Editing html+css+js for a drop down nav bar - javascript

I found perfect code for drop down nav bar. But I'm stuck trying to edit it for my needs. Original complete code is situated here: https://github.com/vandoan/Elli/blob/master/dropDownNav.html
And how it looks: http://codepen.io/Xia-lj/pen/KdKOxw
HTML:
<div id="topbar">
<div id="logo">LOGO</div>
<div id="sections_btn_holder">
<button onclick="toggleNavPanel('sections_panel')">Navigator <span id="navarrow">▾</span></button>
</div>
<div id="sections_panel">
<div>
Try adding things like more child div containers, links, buttons, menus, pictures, paragraphs, videos, etc...
</div>
</div>
</div>
CSS:
body {
margin: 0px;
background: #999;
}
div#topbar {
background: -webkit-linear-gradient(#666, #000);
background: linear-gradient(#666, #000);
height: 60px;
}
div#topbar > #logo {
float: left;
width: 140px;
height: 35px;
margin: 8px 0px 0px 30px;
font-size: 36px;
color: #999;
}
div#topbar > #sections_btn_holder {
float: left;
width: 144px;
height: 46px;
padding-top: 16px;
}
div#topbar > #sections_btn_holder > button {
background: #F90;
}
div#topbar > #sections_panel {
position: absolute;
height: 0px;
width: 550px;
background: #000;
top: 60px;
left: 160px;
border-radius: 0px 0px 8px 8px;
overflow: hidden;
z-index: 10000;
transition: height 0.3s linear 0s;
}
div#topbar > #sections_panel > div {
background: #333;
padding: 20px;
height: 238px;
margin: 10px;
color: #FC0;
}
JS:
function toggleNavPanel(x) {
var panel = document.getElementById(x),
navarrow = document.getElementById("navarrow"),
maxH = "300px";
if (panel.style.height == maxH) {
panel.style.height = "0px";
navarrow.innerHTML = "▾";
} else {
panel.style.height = maxH;
navarrow.innerHTML = "▴";
}
}
What I'm trying to get: drop down nav bar like in example, but with three buttons "History", "Philosophy", "Physics". And each of this three sections must contain few books' names, e.g:
History:-
The History of Herodotus.
Titus Livius. The History of Rome.
Ivan Krypiakevych. The Great History of Ukraine.
"Philosophy":-
Works by Plato.
Nicomachean Ethics By Aristotle.
Fables And Aphorisms by Hryhorii Skovoroda.
"Physics":-
Stephen Hawking. A Brief History of Time.
Yakov Perelman. Physics for Entertainment.
I would be grateful to hear from anyone who may be able to help. I'm new in Web-development.

How about something like this CodePen which is same example you provided just a bit modified on the HTML and CSS parts, inside div#sections_panel I've added 3 divs - you mentioned 3 sections in the question - with a .sub_sections class name.
function toggleNavPanel(x) {
var panel = document.getElementById(x),
navarrow = document.getElementById("navarrow"),
maxH = "300px";
if (panel.style.height == maxH) {
panel.style.height = "0px";
navarrow.innerHTML = "▾";
} else {
panel.style.height = maxH;
navarrow.innerHTML = "▴";
}
}

I am making a slider with control and indicators. I am stuck in how to make the indicators linking with the slider itself. I search a lot of keywords, but none of the answers can help me out :(
Trying to make it “Click on indicators > remove nearby active class > add active class to this > slider div match the order of the indicators div list)
$('.carousel-indicators > div').on('click', function(){
$(".carousel-indicators > div").something match the({
'order of the': ($(".slider-inner > div").slider list() + 'order')
});
$(".carousel-indicators > div").closest('div').removeClass('active');
$(this).addClass('active');
});
.slider-inner{
width:200px;
height:200px;
position:relative;
overflow:hidden;
float:left;
padding:3px;
border:#666 solid 1px;
}
.slider-inner > div{
display:none;
width:200px;
height:200px;
}
.slider-inner .active{
display:inline-block;
cursor: pointer;
}
.carousel-indicators{
width: 500px;
float: left;
}
.carousel-indicators > div{
float: left;
width: 30px;
height: 8px;
background-color: #D8D8D8;
margin-right: 30px;
cursor: pointer;
}
.carousel-indicators .active{
background-color: #FF6600;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="slider-outer">
<div class="slider-inner">
<div id="item" class="active" ><p>#1 </p></div>
<div id="item" ><p>#2 </p></div>

