How to toggle only header element not the list

I have this function that expands the <ul> and hides it after it is pressed.But when i press on <li> it will also close or expand. How do I make it to toggle only when the the <h4> is clicked ?
$('.category ul').hide();
$('.sub').click(function() {
$(this).find('ul').slideToggle();
});
<ul class="category text-center">
<li class="sub">
<h4><b>Licenses</b></h4>
<ul class="archive_posts">
<li class="posts">Licence types and users plans</li>
<li class="posts">Adding new licence</li>
<li class="posts">Updating licence</li>
<li class="posts">Removing licence</li>
</ul>
</li>
</ul>
Thanks in advance.

Changes made
► changed $('.sub').click(function() { to $('.sub h4')
► changed $(this).find('ul') to $(this).next()
Working Demo
$('.category ul.archive_posts').hide();
$('.sub h4').click(function() {
$(this).next().slideToggle();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="category text-center">
<li class="sub">
<h4><b>Licenses</b></h4>
<ul class="archive_posts">
<li class="posts">Licence types and users plans
</li>
<li class="posts">Adding new licence
</li>
<li class="posts">Updating licence
</li>
<li class="posts">Removing licence
</li>
</ul>
</li>
</ul>

Change the binding to the h4, then target the next ul.archive_posts for sliding.
$('.category ul').hide();
$('h4').click(function() {
$(this).next('ul.archive_posts').slideToggle();
});
See it working in this JS Fiddle: https://jsfiddle.net/rwvdf8ys/1/
Hope that helps.

The problem is $('this').find('ul').slideToggle();
'this' represents the obj that is cals the function. In this case it is h4. H4 has noe ul, so you cant find it. but you can find ul on $('.sub')
Here is ann example
$('.category ul').hide();
$('h4').click(function() {
$('.sub').find('ul').slideToggle();
});
<ul class="category text-center">
<li class="sub">
<h4 id="foo"><b>Licenses</b></h4>
<ul class="archive_posts">
<li class="posts">Licence types and users plans</li>
<li class="posts">Adding new licence</li>
<li class="posts">Updating licence</li>
<li class="posts">Removing licence</li>
</ul>
</li>
</ul>
js fiddle:
https://jsfiddle.net/8hvc4cfh/

You might use the siblings('ul') selector to find and close the neighbour ul. While $(".sub h4") limits the clickable elements to your h4.
$('.category ul').hide();
$('.sub h4').click(function() {
console.log('test');
$(this).siblings('ul').slideToggle();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="category text-center">
<li class="sub">
<h4><b>Licenses</b></h4>
<ul class="archive_posts">
<li class="posts">Licence types and users plans
</li>
<li class="posts">Adding new licence
</li>
<li class="posts">Updating licence
</li>
<li class="posts">Removing licence
</li>
</ul>
</li>
</ul>

You can try this.
$('li.sub h4').click(function() {
$(this).next().slideToggle();
});

How to get a previous DIV with jQuery

I want to animate an element (.item-i) after I click on another element(.item-1) which is following below. Now I don't know, how to get to this element.
I want only the exact above element animated, not both above, only the first element above.
I made an easy show up in http://jsfiddle.net/Eef4v/1/. The YellowBG is the "animation".
Here is my JS code:
$('.item-1').click(function() {
$(this).closest('.item-i').css( "background", "yellow" );
});
And my HTML Markup:
<ul id="one" class="level-1">
<li class="item-i">I</li>
<li class="item-ii">II
<ul class="level-2">
<li class="item-a">A</li>
<li class="item-b">B
<ul class="level-3">
<li class="item-1">1</li>
<li class="item-2">2</li>
<li class="item-3">3</li>
</ul>
</li>
<li class="item-c">C</li>
</ul>
</li>
<li class="item-iii">III</li>
</ul>
<ul id="Ul1" class="level-1">
<li class="item-i">I</li>
<li class="item-ii">II
<ul class="level-2">
<li class="item-a">A</li>
<li class="item-b">B
<ul class="level-3">
<li class="item-1">1</li>
<li class="item-2">2</li>
<li class="item-3">3</li>
</ul>
</li>
<li class="item-c">C</li>
</ul>
</li>
<li class="item-iii">III</li>
</ul>

Use:
$(this).closest('.item-ii').prev().css( "background", "yellow" );
Working Demo
For Toggling background color:
$(this).closest('.item-ii').prev().toggleClass("highlight");
CSS:
.highlight {background: yellow;}
Demo with ToggleClass

Two ways to get .item-i to highlight.
$(this).parents('.level-1').find('.item-i').css( "background", "yellow" );
but if you have multiple .item-i classes under your .level-1 then they would all turn yellow.
Working Demo
You could also write a find algorithm that goes through each parent of .item-1 and finds the closest item-i
$('.item-1').click(function () {
$(this).parents().each(function(index,elem){
var query = $(elem).find('.item-i');
if(query.length > 0)
{
query.first().css("background-color", "yellow");
return false;
}
});
});

click on li if no leaf node its append in another div

I have one Activity xml file and I am try to get from activity when click on activity there child display. Its look like end of the all click.
<ul id="firstLevelChild">
<ul id="ul">
<li id="4">Activities
<ul class="ul">
<li id="10066">Physical1
<ul class="ul">
<li id="10067">Cricket
<ul class="ul">
<li id="10068">One Day</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</ul>
Now I want that if li have no leaf node then its display in other another div. Something like:
Click on Acitivities there have child node Physical1 and there also child Cricket and there chil One Day now one day have no child when click on one day its display in my <div id="result"></div>

I would add this as a comment, but I don't have enough rep. ChildNodes() isn't a function - since it looks like you're using jQuery, try children() instead.

