Bold submenu items in sidebar menu

I followed the explanation below to create what I needed, but there is an additional requirement i am trying to fulfill.
highlight the navigation menu for the current page
My submenu items are anchor links on the same page as the main menu item. Example:
$(function() {
var url = window.location.href;
$(".imagingmenu a").each(function() {
if (url == (this.href)) {
$(this).closest("li").addClass("active");
$(this).closest("li").parent().parent().addClass("active");
}
});
});
.imagingmenu ul li.active a, .imagingmenu ul li a:hover {
font-weight:bold;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="imagingmenu">
<ul>
<li>Menu item 1
<li>Menu item 2
<ul>
<li>Submenu Item 1</li>
<li>Submenu Item 2</li>
<li>Submenu Item 3</li>
</ul>
</li>
</ul>
</div>
You can see the bolding works when you hover over the submenu items, but when they are clicked and active, I want just that submenu item to be bolded and the other not to be. However, when any of the submenu items are active, all of them in the list are bolded. How can I achieve what I'm looking for?
Thanks.

This is your problem: $(this).closest("li").parent().parent().addClass("active");
When you click on a "Submenu Item" such as "Submenu Item 2" your code adds the active class to that item, but it also adds the active class to the parent-of-the-parent of the <li> that was clicked.
The parent of the <li> is the enclosing <ul> and the parent of that is the <li>Menu item 2 so what you end up with is this (notice the places where the active class was added)
<ul>
<li>Menu item 1
<li class="active">Menu item 2
<ul>
<li>Submenu Item 1</li>
<li class="active">Submenu Item 2</li>
<li>Submenu Item 3</li>
</ul>
</li>
</ul>
The <li> for "Menu item 2" gets the active class so it is bold according to the CSS rule.imagingmenu ul li.active a
That is, the whole <li> including all its children — the inner <ul> and all its <li>s are bold.
Try commenting out that line as below (I also added some console.log()s so I could see what it was doing)
$(function() {
var url = window.location.href;
$(".imagingmenu a").each(function() {
console.log(`this.href=${this.href} compare to url ${url}`);
if (url == (this.href)) {
console.log('this is', $(this));
console.log('this.closest(li) is', $(this).closest('li'));
$(this).closest("li").addClass("active");
//$(this).closest("li").parent().parent().addClass("active");
}
});
});
You may also have a problem because adding the hash # target doesn't reload the page so it doesn't re-run your function.
In reality I, personally, would handle this completely differently — I'd add a click handler to the list items; the handler receives an event parameter, and you can use the event.target to add the "active" class to the one list item that was clicked.

jQuery Sortable - moving elements between list with Double-Click

I would like to add a functionality to the original jQuery Sortable Connect List example at: http://jqueryui.com/sortable/#connect-lists
Since my second list (#sortable2) is kind of large... I would like to be able to scroll the page down and once I found the item that I need to select/move... just Double.Click on it in order to move it to the other list.
I need to move the items (li) from #sortable2 to #sortable1 as well as from #sortable1 to #sortable2. The idea is just to Double-Click and not Dragging.
THANKS!

Your html
<ul id="sortable1" class="sortable_list connectedSortable">
<li class="ui-state-default">sortable1 Item 1</li>
<li class="ui-state-default">sortable1 Item 2</li>
</ul>
<ul id="sortable2" class="sortable_list connectedSortable">
<li class="ui-state-default">sortable2 Item 1</li>
<li class="ui-state-default">sortable2 Item 2</li>
</ul>
Only from id = sortable2 you will have the items appended to sortable1 with li.class = ui-state-default. This adds one li item at a time from sortable2 to sortable1 .
script
//attach on load
$(function() {
$("#sortable2 .ui-state-default").dblclick(function(){
$("#sortable1").append(this);
});
});

$(function() {
$("ul li").dblclick(function(){
var parentID = $(this).parent().attr('id'); //sortable1 or sortable2
if(parentID.match(/^(sortable1)$/g))
$("#sortable2").append(this);
else if(parentID.match(/^(sortable2)$/g))
$("#sortable1").append(this);
});
});

Javascript onClick for mobile devices

I am working on a submenu for a nav that I need to be accessible for mobile and tablet devices. I am aware that using onClick="return true" will do the trick, however, I also need my list item to close when the user clicks on the list item. Basically I need it to toggle the submenu. If I add this simple line of Javascript, it will work but the submenu will always remain open. How can I get it to close/toggle the submenu?
HTML:
<nav>
<ul>
<li class="active">Menu 1</li>
<li>Menu 2</li>
<li>Menu 3</li>
<li class="bg"><a class="dropdown" href="#">Menu 4</a>
<ul>
<li>Sub 1</li>
<li>Sub 2</li>
</ul>
</li>
</ul>
</nav>
Javascript:
$('nav li.bg').on('click', function(){
return true;
}

You can use touchstart event which fires on mobile browsers.
$('nav li.bg').on('click touchstart', function(){
return true;
});
More touch based events

A virtual method for p click:
$('p').on("touchstart",p_touch_start);
$('p').on("touchmove",p_touch_move);
$('p').on("touchend",p_touch_end);
function p_touch_start(){
p_touch_move.cancel_click = false;
}
function p_touch_end(){
if(p_touch_move.cancel_click) return;
p_touch_move.cancel_click = true;//avoid somehow repeat call
//trigger onclick()
}
function p_touch_move(){
//user is drag page, not click
p_touch_move.cancel_click = true;
}

I figured out the issue after some researching and help. Here is what was updated in my code to trigger this on mobile devices correctly after some updating of my CSS as well:
function is_touch_device() {
return (('ontouchstart' in window) || (navigator.MaxTouchPoints > 0) || (navigator.msMaxTouchPoints > 0));
}
if(is_touch_device()) {
$('.bg').on('click', function(){
$(this).toggleClass('activate');
$(this).find('ul').slideToggle();
return false;
});
}

Add css class to parent li and sub li

I have a submenu like below:
<ul id="main-menu" class="" style="">
<li class="root-level has-sub">
Menu 1
<ul>
<li>Sub-menu 1</li>
<li>Sub-menu 2</li>
</ul>
</li>
<li>Menu 2</li>
<li class="root-level has-sub"> <!-- here -->
Menu 3
<ul>
<li class="root-level has-sub"> <!-- add class 'opened' here and -->
Sub-menu 3
<ul>
<li>Sub-sub-Menu 1</li> <!-- this -->
<li>Sub-sub-Menu 2</li> <!-- when user click this or -->
</ul>
</li>
</ul>
</li>
What I would like to have is, when I click to the child, it will add 'opened' class to parent and highlight the clicked element. My code only success on Menu 1 and failed on Menu 3.
Notice that, in Menu 3, there are 2 parents for Sub-sub-Menu 1 and Sub-sub-Menu 2. So my question is, if i click on Sub-sub-Menu 1 or Sub-sub-Menu 2 it will highlight and add 'opened' class to 2 parents li above.
Note: I try to implement unlimited level of menu
Here is my full code Fiddle

I think you should use a different selector(for the click event). Look for all li>a pairs, corresponding to the submenu items, inside your #main-menu list
$('#main-menu li>a').click(function (e) {
e.preventDefault();
$('.active').removeClass('active');
$('.opened').removeClass('opened');
$(this).parent('li').addClass('active').parents('.root-level').addClass('opened');
//------------------------------------------------------^-----------------------------
// selects all parents with the 'root-level' class
});
Modifying the css to:
#main-menu .active {
background-color:#df0000;
color:#fff;
}
DEMO

you simply use the not: attribute in your closest() method to exclude all classes root-level
$(function () {
$('ul#main-menu li ul li').click(function (e) {
e.preventDefault();
//we search for the first ancestor of this which is a li
$(this).closest('li:not(".root-level")').addClass('active').siblings().removeClass('active');
$('.active:first').closest('ul').addClass('opened');
});
});
check the link http://jsfiddle.net/GEj4z/11/

If I understood correctly what was desired was being able to produce a menu like behavior and it is because of that I would like to present an alternate solution:
Sample Fiddle
$('#main-menu').on('click','li:not(.root-level)',function(e){
$('.parent').removeClass('parent');
$('.selected').removeClass('selected');
$(this).parents('li.root-level').children('a').addClass('parent');
$(this).children('a').addClass('selected');
});
In this solution the parent menus are highlighted and the clicked item is marked as selected again I wanted to share my POV of this problem. I hope it helps.

Inside your click event use $(this).parents('li') to get the top level parent li of the clicked element. I hope this helps.

I found the solution! my jquery is:
$(function () {
$('ul#main-menu li ul li').click(function (e) {
e.preventDefault();
$(this).closest('li:not(".root-level")').addClass('active').siblings().removeClass('active');
$(this).parents('li').addClass('opened');
$(this).closest('li:has(".root-level")').removeClass('active');
});
});
Here is my full code JSFiddle

How do i .removeClass('active') for just one of my <li> elements with jQuery?

