Bootstrap dropdown submenu closing upstream submenu

I have a two-level dropdown that's working great, but when I add another level, the JS seems to be removing the open class from the previous submenu, which means that the desired third-level menu can't be seen, even though it does get the open class added.
I've tracked it down to this JS:
$(function() {
$('li.dropdown-submenu').on('click', function(event) {
event.stopPropagation();
if ($(this).hasClass('open')){
$(this).removeClass('open');
} else {
$('li.dropdown-submenu').removeClass('open');
$(this).addClass('open');
}
});
});
This is, I think, doing the undesired closing of the previous submenu. The HTML is very similar to this example.
Using an adaptation of the JS from that example, I get the third level, but then any given open submenu doesn't automatically close when clicking another submenu.
$(document).ready(function(){
$('.dropdown-submenu a').on("click", function(e){
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
});
});
Need the best of both here!

I think you almost had it, you just needed to look for the different clicks.
The approach I took below was to handle all a clicks but then check to see if it had a class of test which then followed your code verbatim or else, if it didn't have a class of test it then hides all the submenus and goes to it's default href.
<script>
$(document).ready(function(){
$('.dropdown-submenu a').on("click", function(e){
if ($(this).hasClass('test')) {
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
} else {
$('.dropdown-submenu ul').hide();
}
});
});
</script>

Maybe this is what are you looking for.
This code to close submenu when clicking another submenu.
Javascript
$(document).ready(function(){
$('.dropdown-submenu a.test').on("click", function(e){
/* This is to hide all dropdown-menu children if the parent(dropdown-submenu) in the element have been clicked */
$(this).next('ul').find('.dropdown-menu').each(function(){
$(this).hide();
});
/* This is to find another dropdown-menu have has been opened and hide its submenu */
var xw = $(this);
$(this).closest(".dropdown-menu").find('.dropdown-submenu a.test').not(xw).each(function(){
if($(this).next("ul").is(":visible")){
$(this).next("ul").hide();
}
});
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
});
});
And JSFiddle example : https://jsfiddle.net/synz/vasho634/

I hope this is what you want. Here is the Solution, Not Full Proof but upto that extent whre you want
$(document).ready(function(){
$('.dropdown-submenu a.test').on("click", function(e){
siblingUl = $(this).parent().siblings("li.dropdown-submenu").children("ul").css("display");
if(siblingUl == "block"){
$(this).parent().siblings("li.dropdown-submenu").children("ul").toggle();
}
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
});
});

How to close a sidebar when clicking outside?

I have a right sidebar appearing when this function its called
var toggleSidebar = function() {
$('#sidebar .arrow-box').click(function() {
if (s === 0) {
s = 1;
$('#sidebar').css('left', '0');
$('#sidebar .arrow').removeClass('dir-two');
$('#sidebar .arrow').addClass('dir-one');
$('#content').css('padding-left', '0');
} else {
s = 0;
$('#sidebar').css('left', '-300px');
$('#sidebar .arrow').addClass('dir-two');
$('#sidebar .arrow').removeClass('dir-one');
$('#content').css('padding-left', '300px');
}
});
};
but as you see I can open and close that sidebar only when clicking on that specific element, what should I do in order to close it when I click outside?
And just in case: as per UX I am not able to use a dark background in the whole view when the sidebar comes up.

Test the target of the click. If it does not match the target you want to close, then close it. All the other elements are children of the body - so clicking anywhere outside of the panel will retrieve a click target.
$sidebar = $('#sidebar');
$( "body" ).click(function( event ) {
var a = event.target;
if(a === $sidebar){
//close the sidebar
//you may also want to test if it is actually open before calling the close function.
}
});

Take a look at this:
How do I detect a click outside an element?
$('html').click(function() {
// Hide the sidebar
});
$('#sidebar').click(function(event){
event.stopPropagation(); // prevents executing the above event
});

I would do it like this... (DEMO HERE)
sideBarOpen=false;
function openSidebar(){
sideBarOpen = true;
$('#sidebar').css('margin-left', '0');
$('#sidebar .arrow').removeClass('dir-two');
$('#sidebar .arrow').addClass('dir-one');
$('#content').css('padding-left', '0');
}
function closeSidebar(){
sideBarOpen=false;
$('#sidebar').css('margin-left', '-300px');
$('#sidebar .arrow').addClass('dir-two');
$('#sidebar .arrow').removeClass('dir-one');
$('#content').css('padding-left', '300px');
}
$( document ).click(function( event ) {
var target = $( event.target );
if(sideBarOpen){
closeSideBar();
} else {
if(target.is( '#sidebar' )){
openSideBar();
}
}
});
This will close it if the user clicks anywhere, but open it, if the user clicks the sidebar
UPDATE
If you want to also be able to click on the stuff inside the sidebar
Just give them a class, and add to the target.is check.
Example for links inside the bar
<a href='#' class='menuLinks'>Test Link</a>
Then your click handler
if(target.is( '#sidebar' ) || target.is('.menuLinks')){
openSideBar();
} else {
if(sideBarOpen){
closeSideBar();
}

Just detect clicks on an element that encompasses the page. And prevent clicks on the sidebar from bubbling up to that element.
$("body").click(function () {
toggleSidebar();
});
$("#sidebar").click(function (e) {
e.stopPropagation();
});

Add/remove class on right click

I'm trying to add a class on right-click of an element and then remove it when anything else on the page is clicked.
I'm using jQuery.
My function is this so far:
$(".classElement").live('mousedown', function(e) {
if( (e.which == 3) ) {
$(".classElement").addClass("active");
}
e.preventDefault();
}).live('contextmenu', function(e){
e.preventDefault();
});
However, this adds the "active" class to all ".classElement" in the doc, rather than the individual one being clicked. I want to only add the class to the element being clicked.
Also, how can I remove the class when anything else is clicked?

You can removClass active on click of body element, but for this you have to stop event propagation when you are clicking on current element.
$(document).on('mousedown','.classElement', function(e) {
e.preventDefault();
if( (e.which == 3) ) {
$(this).addClass("active");
}
e.stopPropagation();
}).on('contextmenu','.classElement', function(e){
e.preventDefault();
});
$(document.body).click(function(){
$(".classElement").removeClass("active");
});

You can use $(this) to target current clicked element, so you can do:
$(this).addClass("active");
instead of:
$(".classElement").addClass("active");
Also, since .live() was removed since version 1.9, you should use .on() instead.

to target specific element:
$(this).addClass("active");
and to remove it when anything else is clicked, add this:
$(window).one("click", function(){
$(this).removeClass("active");
});
This adds a one time only click event listener to the window.

Use this code
$(".classElement").live('contextmenu', function(e){
e.preventDefault();
if( (e.which == 3) ) {
$(this).addClass("active");
}
});
and then remove class on document click
$(document).click(function(){
$(".classElement").removeClass("active");
});

jQuery Accordion arrow icons with seperate close button

I've got an accordion with arrow icons indicating when a section is open and closed. Once the accordion is opened the arrow points down showing the content below it.
However I've created a close button that gets appended into each section. This sits at the bottom of every section in the accordion.
I want it so that once the close button is pressed the arrow changes it's state back to closed.
$(function() {
$('#accordion h3').each(function(){
var $set = $(this).nextUntil("h3");
$set.wrapAll('<div />');
});
$('#accordion').accordion({ collapsible:true, active:true, heightStyle:"content", disabled:true, animated: false});
$('.ui-accordion-header').bind('click',function(){
theOffset = $(this).offset();
$(window).scrollTop(theOffset.top - 50);
});
$('#accordion h3.ui-accordion-header').click(function(){
var _this = $(this);
$('.ui-accordion-header-icon', _this).toggleClass('ui-icon-triangle-1-e ui-icon-triangle-1-s');
_this.next().slideToggle();
return false;
});
$('.ui-accordion-content').append('Close<div class="clearfix"></div>');
$('.close').click(function(){
$(this).closest('.ui-accordion-content').toggleClass('ui-icon-triangle-1-s');
$(this).parent().slideUp('slow', function(){
$(window).scrollTop(theOffset.top - 50);
var hidecollapsebutton = true;
$('.ui-accordion-content').each(function(){
if($(this).css('display') == 'block')
{
hidecollapsebutton = false;
}
});
if(hidecollapsebutton)
{
$('.accordion-expand-all').show();
$('.accordion-collapse-all').hide();
}
});
return false;
})
});
Any help would be much appreciated. I can provide more information if it's needed. Thanks.

$('.close').click(function(){
$(this).closest('.ui-accordion-content').toggleClass('ui-icon-triangle-1-s');
As you could have found out yourself with a little simple debugging, $(this).closest('.ui-accordion-content') does not match any element here. (That’s because your close button is within div.ui-accordion-content, and the h3.ui-accordion-header is the previous sibling of that div element.)
Simple to fix: Go up to parent div (.ui-accordion-content), get previous h3 (.ui-accordion-header), and then the span (.ui-accordion-header-icon) element within it:
$(this).parents('.ui-accordion-content')
.prev('.ui-accordion-header')
.find('.ui-accordion-header-icon')
.removeClass('ui-icon-triangle-1-s')
.addClass('ui-icon-triangle-1-e');

I'd try changing click to on:
$(document).on("click", ".close", function(){
//change arrow state
});
It's because not every .close element exist as you binding click event.

click elsewhere

i have problem with click event. click to another element with event(click), doesn't count like click elsewhere. I want active one element or none.
demo: http://jsfiddle.net/WP4RH/
code:
$('span').click(function(){
var $this = $(this);
if($this.hasClass('active')){
$this.removeClass('active')}
else $this.addClass('active');
$('div').click(function(){
if (!$this.has(this).length) {
$this.removeClass('active');
}
});
return false;
});

Add this at the beginning of your span event handler:
$('.active').removeClass('active');
Demo
This is assuming that you want multiple clicks on the same span to retain active. If you don't want that, then let me know and I can modify the code.
​

For starters, You should move the div handler outside and then removeClass based on div element.
$('span').click(function(e) {
e.stopPropagation();
$(this).parent().find('span').removeClass('active');
$(this).toggleClass('active');
});
$('div').click(function() {
$(this).find('span').removeClass('active');
});
DEMO: http://jsfiddle.net/WP4RH/1/

Don't bind a click handler inside a click handler, just check if the target is the div or the span inside the click handler instead. Also, when adding the active class to this, just remove it on any sibling span :
$('span').on('click', function(){
$(this).toggleClass('active').siblings('span').removeClass('active');
});
$('div').on('click', function(e){
if (e.target == this) $('span').removeClass('active');
});
FIDDLE
​

If you want to keep the toggle-off functionality when the span itself has been clicked, then you can use the following. Also, note that you're binding an event handler each time a span is clicked.
http://jsfiddle.net/WP4RH/7/
$("span").click(function() {
$(this).siblings("span").removeClass("active"); // remove from other spans
$(this).toggleClass("active"); // toggle this span
return false;
});
​
$("div").click(function() {
$(this).find("span").removeClass("active"); // remove from all spans
});