I think javascript could helpr you there. A part from the fact that you first build your DOM correct ;)
The hasChildNodes() method returns TRUE if the current element node has child nodes, and FALSE otherwise.
http://www.w3schools.com/dom/met_element_haschildnodes.asp

Assuming the markup you provided is how it's going to be always i.e. ul as child for all li. You just check if ul exists inside the current li. See fiddle
HTML
<div id="content">
<ul id="firstLevelChild">
<li>
<ul id="ul">
<li id="4">Activities
<ul class="ul">
<li id="10066">Physical1
<ul class="ul">
<li id="10067">Cricket
<ul class="ul">
<li id="10068">One Day</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
<h2>Result</h2>
<ul id="result"></ul>
JS
$('#content li').each(function (i) {
//for display purpose only
$('#content').append('<span class="list">li(' + i + '):' + $('ul', $(this)).length + '</span>');
//the code you needed
if ($('ul', $(this)).length < 1) {
$(this).on('click', function () {
$('#result').append($(this).parent().html());
});
}
});

jQuery accordion slides up multiple times

I'm making a jquery accordion and I have some issues
My jQuery searches for a ul inside a class and if it has a certain class it slides down, but it slides down as many times as the element ul exists in the whole nav
Here is my jquery code so far:
if($(this).has("ul").length){
$(".menu ul li").on('click',function(e){
$(this).addClass('open').siblings().removeClass('open').children();
$('.menu ul li ul').slideUp();
if($(this).parents().find(".open").length){
$(this).children('ul').slideDown();
}
//$(this).parents().find(".open").children('ul').slideDown();
e.preventDefault();
});
};
this is my html:
<div class="menu">
<a id="jump" href="#"><p>Menu</p><span class="right">▼</span></a>
<nav class="row">
<div class="page_wrapper">
<ul class="niveau_1">
<li class="active">Home</li>
<li>Group
<ul class="sub-menu">
<li>QHSE/Awards</li>
<li>Vacatures/</li>
</ul>
</li>
<li>Nieuws & Media
<ul class="sub-menu">
<li>Van Moer in de media</li>
<li>Nieuwsarchief</li>
</ul>
</li>
<li>Sport & Events
<ul class="sub-menu">
<li>Casual Friday
<ul>
<li>Inschrijving</li>
<li>Foto's</li>
</ul>
</li>
<li>Thursday Lounge</li>
<li>Triatlon</li>
<li>Sponsoring</li>
<li>Beurzen</li>
<li>Kalender</li>
</ul>
</li>
<li>Vestigingen</li>
<li>Contact</li>
</ul>
</div>

just guessing sincei don't have HTML to look too... your problem is here in parents()
Get the ancestors of each element in the current set of matched elements, optionally filtered by a selector.
i think u need parent() here
Get the parent of each element in the current set of matched elements, optionally filtered by a selector.
if($(this).parent().find(".open").length){ //try this
$(this).children('ul').slideDown();
}
note: it would be easy if you provide us with your HTML too

<li><img src="search.png"></li>
</ul>
with the following javascript:
$('.keyboard ul li').click(function() {
var data = $(this).data('letter');
$('.input').append(data);
});
What I want to have happen is when I click on one of the list items, I want the data-letter to insert itself into the input, sorta like an onscreen keyboard. But it isn't working. Can someone help me?
Here is a Fiddle
Update
This works now
My next problem is the uppercase button. When I click the button, the characters turn to uppercase. How would I use the data to inject an uppercase letter into the input?
The final problem is the first row of letters won't inject into the input. How do I fix this?

Try the below
Enable Jquery file instead of mootools in the fiddle
Thanks

Try:
Demo
$('.keyboard ul li').click(function() {
var data = $(this).data('letter');
$('.input').val( $('.input').val()+ data);
});​

All you have to do is remove the margin on the .input element (it's offscreen for me), and enable jquery on the jsfiddle. After that it works fine for me.

Not sure why jquery .data() not work, but you can use below "this.dataset.xxx"
var data = this.dataset.letter;

This is the solution I came up with
keys = $(".keyboard ul li");
keys.on("click", function() {
var let = $(this).text(),
upperlet = let.toUpperCase(),
lowerlet = let;
if (keys.hasClass("uppercase")){
input.append(upperlet);
}else {
input.append(lowerlet);
}
});
Instead of having the data-letter attribute for every single list-item, I got the text using this function, and appended it on click. This now also accounts for the uppercase letters as well.