I am having some issues figure out how i can just remove a class ="active" from a just one of my lists.
I have a navigation bar:
<div class="container">
<ul class="nav">
<li class="active">Home</li>
<li>About</li>
<li>Contact</li>
</ul>
</div>
I also have a menu within Home:
<div class="container_2">
<ul>
<li class="left-main-list active">Subject 1</li>
<ul class="list-in-list">
<li>Sub subject 1</li>
<li>Sub subject 2</li>
</ul>
<li class="left-main-list>Subject 2</li>
<li class="left-main-list>Subject 3</li>
</ul>
</div>
While i browse my menu on the home page, i want to change the the active list items class to active when clicked, so i now have this jQuery code:
$(document).ready(function() {
$('li').click(function() {
$('li').removeClass('active');
$(this).addClass('active');
});
});
This works for my menu, the class change to the current one, but it also delete my navigation bars class, which i don't want. :)
I have tried something like:
$(document).ready(function() {
$('.left-main-list').click(function() {
$('.left-main-list li').removeClass('active');
$(this).addClass('active');
});
});
I've tried '.left-main-list li' & 'li.left-main-list' without any success.
Greatful for answer to this question, and i hope my question (this time) is more accurate than my previous ones. :)

ps: Can a sub subject AND a main subject be active at the same time, and that sub subject's class of active, be removed if you for example click another sub subject, but the main item still have it's class of active?

While i browse my menu on the home page, i want to change the the
active list items class to active when clicked
You could just target the lis within the relevant div, similar to this:
$(document).ready(function() {
var $listItems = $('div.container_2 li');
$listItems.click(function() {
$listItems.removeClass('active');
$(this).addClass('active');
});
});
DEMO - target lis within .container_2 only
Can a sub subject AND a main subject be active at the same time, and
that sub subject's class of active, be removed if you for example
click another sub subject, but the main item still have it's class of
active?
Still targeting the container you could use jQuery's parent(), similar to this:
$(document).ready(function () {
$('div.container_2 li').click(function () {
var $this = $(this);
var $children = $this.parent().find('li');
$children.removeClass('active');
$this.addClass('active');
});
});
DEMO - Using parent() to allow active menu and sub-menu but not when main menu changes
I looked at the possibility of making this more dynamic to add activation of items going up the chain when switching between sub menus located within different main menu elements.
Fixing the HTML of the nested uls whereby your nested uls are inside lis instead of just inside the upper ul you can do a fully dynamic implementation.
Assume your HTML like this:
<div class="container">
<ul class="nav">
<li class="active">Home</li>
<li>About</li>
<li>Contact</li>
</ul>
</div>
<div class="container_2">
<ul>
<li class="left-main-list active">Subject 1
</li>
<li>
<ul class="list-in-list">
<li>Sub subject 1
</li>
<li>Sub subject 2
</li>
<li>
<ul class="list-in-list">
<li>Sub subject 1
</li>
<li>Sub subject 2
</li>
</ul>
</li>
</ul>
</li>
<li class="left-main-list">Subject 2
</li>
<li class="left-main-list">Subject 3
</li>
</ul>
</div>
Now, using the following script, you can also make parents of any sub menu items active when changing from a sub menu to another which is within another main menu item, similar to this:
$(document).ready(function () {
$('div.container_2 li>a').click(function () {
var $this = $(this);
var $relatedElements = $this.parents('ul').find('li');
if($this.hasClass('active')){
return;
}
$relatedElements.removeClass('active');
$this.parent('li').addClass('active');
var $parents = $this.parents('li');
$parents.each(function(){
$(this).not($this.parent()).prev().addClass('active');
});
});
});
DEMO - Chain-like activation
I think this should have all possible examples to get you started from here.
Hope this helps.

Try this:
$("li").click(function() {
$(this.parentNode).children("li").removeClass("active");
$(this).addClass("active");
});
This will affect only the siblings of the element you click on.

$('.left-main-list').click(function() {
$('.left-main-list').removeClass('active');
$(this).addClass('active');
});

I think what you're looking for is this:
$(document).ready(function() {
$('li').click(function() {
$('li.left-main-list').removeClass('active');
$(this).addClass('active');
});
});

How about
$('li').on ('click', function (){
$(this).addClass ('active').siblings ('li').removeClass ('active');
})
