Drop down menu with clicks

I am creating a drop down menu that shows a submenu when clicked instead of using hover.
When I click it is displayed as it should be but I would like that when I click on another option the previous one is hidden and not kept open as right now.
In advance, thank you very much to the person who takes the trouble to help me, here is the code I'm working with.
$('.parent a').on("click", function(e) {
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
});
* {
margin: 0;
padding: 0;
outline: 0;
box-sizing: border-box;
}
.parent {
display: block;
position: relative;
float: left;
line-height: 30px;
background-color: #4FA0D8;
border-right: #CCC 1px solid;
}
.parent a {
margin: 10px;
color: #FFFFFF;
text-decoration: none;
}
.parent>ul {
position: absolute;
}
.child {
display: none;
}
.child li {
background-color: #E4EFF7;
line-height: 30px;
border-bottom: #CCC 1px solid;
border-right: #CCC 1px solid;
width: 100%;
}
.child li a {
color: #000000;
}
ul {
list-style: none;
margin: 0;
padding: 0px;
min-width: 10em;
}
ul ul ul {
left: 100%;
top: 0;
margin-left: 1px;
}
li:hover {
background-color: #95B4CA;
}
.parent li:hover {
background-color: #F0F0F0;
}
.expand {
font-size: 12px;
float: right;

Move the display logic to ".active" selector in css,
.active {
display: block;
}
then try the following script.
It would check if the click is not inside current menu, if the click is anywhere but current menu, active class will be removed.
var menu = $('.parent a').next('ul')
$(document).mouseup(e => {
if (!menu.is(e.target) // if the target of the click isn't the container...
&& menu.has(e.target).length === 0) // ... nor a descendant of the container
{
menu.removeClass("active");
}
});
$('.parent a').on("click", function (e) {
$(this).next('ul').toggleClass("active");
e.stopPropagation();
e.preventDefault();
});
Here's the full code,
var menu = $('.parent a').next('ul')
$(document).mouseup(e => {
if (!menu.is(e.target) // if the target of the click isn't the container...
&& menu.has(e.target).length === 0) // ... nor a descendant of the container
{
menu.removeClass("active");
}
});
$('.parent a').on("click", function (e) {
$(this).next('ul').toggleClass("active");
e.stopPropagation();
e.preventDefault();
});

using siblings(), you have quickest solution:
parents("li.parent").last() keeps the highest parent li.parent of selected item
.sibling() keeps all others li.parent brothers (of main menu)
.find("ul") keeps all ul children from all li.parent brothers
$('.parent a').on("click", function(e) {
$(this).parents("li.parent").last().siblings().find("ul").hide();
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
});
$('.parent a').on("click", function(e) {
$(this).parents("li.parent").last().siblings().find("ul").hide();
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
});

You could try with
$('.parent a').on("click", function (e) {
$('.parent ul').hide();
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
});

Align the drop-down list content under the parent

Above is the result I want, each drop-down list is under the main title.
For example:
A1, A2, A3, A4 is under A when I click the expand collapse button.
B1, B2, B3, B4 is under B when I click the second expand collapse button.
But now my drop-down list is not aligned accordingly. You can check my code for more details. Hoping that some of you could provide me with some advice.
$(".es_epdtitle").click(function() {
$('.es_expandct').slideToggle().toggleClass('active');
$(this).closest('.mobexpand').toggleClass('collapsed');
});
$(".es_epdtitle1").click(function() {
$('.es_expandct1').slideToggle().toggleClass('active');
$(this).closest('.mobexpand').toggleClass('collapsed');
});
$(".es_epdtitle2").click(function() {
$('.es_expandct2').slideToggle().toggleClass('active');
$(this).closest('.mobexpand').toggleClass('collapsed');
});

Add position:relative to parent to make the drop-down position according to it and move float and width from text_maroon_16.. to the parent mobexpand to maintain the width and the style
See code snippet:
$(".es_epdtitle").click(function() {
$('.es_expandct').slideToggle().toggleClass('active');
$(this).closest('.mobexpand').toggleClass('collapsed');
});
$(".es_epdtitle1").click(function() {
$('.es_expandct1').slideToggle().toggleClass('active');
$(this).closest('.mobexpand').toggleClass('collapsed');
});
$(".es_epdtitle2").click(function() {
$('.es_expandct2').slideToggle().toggleClass('active');
$(this).closest('.mobexpand').toggleClass('collapsed');
});

You could always use flex:
$(".es_epdtitle").click(function() {
$('.es_expandct').slideToggle().toggleClass('active');
$(this).closest('.mobexpand').toggleClass('collapsed');
});
$(".es_epdtitle1").click(function() {
$('.es_expandct1').slideToggle().toggleClass('active');
$(this).closest('.mobexpand').toggleClass('collapsed');
});
$(".es_epdtitle2").click(function() {
$('.es_expandct2').slideToggle().toggleClass('active');
$(this).closest('.mobexpand').toggleClass('collapsed');
});

I build for you a container with tabs and screens,
let me know if that what you looking for.

