How can I trigger an element to 'click' IF it is currently selected through tabbing on the keyboard?

I have an identical dropdown menu for each of 5 div boxes. I want to create functionality where when I navigate to one of these dropdown menus, that is via tabbing to the chevron down icon shown in the code below, I can expand and collapse the menu that is currently in focus.
<div class="appExperience small-tile">
<div class="blue-bar">
<h2 class="tile-header">APPLICATION EXPERIENCE</h2>
<span class="dropdown hidden-xs">
<i class="tcm-chevron glyphicon glyphicon-chevron-down expand-icon dropdown-toggle"
role="button"
aria-labledby="Expand Application Experience Summary Dropdown Menu"
ng-src="{{dropdown_appExperience}}"
data-toggle="dropdown"
tabindex="0"
alt="Expand Application Experience Summary Dropdown Menu"></i>
<ul class="dropdown-menu appExperience tileContextMenu">
<li>
List Item 1
</li>
<li>
List Item 2
</li>
...
I have tried this following:
$(window).on("keydown", function() {
$('.glyphicon-chevron-down option:selected').trigger("click")
});
Edit, this is another new attempt
if ($(".glyphicon-chevron-down").is(":focus")) {
$(window).on("keydown", function() {
$(".glyphicon-chevron-down").trigger("click")
});
}
Newest attempt
I'm getting close, but the following code suggests that trigger is not a function?
$(window).on("keydown", function() {
console.log(document.activeElement);
console.log($(".glyphicon-chevron-down")[0]);
if (document.activeElement == $(".glyphicon-chevron-down")[0]) {
console.log("activeElement is recognized!")
console.log($(".glyphicon-chevron-down")[0]);
$(".glyphicon-chevron-down")[0].trigger("click");
}
});

I do not think you need to track the tab event as: $(".glyphicon-chevron-down").focus(function(){}); , would do the job without the extra event for tracking the user "tab" button pressing.
Try:
$(".glyphicon-chevron-down").focus( function(){
//do your logic here
//e.g
$( this ).trigger("click"); // if this should expand on hover then bind hover event
// hover event
$( this ).trigger("mouseover");
});

This will give you the element that is currently in focus. You can then work with it according to your preference.
$(window).on("keyup", function() {
console.log(document.activeElement);
});

Having different click areas on sidenav

I am using bootstrap and in that I am using side nav to serve collapsible list on the left side of the page. Below is my code.
<ul class="nav navbar-nav side-nav">
<li>
<a class="active" href="#" onclick="loadelementsonpage(); return false" data-toggle="collapse" data-target="#licomp1">
<i class="fa fa-fw fa-arrow-v"></i>Parent1
</a>
<ul id="licomp1" class="collapse">
<li>Child1</li>
<li>Child2</li>
<li>Child3</li>
</ul>
</li>
</ul>
Instead of fixed <i class="fa fa-fw fa-arrow-v"></i> I want to use toggle plus and minus. As it is shown in code, I am calling one function when parent1 is clicked. But when I try to expand the ul, the function loadelementsonpage() is called everytime. So, I want list to collapse only when that toggle image is clicked. In the same way I want to call loadelementsonpage() only when the outer area of that toggle image is clicked. I changed this data-toggle and data-target to i class, but the problem is the function is still getting called and if I move the i class out of a tag, the style is messed up.
So can someone please shed some light on how to have different click areas on the parent li? One is for collapse and another is for calling function to load right side content page.
P.S: Trying to implement this http://cssmenumaker.com/menu/modern-jquery-accordion-menu kind of side nav list where + or - should be clickable for only expanding and collapsing. Please click on build online in that link to see the side nav. Other area(apart from + and - icons) should act as link href to load the page.

