Menu
I'm using bootstrap 3 for desktop, and only using nav, rather than navbar.
How to make a dropdown on hover and click?
<ul id="nav" class="nav nav-pills clearfix right" role="tablist">
<li><a href="#">menuA</a></li>
<li><a href="#">menuB</a></li>
<li class="dropdown"><a href="#" class="dropdown-toggle" data-toggle="dropdown">menuC</a>
<ul id="products-menu" class="dropdown-menu clearfix" role="menu">
<li><a href="">A</a></li>
<li><a href="">B</a></li>
<li><a href="">C</a></li>
<li><a href="">D</a></li>
</ul>
</li>
<li><a href="#">menuD</a></li>
<li><a href="#">menuE</a></li>
</ul>

Answer: Use the jQuery hover() method By default, to open or display the dropdown menu in Bootstrap you have to click on the trigger element. However, if you want to show the dropdown on mouseover instead of click you can do it with little customization using the CSS and jQuery.
Example Explained. Use any element to open the dropdown menu, e.g. a <button>, <a> or <p> element. Use a container element (like <div>) to create the dropdown menu and add the dropdown links inside it. Wrap a <div> element around the button and the <div> to position the dropdown menu correctly with CSS.
Dropdowns are toggleable, contextual overlays for displaying lists of links and more. They're made interactive with the included Bootstrap dropdown JavaScript plugin. They're toggled by clicking, not by hovering; this is an intentional design decision.
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.
How to open Bootstrap dropdown menu on hover rather than click. Answer: Use the jQuery hover() method. By default, to open or display the dropdown menu in Bootstrap you have to click on the trigger element.
Steps to create simple hover navbar It is better to create hover effect only for desktop screens. Use media query @media all and (min-width: 992px) { // CSScode } Hide dropdown menu by adding display:none. Add pseudo-class :hoverto nav-item and add class display:block Note: bootstrap has margin-topon dropdown-menuelements.
To add buttons inside the navbar, add the .navbar-btn class on a Bootstrap button: To add form elements inside the navbar, add the .navbar-form class to a form element and add an input (s). Note that we have added a .form-group class to the div container holding the input.
The short answer is: use the jQuery hover () with the addClass () to display the dropdown menu on mouse hover. You can also use the jQuery removeClass () to hide the menu on mouse out.
With this simple CSS.
.dropdown:hover .dropdown-menu {
display: block;

<ul id="nav" class="nav nav-pills clearfix right" role="tablist">
<li><a href="#">menuA</a></li>
<li><a href="#">menuB</a></li>
<li class="dropdown"><a href="#" class="dropdown-toggle" data-toggle="dropdown">menuC</a>
<ul id="products-menu" class="dropdown-menu clearfix" role="menu">

<li><a href="">B</a></li>
<li><a href="">C</a></li>
<li><a href="">D</a></li>
</ul>
</li>
<li><a href="#">menuD</a></li>
<li><a href="#">menuE</a></li>
</ul>Use this script, since you are using jquery for bootstrap anyway. Also give additional classes (preferably ids) to jquery selector so it doesn't affect other dropdowns in your page .
$(function(){
$("#nav .dropdown").hover(
function() {
$('#products-menu.dropdown-menu', this).stop( true, true ).fadeIn("fast");
$(this).toggleClass('open');
},
function() {
$('#products-menu.dropdown-menu', this).stop( true, true ).fadeOut("fast");
$(this).toggleClass('open');
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<ul id="nav" class="nav nav-pills clearfix right" role="tablist">
<li><a href="#">menuA</a></li>
<li><a href="#">menuB</a></li>
<li class="dropdown"><a href="#" class="dropdown-toggle" data-toggle="dropdown">menuC</a>
<ul id="products-menu" class="dropdown-menu clearfix" role="menu">
<li><a href="">A</a></li>
<li><a href="">B</a></li>
<li><a href="">C</a></li>
<li><a href="">D</a></li>
</ul>
</li>
<li><a href="#">menuD</a></li>
<li><a href="#">menuE</a></li>
</ul>Above solutions are not mobile friendly so here is the solution I am proposing
Detect if its not touch device and that the navbar-toggle (hamburger menu) is not visible and make the menu item hoverable
Also made tne margin-top 0 because the gap between the navbar and the menu in some browser will not let you hover to the subitems
As a bonus you can make the menu parent link clickable by uncommenting the commented line
$(function(){
function is_touch_device() {
return 'ontouchstart' in window // works on most browsers
|| navigator.maxTouchPoints; // works on IE10/11 and Surface
};
if(!is_touch_device() && $('.navbar-toggle:hidden')){
$('.dropdown-menu', this).css('margin-top',0);
$('.dropdown').hover(function(){
$('.dropdown-toggle', this).trigger('click');
//uncomment below to make the parent item clickable
//$('.dropdown-toggle', this).toggleClass("disabled");
});
}