My Fiddle

I checked your code and looked in the console of the browser; it has one jQuery error like $ is not defined. I think you forget to add jQuery library; that's the way this error occurs. Add jQuery file or you can use jQuery cdn also like this.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
Add this line add before the </body> tag and then check if it works.

highlight active menu item on Page Scroll?

I want to add a active function to the current menu item on page scroll. It’s a single page with different sections. When click on an item, the active state should switch to the current one.
As you scroll down the page, the active menu item changes. How is this done? Would guys give me a answer base on my demo coding? Thanks.
My demo: http://jsfiddle.net/x2skzp1p/1/
var menuContainer = $('header').height();
function scrollToAnchor(anchorName) {

You can use onscroll event to set active div and an active class to set it:
$(function () {
$("body").onscroll(function () {
$("#navmenu li").removeClass("active");
if ($("body").scrollTop() > $("#section5").offset().top)
$("#navmenu li").eq(4).addClass("active");
else if ($("body").scrollTop() > $("#section4").offset().top)
$("#navmenu li").eq(3).addClass("active");
else if ($("body").scrollTop() > $("#section3").offset().top)
$("#navmenu li").eq(2).addClass("active");
else if ($("body").scrollTop() > $("#section2").offset().top)
$("#navmenu li").eq(1).addClass("active");
else
$("#navmenu li").eq(0).addClass("active");
});
});

/* nadeem css */
.newstyles{ font: 20px/18px arial;color: #0B0B0C;margin: 5px 0px 20px 5px;}
.newstyles li{ height: 32px;font: bold 12px/32px arial;color: #0B0B0C;}
.newstyline{clear: both;height: 1px;background-color: #E6E6E6;width: 100%;margin: 1px 0px 3px 0px;}
}
here is the js
$(document).ready(function() {
setTimeout(function() {
// Slide
$('#menu1 > li > a.expanded + ul').slideToggle('medium');
$('#menu1 > li > a').click(function() {
$(this).toggleClass('expanded').toggleClass('collapsed').parent().find('> ul').slideToggle('medium');
});
$('#example1 .expand_all').click(function() {
$('#menu1 > li > a.collapsed').addClass('expanded').removeClass('collapsed').parent().find('> ul').slideDown('medium');
});
$('#example1 .collapse_all').click(function() {
$('#menu1 > li > a.expanded').addClass('collapsed').removeClass('expanded').parent().find('> ul').slideUp('medium');
});
}, 250);
});
and here is the html
<div id="example1">
<div><a class="expand_all"><img src="images/close.jpg" class="img-swap" /></a><a class="collapse_all"><img src="images/open.jpg" alt="" /></a></div>
<ul id="menu1" class="example_menu">
<li><a class="expanded">Section A</a>
<ul class="newstyles">
<li>Link A-A</li>
<div class="newstyline"> </div>
<li>Link A-B</li>
<div class="newstyline"> </div>
<li>Link A-C</li>
<div class="newstyline"> </div>
<li>Link A-D</li>
</ul>
</li>
<li><a class="expanded">Section B</a>
<ul class="newstyles">
<li>Link A-A</li>
<div class="newstyline"> </div>
<li>Link A-B</li>
<div class="newstyline"> </div>
<li>Link A-C</li>
<div class="newstyline"> </div>
<li>Link A-D</li>
</ul>
</li>
<li><a class="expanded">Section C</a>
<ul class="newstyles">
<li>Link A-A</li>
<div class="newstyline"> </div>
<li>Link A-B</li>
<div class="newstyline"> </div>
<li>Link A-C</li>
<div class="newstyline"> </div>
<li>Link A-D</li>
</ul>
</li>
</ul>
</div>

Guessing it is the two images in the top, you could do this:
<div>
<a class="expand_all" style="display: none;" onclick="$('.expand_all').hide();$('.collapse_all').show()">
<img class="img-swap" src="images/toggle-buttons_01.png">
</a>
<a class="collapse_all" onclick="$('.expand_all').show();$('.collapse_all').hide()" style="display: inline;">
<img alt="" src="images/toggle-buttons_02.png">
</a>
</div>
Simply hiding the irrelevant one....not really swapping images though.
