I am using following HTML to create a three level inline list. First Level shows by default on page load. When I click on first level menu i.e. 'Courses' it expands and shows second level menus. But when I click on second level menus i.e. 'Computer Courses' or 'Civil Courses', they do not expand to show third level menus.
Thanks in advance for any help.
<ul class="nav navbar-nav">
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-
haspopup="true" aria-expanded="false">Courses <span class="caret"></span></a>
<ul class="dropdown-menu">
<li class="dropdown-submenu">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-
haspopup="true" aria-expanded="false" >Computer Courses<span class="caret"></span>
</a>
<ul class="dropdown-menu">
<li class="dropdown-submenu"><a href="#"><i class=" glyphicon glyphicon-menu-

</li>
<li class="dropdown-submenu"><a href="#"><i class=" glyphicon glyphicon-menu-

I'm not sure how twitter-bootstrap works exactly, but I can imagine having multiple <a> tags with href="#"s messes this up. Moreover, your html is not valid (you can have <ul> as a child of another <ul>) and perhaps wrapping a <ul> within an <a> is also not good practise.
Use javascript onclick functions for the expand behaviour, or dive a little deeper into twitter-bootstrap, in case they do support something like this.
P.S. Consult https://validator.w3.org/nu/#textarea to see what html is valid.

This is my first question to StackOverflow, so I'm sorry if it's a little wonky.
Anyway, I have a need to use a "back" or "close" link within a Bootstrap dropdown menu. It appears that the dropdown() function only appends the "open" class to the direct parent of the element with the "dropdown-toggle" class.
Anyone have any ideas? Here is my markup:
<li class="navbar__nav-item navbar__nav-dropdown dropdown">
<a class="navbar__nav-link navbar__dropdown-toggle dropdown-toggle" data-toggle="dropdown">News & Events</a>
<ul class="navbar__nav-dropdown-menu dropdown-menu">
<li class="navbar__header-menu-title">
<h6 class="navbar__header-menu-back ">
<a class="navbar__header-menu-back-link dropdown-toggle" data-toggle="dropdown">< Back</a>
</h6>
<h6 class="navbar__menu-title">
Title
</h6>
</li>
<li class="navbar__dropdown-menu-item">
<a class="navbar__dropdown-menu-link" href="component-library.html">Link1</a>
</li>
<li class="navbar__dropdown-menu-item">
<a class="navbar__dropdown-menu-link">Link2</a>
</li>
</ul>
I want user to be able to select everything within Morphological Transformation (Erosion, Dilation, Opening, Closing), but not 'Morphological Transformation' itself. Thank you for every answer!
HTML Code:
<div class="container">
<div class="row">
<hr>
<div class="dropdown">
<a id="dLabel" role="button" data-toggle="dropdown" class="btn btn-primary" data-target="#" href="/page.html">
Select Pre-Processing Method <span class="caret"></span>
</a>
<ul class="dropdown-menu multi-level" role="menu" aria-labelledby="dropdownMenu">
<li>Normalisation</li>
<li>Canny Edge Detection</li>
<li>Smoothing</li>
<li></li>
<li class="divider"></li>
...
<li class="dropdown-submenu">
<a tabindex="-1" href="#">Morphological Transformation</a>
<ul class="dropdown-menu">
<li><a>Erosion</a></li>
<li><a>Dilation</a></li>

You can disable anchor events and keep hover effects by using this:
.disabled-link:hover{
background: red;
}
.disabled-link:active{
pointer-events: none;
}

It is usable for all modern browsers:
click!
My Bootstrap menu doesn't show the submenu dropdown. Here's the code. I'm using Bootstrap 3. The "dropdown-submenu" class I believe should be the one to show the arrow and on click show the submenu ul.
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
Category
<span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li class="dropdown-submenu">

<ul class="dropdown-menu">
<li >

</li>
</ul>
</li>
<li >

</li>
<li >

<li class="dropdown-submenu">

Bootstrap 3.3.5 (current) documentation and Bootstrap 3.3.5 CSS file do not contain a definition for dropdown-submenu class.
It means that this class is redundant and does not affect the code at all (of course, if you haven't described it in your own CSS).
Here is the JS Fiddle Demo which works how it should work.
I have found a definition of dropdown-submenu in Bootstrap 2.3.2 but it looks like it is depricated now.
Here is the working JS Fiddle Demo with submenus with Bootstrap 2.3.2.
However, I highly recommend not to use an outdated library because of a single feature.
I am trying to build my first website using the bootstrap template and I cannot get the dropdown button in the nav bar to show anything or open. It will display everything the way I want it, but the "open" function of it isn't working properly for some reason.
Here is what I have in the HTML part:
<li div class="dropdown">
<a data-toggle="dropdown" href="#" class="dropdown-toggle" data-
toggle="dropdown">General Education <b class="caret"></b></a>
<ul class="dropdown-menu">
<li>Composition</li>
<li>American Institutions</li>
<li>Humanities</li>
<li>Physical Sciences</li>
<li>Quantitative Literacy</li>
<li>Fine Arts</li>
<li>Interdisciplinary</li>
<li>Social Sciences</li>
<li>Fine Arts</li>
</ul>
</li>
(I haven't updated all of the target links yet, for now most of them just show as a #)
and for the CSS I have:
.dropdown-toggle:active,
.open .dropdown-toggle {
outline: 0;
}
Please help!

I created a Bootstrap dropdown using this code:
<div class="dropdown" style="margin-bottom: 20px;">Ordered by
<a class="dropdown-toggle" data-toggle="dropdown" href="#"><span class="primary">Random</span></a>
<ul class="dropdown-menu" role="menu">
<li>Random</li>
<li>Earliest</li>
<li>Latest</li>
</ul>
post.
</div>
But as you can see, the dropdown isn't aligned with the link:
How can I get it to align, and if possible, also display the white triangle on top pointing to the link?
