I want to color the first links : "category 1" and "category 2".
I try but only the first link is coloring red.
Thanks for your help !


You can use immediate child selector > to target immediate anchor elements both using CSS and jquery.
Using CSS:
.item_has_children > a{color:red;}
Working Demo using CSS:
.item_has_children>a {
color: red
}
<ul>
<li class="item_has_children">
Category 1
<ul class="submenu">
<li class="menu_item">
Hello
</li>
<li class="menu_item">
Hello
</li>
</ul>
</li>
<li class="item_has_children">
Category 2
<ul class="submenu">
<li class="menu_item">
Hello
</li>
<li class="menu_item">
Hello
</li>
</ul>
</li>
</ul>
Using Jquery:
$('.item_has_children > a').css("color","red");
Working Demo using Jquery:
$('.item_has_children > a').css("color","red")
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
<li class="item_has_children">
Category 1
<ul class="submenu">
<li class="menu_item">
Hello
</li>
<li class="menu_item">
Hello
</li>
</ul>
</li>
<li class="item_has_children">
Category 2
<ul class="submenu">
<li class="menu_item">
Hello
</li>
<li class="menu_item">
Hello
</li>
</ul>
</li>
</ul>


No need to use javascript for this, you can use CSS.(Better Performance and User Experience)
.item_has_children > a {
color: red;
}
> here will select direct children of .item_has_children element.
Demo:
.item_has_children>a {
color: red;
}
<ul>
<li class="item_has_children"> Category 1
<ul class="submenu">
<li class="menu_item"> Hello
</li>
<li class="menu_item"> Hello
</li>
</ul>
</li>
<li class="item_has_children"> Category 2
<ul class="submenu">
<li class="menu_item"> Hello
</li>
<li class="menu_item"> Hello
</li>
</ul>
</li>
</ul>


operator > is used for select immediate started DOM element of selector.
$("li.item_has_children > a").css("color","red");

My sub menu is still not working properly (jQuery)

I'm creating a sub menu using jquery. I have made the code as below. But there is still something that is not working properly. What I want is, when the start, the menu is closed. Currently, all menus are open. How do I do it, can anyone help me?
$('.list-menu > li').click(function () {
var child = $(this).children('ul');
if(child.length===0){
$(this).children().addClass("active");
return;
}
$('.list-menu ul').not(child).slideUp('normal');
child.slideDown('normal');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul class="list-menu">
<li class="menu-1">
Getting Started
<ul class="submenu">
<li id="sub-1">Child 1
</li>
<li id="sub-2">Child 2
</li>
</ul>
</li>
<li class="menu-2">
Controlling How Data is Indexed
<ul class="submenu">
<li id="sub-3">Child 1
</li>
<li id="sub-4">Child 2
</li>
</ul>
</li>
<li class="menu-3">

<li id="sub-6">Child 2
</li>
</ul>
</li>
<li>
<a href="#">

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

You can set the child ul elements to display: none on page load using CSS:
ul > li > ul { display: none; }
$('.list-menu > li').click(function() {
var child = $(this).children('ul');
$(this).children().addClass("active");
$('.list-menu ul').not(child).slideUp('normal');
child.slideToggle('normal');
});
ul > li > ul { display: none; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul class="list-menu">
<li class="menu-1">
Getting Started
<ul class="submenu">
<li id="sub-1">Child 1
</li>
<li id="sub-2">Child 2
</li>
</ul>
</li>
<li class="menu-2">

<ul class="submenu">
<li id="sub-3">Child 1

Nested collapse

I'm trying to collapse a nested menu with jQuery. I read this answer and, to me, it appears to be similar to my solution. The problem is that mine doesn't work.
What I think I'm saying with my JavaScript code is: "hey, when a user clicks on a li that is the parent of a ul.submenu, get its ul.submenu children and attach the slideToggle only to it". But, as you can see from the snippet, it closes also the parent ul.submenu and I can't understand why.
$(document).ready(function () {
$('.submenu').hide();
$('.submenu').parent('li').click(function () {
$(this).children('ul.submenu').slideToggle("slow");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<nav>
<ul class="menu">
<li>Home</li>
<li>Blog
<ul class="submenu">
<li>
Author
<ul class="submenu">
<li>New</li>
<li>Handle</li>
</ul>
</li>
<li>
<span>Category</span>
<ul class="submenu">
<li>New</li>
<li>Handle</li>
</ul>
</li>
<li>
<span>Tag</span>
<ul class="submenu">
<li>New</li>
<li>Handle</li>
</ul>
</li>
<li>
<span>Post</span>
<ul class="submenu">
<li>New</li>
<li>Handle</li>
</ul>
</li>
</ul>
</li>
<li>Photo</li>
<li>Settings</li>
</ul>
</nav>

