Is there any way to remove all the divs only on load, in order to display barcoffeshop

Select the list item with data-filter as barcoffeeshop and call .focus() on it using javaScript when the page loads.

In the previous image you can see a scorm with a list of pages on the left and a counter down at the center.

$(".ViewerPagination__page").text(summa+1);
if (summa === $("li.liItem").length) {

$('a.nav_delante').off();
}
});
$('a.nav_atras').on( "click", function(){

If you click on the item of the list, it works fine, but i have problems with the next and back buttons, it does not work until you select an item from the list and sometimes they work badly since they start counting -1, -2 when you press the back button and they go past the number of items in the list with the forward button.
Can someone help me to solve this problem with a best code? thanks.

i just uploaded the scorm, you can see it online following the next link, you only have to loging, I know, it is boring, but it is the only way that I can show you this, so I am waiting for your help.

How to get the "id" of moving sortable UIKit 3 element using JavaScript?

I want to know or print which card that is being dragged let's say upon drop and show it in the UIKit notification. I checked the console.log but nothing happens. From the documentation, it is only possible to get even on moving but not to get the value of the element that is being dragged. My code is below.

JS:
UIkit.util.on('#sortable', 'moved', function () {
//console.log();
UIkit.notification('Card has been moved.', 'success');
});
Thanks!

If you modify:
UIkit.util.on('#sortable', 'moved', function () {
//console.log();
UIkit.notification('Card has been moved.', 'success');
});
To be:
UIkit.util.on('#sortable', 'moved', function (item) {
console.log(item.detail[1].id)
UIkit.notification(`Card is ${item.detail[1].id}`, 'success');
});
It will display the elements id in the notification. You can go higher up in the "item" object in order to get more information on the dropped element.
Also, I'm using a template literal here to put the id in the notification. That's not supported via IE 11 so you might want to do something more traditional if you care about that.
For reference, you can see the data captured when moving elements via developer console here:

Change display and icon when click on <a> element

I want to know how to change display style and element class when I click on element:
and also I'm loading " jquery.min.js version: 2.1.4 " and " bootstrap.min.js "
Before click on element:
<ul class"nav navbar-nav" >
<li class="nav-item search">
<!-- this a element -->
<a class="nav-link search-toggle" id="nav-link-search" href="#" title="Search Posts">
<i class="fa fa-fw fa-search"></i>
<span class="sr-only">
Search
</span>
</a>
</li>
</ul>
</div>
<progress class="nav-progressbar" max="100" title="How much of the page you have seen so far. Hold and drag to change page position." value="0"></progress>
</nav>
<div class="search-area">
<div class="container">
<div class="search-area-input">
<input placeholder="Search articles" type="text">
</div>
<div class="search-area-results index">
<ol class="article-index-list"></ol>
</div>
</div>
</div>
And after click on element:
<nav class="nav navbar-nav">
<li class="nav-item search">
<!-- this a element -->
<a class="nav-link search-toggle" href="#" title="Search articles">
<i class="fa fa-fw fa-times" title="Close search"></i>
<span class="sr-only">
Search
</span>
</a>
</li>
</ul>
</div>
<progress class="nav-progressbar" max="100" title="How much of the page you have seen so far. Hold and drag to change page position." value="0"></progress>
</nav>
<div class="search-area" style="display: block;">
<div class="container">
<div class="search-area-input">
<input placeholder="Search articles" type="text">
</div>
<div class="search-area-results index">
<ol class="article-index-list"></ol>
</div>
</div>
</div>

$("a").click(function(){
var i =$(this);
i.removeAttr('title');
i.attr('title','Search articles');
i.removeAttr('id');
var j = $('i.fa-search');
j.removeAttr('class');
j.attr('class','fa fa-fw fa-times');
j.attr('title','Close search');
$('.search-area').css('display',"block");
});
if u want to (display:none) again
$("a").click(function(){
var i =$(this);
i.removeAttr('title');
i.attr('title','Search Posts');
i.attr('id','nav-link-search');
var j = $('i.fa-times');
j.removeAttr('class');
j.attr('class','fa fa-fw fa-search');
j.removeAttr('title');
$('.search-area').css('display',"none");
});

$(document).on('click', ".search-toggle", function(e) {
e.preventDefault();
$(".search-area").show();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<nav>
<div><ul class="nav navbar-nav">
<li class="nav-item search">
<!-- this a element -->
<a class="nav-link search-toggle" id="nav-link-search" href="#" title="Search Posts">
<i class="fa fa-fw fa-search"></i>
<span class="sr-only">
Search
</span>
</a>
</li>
</ul>
</div>
<progress class="nav-progressbar" max="100" title="How much of the page you have seen so far. Hold and drag to change page position." value="0"></progress>
</nav>
<div class="search-area" style="display: none;">
<div class="container">
<div class="search-area-input">
<input placeholder="Search articles" type="text">
</div>
<div class="search-area-results index">
<ol class="article-index-list"></ol>
</div>
</div>
</div>

The code below will add the display: block to the element "search-area". This is given you have a clicking element with the class "element".
$(".element").click(function(){
$(".search-area").css( "display", "block" );
});

To change an element when you click on a link, the general concept is
$('a').on('click',function(e) {
e.preventDefault(); // don't follow the link
$('.search-area').addClass('something').removeClass('somethngElse'); // change .search-area
$('i.fa').addClass('something').removeClass('somethingElse').attr('title','foobar'); // change your i element
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class"nav navbar-nav" >
<li class="nav-item search">
<!-- this a element -->
<a class="nav-link search-toggle" id="nav-link-search" href="#" title="Search Posts">
<i class="fa fa-fw fa-search"></i>
<span class="sr-only">
Search
</span>
</a>
</li>
</ul>
</div>
<progress class="nav-progressbar" max="100" title="How much of the page you have seen so far. Hold and drag to change page position." value="0"></progress>
</nav>
<div class="search-area">
<div class="container">
<div class="search-area-input">
<input placeholder="Search articles" type="text">
</div>
<div class="search-area-results index">
<ol class="article-index-list"></ol>
</div>
</div>
</div>

A couple possible issues in the code provided:
Your inner ng-repeat is on the wrong element. It should be on the <li> element right above it. When nesting lists in bootstrap, you never repeat <ul> without wrapping each in atleast an <li> (usually an <a> too, which holds the dropdown text).
To achieve nested tables (a list of lectures within each section), you want the lectures variable to be on each section. This would make your inner ng-repeat something like ="lecture in section.lectures".
Here is a working JSBin where I made the changes I listed above. I omitted a lot of your HTML, because it was broken without the rest of your controller, but I left in enough to show how to get the nested repeats working.

Since you want to show the lecture conditionally, based on the above section_id, you can use ng-if for the desired result.
E.g.
<div class="section" ng-repeat="sec in sections">
<span>Section Id: <i>{{sec.section_id}}</i></span>
<span>Section Name: <i>{{sec.section_name}}</i></span>
<div class="lecture" ng-repeat="lec in lectures" ng-if="lec.section_id==sec.section_id"> <!--nested ng-repeat for lectures-->
<span>Lecture Id: <i>{{lec.lecture_id}}</i></span>
<span>Lecture Name: {{lec.lecture_name}}</span>
</div>
</div>
In JS my data is in the following format:
$scope.sections=[
{section_id:1,section_name:"php"},
{section_id:2,section_name:"java"}
];
$scope.lectures = [
{section_id:1,lecture_id:2,lecture_name:"basics"},
{section_id:2,lecture_id:1,lecture_name:"loops"}
];
I've prepared a JSBIN so you can see what's going on.