Instead of giving the data-toggle attribute to the anchor, give it to the icon element so that toggle works only for the icon. You can use the classes here for plus and minus and toggle between the classes glyphicon-plus and glyphicon-minus
<a class="active" href="#">
<span data-toggle="collapse" class="glyphicon glyphicon-plus" data-target="#licomp1"></span>Parent1
</a>
$('.side-nav a span').on('click', function () {
$(this).toggleClass('glyphicon-plus glyphicon-minus');
});
Now on click of the anchor you can check if the element is A and if true then only call the custom function loadelementsonpage.
$('.side-nav a').on('click', function (e) {
console.log(e.target.tagName);
if (e.target.tagName == "A") {
loadelementsonpage();
return true;
}
})
function loadelementsonpage() {
alert('Load elements on page');
}
See fiddle

jsbin demo
Remove the inline JS you have in your HTML:
<a class="active" href="#" data-toggle="collapse" data-target="#licomp1">
<i class="fa fa-fw fa-arrow-v"></i>Parent1
</a>
And simply add this to your jQuery:
function loadelementsonpage(){
alert("LOADED ELEMENTS! YIIHA"); // Or whatever goes here
}
$(".side-nav").on("click", "a[data-target]", function(e) {
e.preventDefault(); // Prevent default Browser anchor-click behavior
if( !$(e.target).hasClass("fa") ){ // If the clicked el. target was not `.fa`
// means it was the parent `a` to get the click event. Therefore...
e.stopPropagation(); // prevent the click to propagate
// to underneath layers triggering stuff and...
return loadelementsonpage(); // execute (return) our desired function.
}
});
(Make sure you have it in document.ready function)
What the above does

Proof of concept:
function loadelementsonpage(target) {
// example stuff
$(target).toggle();
}
$(".side-nav").on("click", "a[data-toggle]", function(event) {
event.preventDefault(); // Prevent default Browser anchor-click behavior
var icon = $(event.target).find('.collapseIcon');
if (icon.text() === '+') {
icon.text('-');
} else {
icon.text('+');
}
loadelementsonpage(event.target.getAttribute('data-target'));
return false;
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="nav navbar-nav side-nav">
<li>
<a class="active" href="#" data-toggle="collapse" data-target="#licomp1">
<span class="collapseIcon">-</span> Parent1
</a>
<ul id="licomp1" class="collapse">
<li>Child1
</li>
<li>Child2
</li>
<li>Child3
</li>
</ul>

</ul>

Avoid dropdown menu close on click inside

I have a Twitter Bootstrap dropdown menu. As all Twitter Bootstrap users know, the dropdown menu closes on click (even clicking inside it).
To avoid this, I can easily attach a click event handler on the dropdown menu and simply add the famous event.stopPropagation().
<ul class="nav navbar-nav">
<li class="dropdown mega-dropdown">
<a href="javascript:;" class="dropdown-toggle" data-toggle="dropdown">
<i class="fa fa-list-alt"></i> Menu item 1
<span class="fa fa-chevron-down pull-right"></span>
</a>
<ul class="dropdown-menu mega-dropdown-menu">
<li>
<div id="carousel" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<li data-slide-to="0" data-target="#carousel"></li>
<li class="active" data-slide-to="1" data-target="#carousel"></li>
</ol>
<div class="carousel-inner">
<div class="item">
<img alt="" class="img-rounded" src="img1.jpg">
</div>
<div class="item active">
<img alt="" class="img-rounded" src="img2.jpg">
</div>
</div>
<a data-slide="prev" role="button" href="#carousel"
class="left carousel-control">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a data-slide="next" role="button" href="#carousel"
class="right carousel-control">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
</div>
</li>
</ul>
</li>
</ul>
This looks easy and a very common behavior, however, and since carousel-controls (as well as carousel indicators) event handlers are delegated to the document object, the click event on these elements (prev/next controls, ...) will be “ignored”.
$('ul.dropdown-menu.mega-dropdown-menu').on('click', function(event){
// The event won't be propagated up to the document NODE and
// therefore delegated events won't be fired
event.stopPropagation();
});
Relying on Twitter Bootstrap dropdown hide/hidden events is not a solution for the following reasons:
The provided event object for both event handlers does not give reference to the clicked element
I don't have control over the dropdown menu content so adding a flag class or attribute is not possible
This fiddle is the normal behavior and this fiddle is with event.stopPropagation() added.
Update
Thanks to Roman for his answer. I also found an answer that you can find below.