You want to stop the click event from bubbling up the DOM and triggering the click handler on the parent. Use .stopPropagation() for that:
$(document).ready(function() {
$('.submenu').hide();
$('.submenu').parent('li').click(function(e) {
e.stopPropagation()
$(this).children('ul.submenu').slideToggle("slow");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<nav>
<ul class="menu">
<li>Home</li>
<li>Blog
<ul class="submenu">
<li>
Author
<ul class="submenu">
<li>New</li>
<li>Handle</li>
</ul>
</li>
<li>
<span>Category</span>
<ul class="submenu">
<li>New</li>
<li>Handle</li>
</ul>
</li>
<li>
<span>Tag</span>
<ul class="submenu">
<li>New</li>
<li>Handle</li>
</ul>
</li>
<li>
<span>Post</span>
<ul class="submenu">
<li>New</li>
<li>Handle</li>
</ul>
</li>
</ul>
</li>
<li>Photo</li>
<li>Settings</li>
</ul>

how to hide child elements child elements in jQuery

I have a menu populating from MySQL table and PHP up to some nested sub levels.
my menu like this:
A
B
C
If click on A first time it is showing all the child elements and again I click child elements of A it displaying child elements also fine.
But the problem is when I click on the B after open all the levels items of A it shows B sub elements fine. But again if I click A it showing all the elements except child child elements also.
I used jQuery for this.
So I want to bring back to the original state? ( only expand the top child elements, not the sub child elements ),
how to do that?
//this is my jquery code for elements clickable in menu.
$(document).ready(function() {
$(".lichild").parent().hide();
$(".limain").click(function() {
$(this).children('ul').show();
$(this).siblings(".limain").children('ul').hide();
});
$(".lichild").click(function() {
$(this).children('ul').show();
$(this).siblings().children('ul').hide()
});
});
<!-- This is the html I am generating using a PHP function -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li class="limain">A
<ul>
<li class="lichild">A1
<ul>
<li class="lichild">a2</li>
<li class="lichild">a1
<ul>
<li class="lichild">aaaaaa</li>
<li class="lichild">abbbbbb</li>
</ul>
</li>
</ul>
</li>
<li class="lichild">A2</li>
<li class="lichild">A3</li>
<li class="lichild">A4</li>
<li class="lichild">A5</li>
</ul>
<li class="limain">B
<ul>
<li class="lichild">B1</li>
<li class="lichild">B2</li>

Use find inside siblings and hide it.
$(".lichild").parent().hide();
$(".limain").click(function() {
$(this).children('ul').show();
$(this).siblings(".limain").find('ul').hide(); // Change in this line
});
$(".lichild").click(function() {
$(this).children('ul').show();
$(this).siblings().children('ul').hide()
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<ul>
<li class="limain">
A
<ul>
<li class="lichild">

<ul>
<li class="lichild">D1</li>

Here is an example using your code. In the HTML I added a class tmenu-menu to your last menu item, like this:
Tmenu <b class="caret"></b>
<ul class="dropdown-menu dropdown-menu-large row tmenu-menu">
Then added this code in the CSS
#media (min-width: 1200px) {
.tmenu-menu {
right: 0;
left: inherit;
}
}
Now when you view your site and the width of your browser is 1200px or bigger you will see the large menu sit on the right hand side of your screen. Then when you shrink down the menu once below 1200px the menu will go back to the left side. One SO answer provides the various break points sizes but these are also available on the bootstrap website.
You will have to add your own custom classes and position the menus based on where you want them for each width size. I have updated your js.fiddle with my example code (I also left in the different media sizes that BS uses). This code isn't complete but should help you get pointed in the right direction. Hope that helps.

Combine Navigation UL jQuery Function

I am trying to write a function that will combine two children ul#level_2and append them to their parent li#level_1 within a dropdown #navigation.
I currently have the following which does the job, but it means I have to manually target each category. I'm sure there is a far shorter way to produce the same results with very little code.
$('li#furniture ul.level_2').children('li').appendTo('li#furniture ul.level_2:first');
$('li#furniture ul.level_2').children('li').not(':first').remove();
Here is a shortened version of my current html structure & below is the desired result:
