My dropdown menu in Bootstrap doesnt appear to be working - can anyone alert me to the problem? Right now it displays the dropdown, but clicking it does nothing. Thanks!

$(document).ready( function() {
$('.dropdown-toggle').dropdown();
});

<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container" style="width: auto;">
<a class="brand" style="text-indent: 3em" href="#">
Title
</a>
<ul class="nav">
<li>Profile</li>
<li class="active">Statistics</li>
<li>Reader</li>
<li class="dropdown" id="menu1">
<a class="dropdown-toggle" data-toggle="dropdown" href="#menu1">
Options
<b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li class="divider"></li>
<li>Separated link</li>
</ul>
</li>
</ul>

Answer 1

Check if you're referencing jquery.js BEFORE bootstrap.js and bootstrap.js is loaded only once. That fixed the same error for me:
<script type="text/javascript" src="js/jquery-1.8.0.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>

Answer 2

This is a Rails specific answer, but I had this same problem with Bootstrap dropdown menus in my Rails app. What fixed it was adding this to app/assets/javascripts/application.js:
//= require bootstrap
Hope that helps someone.

Answer 3

putting
<script src="js/bootstrap.min.js"></script>
file at the last after the
<script src="jq/jquery-2.1.1.min.js"></script> solved this problem for me .
this is how i use write it now and no problem
<script src="jq/jquery-2.1.1.min.js"></script>
<script src="js/bootstrap.min.js"></script>

Answer 4

Double importing jquery can cause Error
<script src="static/public/js/jquery/jquery.min.js"></script>
OR
<script src="https://code.jquery.com/jquery-3.4.1.slim.min.js" integrity="" crossorigin="anonymous"></script>

Answer 5

I had to download the source files instead of just the compressed files that it says to use for quick start on the bootstrap website

Answer 6

I had a similar problem. The version of bootstrap.js that visual studio seems to be hosed. I just pointed to this URL instead:
<link id="active_style" rel="stylesheet" href="//netdna.bootstrapcdn.com/bootswatch/3.1.1/cosmo/bootstrap.min.css">
For completeness, here's the HTML and javascript
<ul class="nav navbar-nav navbar-right">
<li id="theme_selector" class="dropdown">
Theme <b class="caret"></b>
<ul id="theme" class="dropdown-menu" role="menu">
<li>Amelia</li>
<li>Cerulean</li>
<li>Cyborg</li>
<li>Cosmo</li>
<li>Darkly</li>
<li>Flatly</li>
<li>Lumen</li>
<li>Simplex</li>
<li>Slate</li>
<li>Spacelab</li>
<li>Superhero</li>
<li>United</li>
<li>Yeti</li>
</ul>
</li>
</ul>
Javascript
$('#theme li').click(function () {
//alert('item: ' + $(this).text());
switch_style($(this).text());
});
Hope it helps someone

Answer 7

I've scratched my head for the last few hours and only figured it is due to difference between bs4 and bs5, namely you should replace data-toggle="dropdown" in bs4 with data-bs-toggle="dropdown" in bs5 and vice versa, hope that helps

Answer 8

If I am getting you correctly, when you say that clicking does nothing, do you mean that it does not point to your URL?
In the anchor tag <a href>it looks like you did not pass your file path to the href attribute. So, replace the # with your actual path for the file that you want to link.
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li class="divider"></li>
<li>Separated link</li>
I hope this helps with your issue.

Answer 9

you are missing the "btn btn-navbar" section. For example:
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
Take a look to navbar documentation in:
Twitter Bootstrap

Answer 10

If you are using electron or other chromium frame, you have to include jquery within window explicitly by:
<script language="javascript" type="text/javascript" src="local_path/jquery.js" onload="window.$ = window.jQuery = module.exports;"></script>

Answer 11

When i checked i saw display: none; value is in the .dropdown-menu bootstrap css class. Hence i removed it.

Answer 12

put following code in your page
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequest);
function EndRequest(sender, args) {
if (args.get_error() == undefined) {
$('.dropdown-toggle').dropdown();
}
}