This should help as well
$(document).on('click', 'someyourContainer .dropdown-menu', function (e) {
e.stopPropagation();
});

Removing the data attribute data-toggle="dropdown" and implementing the open/close of the dropdown can be a solution.
First by handling the click on the link to open/close the dropdown like this :
$('li.dropdown.mega-dropdown a').on('click', function (event) {
$(this).parent().toggleClass('open');
});
and then listening the clicks outside of the dropdown to close it like this :
$('body').on('click', function (e) {
if (!$('li.dropdown.mega-dropdown').is(e.target)
&& $('li.dropdown.mega-dropdown').has(e.target).length === 0
&& $('.open').has(e.target).length === 0
) {
$('li.dropdown.mega-dropdown').removeClass('open');
}
});
Here is the demo :
http://jsfiddle.net/RomaLefrancois/hh81rhcm/2/

The absolute best answer is to put a form tag after the class dropdown-menu
so your code is
<ul class="dropdown-menu">
<form>
<li>
<div class="menu-item">bla bla bla</div>
</li>
</form>
</ul>

Bootstrap provides the following function:
| This event is fired immediately when the hide instance method
hide.bs.dropdown | has been called. The toggling anchor element is available as the
| relatedTarget property of the event.
Therefore, implementing this function should be able to disable the dropdown from closing.
$('#myDropdown').on('hide.bs.dropdown', function (e) {
var target = $(e.clickEvent.target);
if(target.hasClass("keepopen") || target.parents(".keepopen").length){
return false; // returning false should stop the dropdown from hiding.
}else{
return true;
}
});

This might help:
$("dropdownmenuname").click(function(e){
e.stopPropagation();
})

I just add onclick event like below to not close dropdown-menu.
<div class="dropdown-menu dropdown-menu-right" onclick="event.stopPropagation()" aria-labelledby="triggerId">

I also found a solution.
Assuming that the Twitter Bootstrap Components related events handlers are delegated to the document object, I loop the attached handlers and check if the current clicked element (or one of its parents) is concerned by a delegated event.
$('ul.dropdown-menu.mega-dropdown-menu').on('click', function(event){
var events = $._data(document, 'events') || {};
events = events.click || [];
for(var i = 0; i < events.length; i++) {
if(events[i].selector) {
//Check if the clicked element matches the event selector
if($(event.target).is(events[i].selector)) {
events[i].handler.call(event.target, event);
}
// Check if any of the clicked element parents matches the
// delegated event selector (Emulating propagation)
$(event.target).parents(events[i].selector).each(function(){
events[i].handler.call(this, event);
});
}
}
event.stopPropagation(); //Always stop propagation
});
Hope it helps any one looking for a similar solution.
Thank you all for your help.

In the new Bootstrap 5 the solution is trivially simple.
Quote from the documentation page:
By default, the dropdown menu is closed when
clicking inside or outside the dropdown menu. You can use the
autoClose option to change this behavior of the dropdown.
In addition to the default behavior, we have 3 options available here:
Clickable outside: data-bs-auto-close="outside"
Clickable inside: data-bs-auto-close="inside"
Manual close: data-bs-auto-close="false"
E.g.:
<div class="btn-group">
<button class="btn btn-secondary dropdown-toggle" data-bs-auto-close="inside" type="button" id="dropdownMenuClickableInside" data-bs-toggle="dropdown" aria-expanded="false">
Clickable inside
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenuClickableInside">
<li><a class="dropdown-item" href="#">Menu item</a></li>
<li><a class="dropdown-item" href="#">Menu item</a></li>
<li><a class="dropdown-item" href="#">Menu item</a></li>
</ul>
</div>
More info: https://getbootstrap.com/docs/5.1/components/dropdowns/#auto-close-behavior

$('body').on("click", ".dropdown-menu", function (e) {
$(this).parent().is(".open") && e.stopPropagation();
});
This may work for any conditions.

I tried this simple thing and it worked like a charm.
I changed the dropdown-menu element from <div> to <form> and it worked well.
<div class="nav-item dropdown" >
<a href="javascript:;" class="nav-link dropdown-toggle" data-toggle="dropdown">
Click to open dropdown
</a>
<form class="dropdown-menu ">
<ul class="list-group text-black">
<li class="list-group-item" >
</li>
<li class="list-group-item" >
</li>
</ul>
</form>

</a>
<form class="dropdown-menu ">
<ul class="list-group text-black">
<li class="list-group-item" >
List Item 1
</li>
<li class="list-group-item" >
LI 2<input class="form-control" />
</li>
<li class="list-group-item" >
List Item 3
</li>
</ul>
</form>

jQuery:
<script>
$(document).on('click.bs.dropdown.data-api', '.dropdown.keep-inside-clicks-open', function (e) {
e.stopPropagation();
});
</script>
HTML:
<div class="dropdown keep-inside-clicks-open">

I modified #Vartan's answer to make it work with Bootstrap 4.3. His solution doesn't work anymore with the latest version as target property always returns dropdown's root div no matter where the click was placed.
Here is the code:
$('.dropdown-keep-open').on('hide.bs.dropdown', function (e) {
if (!e.clickEvent) {
// There is no `clickEvent` property in the `e` object when the `button` (or any other trigger) is clicked.
// What we usually want to happen in such situations is to hide the dropdown so we let it hide.
return true;
}
var target = $(e.clickEvent.target);
return !(target.hasClass('dropdown-keep-open') || target.parents('.dropdown-keep-open').length);
});
<div class="dropdown dropdown-keep-open">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown button
</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</div>

$('body').on("click", ".dropdown-menu", function (e) {
$(this).parent().is(".show") && e.stopPropagation();
});

Like for instance Bootstrap 4 Alpha has this Menu Event. Why not use?
// PREVENT INSIDE MEGA DROPDOWN
$('.dropdown-menu').on("click.bs.dropdown", function (e) {
e.stopPropagation();
e.preventDefault();
});

You can also use form tag. Example:
<div class="dropdown-menu">
<form>
Anything inside this wont close the dropdown!
<button class="btn btn-primary" type="button" value="Click me!"/>
</form>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Clik this and the dropdown will be closed</a>
<a class="dropdown-item" href="#">This too</a>
</div>

Bootstrap 5
If anyone comes to this via Google wanting a Bootstrap 5 version like I was, it's built in by adding data-bs-auto-close="outside". Note the option is autoClose but when passing as a data attribute the camelcasing is removed & separated by a dash.
I have a collapse widget in a dropdown & adding data-bs-auto-close="outside" to the parent data-bs-toggle="dropdown" trigger keeps the dropdown open while the collapse is toggled.
See official Bootstrap docs: https://getbootstrap.com/docs/5.1/components/dropdowns/#options
And this codepen for example code (not my pen): https://codepen.io/SitePoint/pen/BaReWGe

I've got a similar problem recently and tried different ways to solve it with removing the data attribute data-toggle="dropdown" and listening click with event.stopPropagation() calling.
The second way looks more preferable. Also Bootstrap developers use this way.
In the source file I found initialization of the dropdown elements:
// APPLY TO STANDARD DROPDOWN ELEMENTS
$(document)
.on('click.bs.dropdown.data-api', clearMenus)
.on('click.bs.dropdown.data-api', '.dropdown form', function (e) { e.stopPropagation() })
.on('click.bs.dropdown.data-api', toggle, Dropdown.prototype.toggle)
.on('keydown.bs.dropdown.data-api', toggle, Dropdown.prototype.keydown)
.on('keydown.bs.dropdown.data-api', '.dropdown-menu', Dropdown.prototype.keydown)
}(jQuery);
So, this line:
.on('click.bs.dropdown.data-api', '.dropdown form', function (e) { e.stopPropagation() })
suggests you can put a form element inside the container with class .dropdown to avoid closing the dropdown menu.

