[html] Bootstrap - dropdown menu not working?

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!

JS:

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

HTML:

<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><a href="#">Profile</a></li>
                <li class="active"><a href="#">Statistics</a></li>
                <li><a href="#">Reader</a></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><a href="#">Action</a></li>
                        <li><a href="#">Another action</a></li>
                        <li><a href="#">Something else here</a></li>
                        <li class="divider"></li>
                        <li><a href="#">Separated link</a></li>
                    </ul>
                </li>

            </ul>


        </div>
    </div>
</div>

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>

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

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">
                        <a href="#" class="dropdown-toggle" data-toggle="dropdown">Theme <b class="caret"></b></a>
                        <ul id="theme" class="dropdown-menu" role="menu">
                            <li><a href="#">Amelia</a></li>
                            <li><a href="#">Cerulean</a></li>
                            <li><a href="#">Cyborg</a></li>
                            <li><a href="#">Cosmo</a></li>
                            <li><a href="#">Darkly</a></li>
                            <li><a href="#">Flatly</a></li>
                            <li><a href="#">Lumen</a></li>
                            <li><a href="#">Simplex</a></li>
                            <li><a href="#">Slate</a></li>
                            <li><a href="#">Spacelab</a></li>
                            <li><a href="#">Superhero</a></li>
                            <li><a href="#">United</a></li>
                            <li><a href="#">Yeti</a></li>
                        </ul>
                    </li>
                </ul>

Javascript

$('#theme li').click(function () {
        //alert('item: ' + $(this).text());
        switch_style($(this).text());
    });

Hope it helps someone

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

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>

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.

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

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>

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();
        }
    }

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>
