuP+IlRH9sENBO0LRn5q+8nbTov4+1p" crossorigin="anonymous"></script>

Here is a functional example based on the adjustments made:

<html lang="en">

    <meta name="viewport" content="width=device-width, initial-scale=1">