Bootstrap has solved this problem themselves in their support for <form> tags in dropdowns. Their solution is quite graspable and you can read it here: https://github.com/twbs/bootstrap/blob/v4-dev/js/src/dropdown.js
It boils down to preventing propagation at the document element and doing so only for events of type 'click.bs.dropdown.data-api' that match the selector '.dropdown .your-custom-class-for-keep-open-on-click-elements'.
Or in code
$(document).on('click.bs.dropdown.data-api', '.dropdown .keep-open-on-click', (event) => {
event.stopPropagation();
});

You could simply execute event.stopPropagation on click event of the links themselves.
Something like this.
$(".dropdown-menu a").click((event) => {
event.stopPropagation()
let url = event.target.href
//Do something with the url or any other logic you wish
})
Edit: If someone saw this answer and is using react, it will not work.
React handle the javascript events differently and by the time your react event handler is being called, the event has already been fired and propagated. To overcome that you should attach the event manually like that
handleMenuClick(event) {
event.stopPropagation()
let menu_item = event.target
//implement your logic here.
}
componentDidMount() {
document.getElementsByClassName("dropdown-menu")[0].addEventListener(
"click", this.handleMenuClick.bind(this), false)
}
}

You can stop click on the dropdown from propagating and then manually reimplement the carousel controls using carousel javascript methods.
$('ul.dropdown-menu.mega-dropdown-menu').on('click', function(event) {
event.stopPropagation();
});
$('a.left').click(function () {
$('#carousel').carousel('prev');
});
$('a.right').click(function () {
$('#carousel').carousel('next');
});
$('ol.carousel-indicators li').click(function (event) {
var index = $(this).data("slide-to");
$('#carousel').carousel(index);
});
Here is the jsfiddle.

demo: http://jsfiddle.net/4y8tLgcp/
$('ul.nav.navbar-nav').on('click.bs.dropdown', function(e){
var $a = $(e.target), is_a = $a.is('.is_a');
if($a.hasClass('dropdown-toggle')){
$('ul.dropdown-menu', this).toggle(!is_a);
$a.toggleClass('is_a', !is_a);
}
}).on('mouseleave', function(){
$('ul.dropdown-menu',this).hide();
$('.is_a', this).removeClass('is_a');
});
i have updated it once again to be the smartest and functional as possible. it now close when you hover outside the nav, remaining open while you are inside it. simply perfect.

I know there already is a previous answer suggesting to use a form but the markup provided is not correct/ideal. Here's the easiest solution, no javascript needed at all and it doesn't break your dropdown. Works with Bootstrap 4.
<form class="dropdown-item">
<!-- Your elements go here -->
</form>

I know this question was specifically for jQuery, but for anyone using AngularJS that has this problem you can create a directive that handles this:
angular.module('app').directive('dropdownPreventClose', function() {
return {
restrict: 'A',
link: function(scope, element, attrs) {
element.on('click', function(e) {
e.stopPropagation(); //prevent the default behavior of closing the dropdown-menu
});
}
};
});
Then just add the attribute dropdown-prevent-close to your element that is triggering the menu to close, and it should prevent it. For me, it was a select element that automatically closed the menu:
<div class="dropdown-menu">
<select dropdown-prevent-close name="myInput" id="myInput" ng-model="myModel">
<option value="">Select Me</option>
</select>
</div>

With Angular2 Bootstrap, you can use nonInput for most scenarios:
<div dropdown autoClose="nonInput">
nonInput - (default) automatically closes the dropdown when any of its elements is clicked — as long as the clicked element is not an input or a textarea.
https://valor-software.com/ng2-bootstrap/#/dropdowns

[Bootstrap 4 Alpha 6][Rails]
For rails developer, e.stopPropagation() will lead to undesirable behavior for link_to with data-method not equal to get since it will by default return all your request as get.
To remedy this problem, I suggest this solution, which is universal
$('.dropdown .dropdown-menu').on('click.bs.dropdown', function() {
return $('.dropdown').one('hide.bs.dropdown', function() {
return false;
});
});
$('.dropdown .dropdown-menu').on('click.bs.dropdown', function() {
return $('.dropdown').one('hide.bs.dropdown', function() {
return false;
});
});

