Menu
Any ideas why this Twitter Bootstrap dropdown isn't working?
Javascript in head:
<script src="/assets/js/bootstrap.js" type="text/javascript"></script>
Menu HTML:
<li class="dropdown">
<a data-target="#" data-toggle="dropdown" class="dropdown-toggle" href="#">Dropdown menu here...
<b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li><a href="/app/1">Item A</a></li>
<li><a href="/app/2">Item B</a></li>
<li><a href="/app/3">Item C</a></li>
</ul>
</li>

Solution : The dropdown should be toggled via data attributes or using javascript. In the above program, we have forgotten to add a data attribute so the dropdown is not working. So add data-bs-toggle="dropdown" to toggle the dropdown.
To open the dropdown menu, use a button or a link with a class of . dropdown-toggle and the data-toggle="dropdown" attribute. The . caret class creates a caret arrow icon (), which indicates that the button is a dropdown.
Bootstrap 5 is designed to be used without jQuery, but it's still possible to use our components with jQuery. If Bootstrap detects jQuery in the window object it'll add all of our components in jQuery's plugin system; this means you'll be able to do $('[data-bs-toggle="tooltip"]').
Put the dropdown class on a div that is wrapping the li rather than on the li itself. Like this...
<div class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">Dropdown trigger</a>
<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
...
</ul>
</div>
That example is from the bootstrap site
Your code should look like this...
<!DOCTYPE html >
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>
<script type="text/javascript" src="../plugins/js/bootstrap-dropdown.js"></script>
<link href="../theme/bootstrap.css" rel=stylesheet type="text/css">
</head>
<div class="dropdown">
<ul class="dropdown">
<a data-target="#" data-toggle="dropdown" class="dropdown-toggle" href="#">Dropdown menu here...
<b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li><a href="/app/1">Item A</a></li>
<li><a href="/app/2">Item B</a></li>
<li><a href="/app/3">Item C</a></li>
</ul>
</ul>
</div>
I tried making a nested list, but it didn't work with bootstrap. I think it gets the two dropdowns confused.

Make sure you are using the latest version of JQuery

This is easily solved. The element wrapping your code is a li, but it needs to be a div. This works for me:
<div class="dropdown">
<a data-target="#" data-toggle="dropdown" class="dropdown-toggle" href="#">Dropdown menu here...
<b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li><a href="/app/1">Item A</a></li>
<li><a href="/app/2">Item B</a></li>
<li><a href="/app/3">Item C</a></li>
</ul>
</div>
If you want it to look like a button, just add "btn" to the class list like this:
<a data-target="#" data-toggle="dropdown" class="dropdown-toggle btn" href="#">
My header section looks like this:
<link rel='stylesheet' type='text/css' href='css/bootstrap.min.css'>
<link rel='stylesheet' type='text/css' href='css/bootstrap-responsive.min.css'>
<script src='js/jquery-2.0.0.min.js' type='text/javascript'>
<script src='js/bootstrap.min.js' type='text/javascript'>
You may want to leave out the responsive css if you're not doing anything for mobile devices.