</div>
<div class="carousel-indicators">
<div class="active"></div>
<div></div>
<div></div>
</div>

You can add data attributes to the div elements and target in the JS
$('#slider-indicator > li').on('click', function() {
var slideNumber = $(this).data('slide');
var slides = $('#slider > div');
var indicators = $('#slider-indicator > li');
// look for slide with same data-slide as the clicked li
for (var i = 0; i < slides.length; i++) {
if (i === slideNumber) {
$(slides[i]).addClass('active');
$(indicators[i]).addClass('active');
} else {
$(slides[i]).removeClass('active');
$(indicators[i]).removeClass('active');
}
}
});

The problem I am having is that if a category is more than 2 words, it doesn't show the projects with that category. You'll see in the code pen that there is a category called "Testing Testing Testing" and one of the projects has that category assigned to it. But, when you click the Testing Testing Testing category, no projects show up. All of the other categories work however, because they are all only 2 words long.
Any help is greatly appreciated!

Your code break because the .replace(' ', '-') code just replace the first space
if you want to change all space with '-', you should change this code
var category = $(this).text().toLowerCase().replace(' ', '-');
to this
var category = $(this).text().toLowerCase().split(' ').join('-');

when one of menus is chosen and option in select tag, apply button can be worked to be placed to be dynamic html element in Panel below. when a user clicks cancel button, that dynamic html element will be deleted.
As for an issue, when a user chooses one menu, dynamic html element will be redundantly placed to be in panels.
For example,
apply menu 2 > create dynamic html element in panel of menu2 > cancel menu 2 > apply menu other menu (3 or 1) > redundantly create dynamic html elements in previous panel of menu 2 and current panel of menu.
How am I able to completely delete dynamic html element when I click cancel button??

You could use JQuery's empty command, it removes all child elements from the parent element
$("#parent").empty()

When I click a button on the sidebar, and if the current tab is the second tab the navigation tab is going to display the first tab as the second tab lost the focus. How can I keep the second tab in display while clicking a button on the sidebar?
the code is in jsfiddle
https://jsfiddle.net/98okrj0f/9/
The AngularJs scripts works at my local. Can anyone also tell me how to make it work in jsfiddle?

the update jsfiddle.
https://jsfiddle.net/98okrj0f/13/

Since nobody answered you're question I will answer this question like I did the previous ones.
The problem was that you weren't closing you <a> tags with </a>. So the html added extra <a> tags with made the left bar also use a href which is used for your tabs. This way it overrided the open tab.
See the new JSfiddle: https://jsfiddle.net/98okrj0f/19/
Here's the code that was making the error's:
<li ng-repeat = "v2 in V2s">{{v2}}</li>
<li ng-repeat = "v3 in V3s">{{v3}}</li>

When you open chat and click on a name, it calls $scope.openChat(user) which pushes a name to the $scope.chat.openChats array. The ng-repeat is suppoused to watch this array for new values but does NOT update. I tried using $scope.$apply() after I push the value to array but get this error
Error: [$rootScope:inprog] http://errors.angularjs.org/1.3.14/$rootScope/inprog?p0=%24apply
Thanks for any help! Heres my codepen.

The problem is that $mdDialog is creating another (isolated) scope. To use your existing scope you have to call it like this:
$mdDialog.show({
scope: $scope,
controller: 'AppCtrl',
...
For further information check this post.
Also, you have to remove $scope.$apply(): you have to call it only when changes happen outside Angular (in a setTimeout() for example).
Why do I need to link the scope?
Short answer: because $mdDialog documentation says so
The dialog is always given an isolate scope.
Long answer: $mdDialog is a service that basically adds a directive to the page
The dialog's template must have an outer < md-dialog > element
Since directives can be added multiple times in a page, by default they have an isolated scope (see Angular documentation on directive), but you can link your scope to a directive if you need it.