This helped me,
$('.dropdown-menu').on('click', function (e) {
if ($(this).parent().is(".open")) {
var target = $(e.target);
if (target.hasClass("keepopen") || target.parents(".keepopen").length){
return false;
}else{
return true;
}
}
});
Your drop down menu element needs to be like this, (take a note of the classes dropdown-menu and keepopen.
<ul role="menu" class="dropdown-menu topmenu-menu eserv_top_notifications keepopen">
The above code prevents biding on the whole <body>, instead to the specfic element with the class dropdown-menu.
Hope this helps someone.
Thanks.

The simplest working solution for me is:
adding keep-open class to elements that should not cause dropdown closing
and this piece of code do the rest:
$('.dropdown').on('click', function(e) {
var target = $(e.target);
var dropdown = target.closest('.dropdown');
return !dropdown.hasClass('open') || !target.hasClass('keep-open');
});

I've found none of the solutions worked as I would like using default bootstrap nav.
Here is my solution to this problem:
$(document).on('hide.bs.dropdown', function (e) {
if ($(e.currentTarget.activeElement).hasClass('dropdown-toggle')) {
$(e.relatedTarget).parent().removeClass('open');
return true;
}
return false;
});

Instead of writing some javascript or jquery code(reinventing the wheel). The above scenario can be managed by bootstrap auto-close option.
You can provide either of the values to auto-close:
always - (Default) automatically closes the dropdown when any of its elements is clicked.
outsideClick - closes the dropdown automatically only when the user clicks any element outside the dropdown.
disabled - disables the auto close
Take a look at the following plunkr :
http://plnkr.co/edit/gnU8M2fqlE0GscUQtCWa?p=preview
Set
uib-dropdown auto-close="disabled"
Hope this helps :)

In .dropdown content put the .keep-open class on any label like so:
$('.dropdown').on('click', function (e) {
var target = $(e.target);
var dropdown = target.closest('.dropdown');
if (target.hasClass('keep-open')) {
$(dropdown).addClass('keep-open');
} else {
$(dropdown).removeClass('keep-open');
}
});
$(document).on('hide.bs.dropdown', function (e) {
var target = $(e.target);
if ($(target).is('.keep-open')) {
return false
}
});
The previous cases avoided the events related to the container objects, now the container inherits the class keep-open and check before being closed.

I'm trying to create a <select> replacement that mimics all of <select>s functionality, but can be custom styled and use icons.
My problem is i can't seem to get focusout to hide the options. As of now focusout trigger the same thing when tabbing/arrowing the list items as when you tab/click outside.
Generated HTML
(idd = icon-drop-down)
<div class="idd-wrapper">
<button>Select text</button>
<ul id="idd-ul">
<li>
<a href="#">
<span class="icon-apple"></span>
<span class="idd-text">Apple</span>
</a>
</li>
[...]
</ul>
</div>
jQuery
$('#idd-ul a').each(function(e) {
$(this).on('focusout', function(e) {
//Trying different if statements...
if($('#idd-ul a').is(':focus')){
//do nothing
} else {
$('#idd-ul').hide();
}
});
});

Prevent the disappear of Dropdown menu using bootstrapDropdown when clicking on the list

I am using using bootstrap-dropdown to generate a Dropdown menu. I would like to prevent the disappearing of the menu when click on it.
I have implemented the following code, but it does not work. Any idea how to fix it?
HTML
<li class="dropdown notification">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
<span class="notification-label label label-info">
<i class="icon-inbox icon-white"></i>
<span class="notification-number">{{ unread_notifications }}</span>
</span>
</a>
<ul class="dropdown-menu notification-list"></ul>
</li>
JS
events: {
'click ul.notification-list': 'onClickNotification'
},
onClickNotification: function (e) {
e.preventDefault();
console.log(e);
},

Did you try with event.stopPropagation?
onClickNotification: function (e) {
e.stopPropagation();
console.log(e)
},

If you want to disable all auto closing of the dropdown you can just disable the listener
$('html').off('click.dropdown')
