Bootstrap Dropdown Functionality Malfunctioning

Here is a simple piece of HTML code that I have created:

<!doctype html>
<html>
    <head>
        <meta charset="utf-8">

All necessary Bootstrap, Fontawesome, and jQuery files have been included in the code. However, there seems to be an issue with the dropdown functionality of the navbar and fixing it at the top while scrolling. If you have any insights or suggestions on how to troubleshoot these problems, please let me know. Your help would be greatly appreciated.

P.S.: Despite multiple attempts, I am unable to resolve these issues. It could be due to work pressure affecting my concentration. Any assistance would be valuable in overcoming these challenges.

Answer №1

It appears that there may be an issue with your bootstrap css being overwritten.

Upon clicking the button, you should see the open class applied to the dropdown.

To resolve this, I included the following CSS code snippet:

.dropdown > .dropdown-menu {
  display: none; //hides .dropdown-menu directly inside .dropdown
}
.dropdown.open > .dropdown-menu {
  display: block; //shows .dropdown-menu directly inside .dropdown if it has class .open
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

<li class="dropdown">
  <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
  <ul class="dropdown-menu">
    <li><a href="#">Action</a>
    </li>
    <li><a href="#">Another action</a>
    </li>
    <li><a href="#">Something else here</a>
    </li>
    <li role="separator" class="divider"></li>
    <li class="dropdown-header">Nav header</li>
    <li><a href="#">Separated link</a>
    </li>
    <li><a href="#">One more separated link</a>
    </li>
  </ul>
</li>

Answer №2

To ensure proper functionality, make sure to load jquery before boostrap.js.

Here is a suggested order:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

Try implementing this sequence and check if it resolves the issue.

Answer №3

My issue stemmed from a discrepancy in bootstrap versions. I found the following in my header file:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

Upon closer inspection, I realized that one version was 3.3.6 while the other was 3.3.7. A simple adjustment of changing 3.3.6 to 3.3.7 resolved the issue and my dropdowns began functioning properly once again.
