JQuery show/hide and collapse if click outside

I've started playing around with JQuery in the last week, and I'm needing some help understanding what I am doing incorrectly. I'm sure this is very simple, but please be patient as I am learning.
End result: When you click "Open Menu" - then the notification menu opens. If you click outside of the ul class ".profiledrop" then the notification menu closes.
// Tab collapser //
$('.notification-tab').click(function(e) {
if ($(e.currentTarget).parent().hasClass('active')) {
$('.notification-group').removeClass('active');
} else {
$('.notification-group').removeClass('active');
$(e.currentTarget).parent().toggleClass('active');
}
});
// Click outside collapser //
$(document).on('click', function(e) {
if ($(e.target).closest(".profiledrop").length === 0) {
$(".profiledrop").hide();
}
});
// Menu Launcher //
$("#launch").click(function() {
$(".profiledrop").show();
});

When you click on menu you need to exclude it from you logic of closing the menu.
So create another if if (e.target.id != "launch") { and wrap your closing menu logic in it. You where opening with one event and closing in same time with another:
$(document).on('click', function(e) {
if (e.target.id != "launch") {
if ($(e.target).closest(".profiledrop").length === 0) {
$(".profiledrop").hide();
}
}
});
I would also suggest to use .toggle(); here so you can open and close menu by clicking the button:
// Menu Launcher //
$("#launch").click(function() {
$(".profiledrop").toggle();
});
EXAMPLE:
// Tab collapser //
$('.notification-tab').click(function(e) {
if ($(e.currentTarget).parent().hasClass('active')) {
$('.notification-group').removeClass('active');
} else {
$('.notification-group').removeClass('active');
$(e.currentTarget).parent().toggleClass('active');
}
});
// Click outside collapser //
$(document).on('click', function(e) {
if (e.target.id != "launch") {
if ($(e.target).closest(".profiledrop").length === 0) {
$(".profiledrop").hide();
}
}
});
// Menu Launcher //
$("#launch").click(function() {
$(".profiledrop").toggle();
});

How to handle event Handler in jQuery 3.4.1

It shows two events at same time:
jQuery Code:
$('[data-trigger="dropdown"]').on('mouseenter', function(){
var submenu=$(this).parent().find('.submenu');
submenu.addClass('active');
}
HTML:
<ul class="profile-menu">
<li>
<a class="profile-menu-trigger" data-trigger="dropdown" href="#">Logged in as User</a>
</li>
<ul class="profile-submenu submenu ">
<li>Login</li>
<li> Logout</li>
<li>Options</li>
<li>Circus</li>
</ul>
</ul>
CSS:
.submenu{
list-style: none;
padding: 0px;
border: 1px solid #aaa;
background: #fff;
margin-top: 30px;
box-shadow: 2px 2px 15px rgba(0, 0, 0, 0.3);
width: 250px;
position: absolute;
right: 20px;
display: none;
}
.submenu.active{ display: block; }
This program should show the menu on top right corner when touch on "User Logged in" but it can't.

Setting height of child divequal to its parent div

I have a div tag in which i have a panel which is accordion. Now my div tag height is dynamic it depends on data and panel is fixed on top of div which will expand with some sub data on click. I want to set the height of my panel equals to its parent div. Note div height is dynamic.
.menuboxcontent {
background-color: deepskyblue;
color: white;
text-align: center;
margin: 10px 0px;

$('.collapse').on('show.bs.collapse', function() {
$(this).parent().find('.glyphicon-menu-down').removeClass('glyphicon-menu-down').addClass('glyphicon-menu-up');
$(this).parent().('.collapse').css('height', boxheight + 'px');
})
$('.collapse').on('hide.bs.collapse', function() {
$(this).parent().find('.glyphicon-menu-up').removeClass('glyphicon-menu-up').addClass('glyphicon-menu-down');
$(this).parent().('.collapse').css('height', (boxheight * 0.1) + 'px');

You could always just set the panel's height to inherit like height: inherit;
This makes your panel inherit the height of it's parent, which is the div with the menuboxcontent class. Your panel would have a height of 100% because you set it's parents height to 100%

Bootstrap 3.0: How to make vertical navbar dropdown not append to only last list item?

So I have a panel layout that I've been throwing together and it has a fancy vertical navbar. I have it aligned correctly and everything and I have successfully been able to get a dropdown menu to appear in a vertical fashion, however, for some reason it is always appending to the last item on list. I can't understand why it is doing this.
I've posted all of my code below, and from previous research on the initial issue of just getting the menu to show up, I believe that my css is correct, so I'm wondering if it may be a javascript issue on the boostrap side, but I have no javascript currently being used with the side menu.

I have a working fiddle to demonstrate what my issue is:
https://jsfiddle.net/ye1q4wfu/4/
All I want it to do is, when I click on the list item that has a dropdown. I want the dropdown to appear next to it.

Just set the top of dropdown to top: auto;
#side-nav .dropdown-menu {
top: auto;
}
https://jsbin.com/fukujazuko/
My internet has some trouble with jsfiddle

If you don't mind using a bit of JQuery, I think this will do the trick:
$('.dropdown-menu').each(function() {
$(this).css('top', $(this).closest('li').css('top'));
});
You will also need to change one line of your CSS:
#side-nav .dropdown-menu{
overflow-x: visible;
width: 100% !important;
//margin: -92px 0 0 100%; /* Removed */
margin: 0 0 0 100%; /* Added */
border-radius: 0;
}
Demo Here

Use the following CSS code that the sub-menu appears in front of the item.
#side-nav .dropdown-menu{
overflow-x: visible;
width: 100% !important;
margin: -290px 0 0 100%;
border-radius: 0;
}

I've added the clearfix class to the li element in which your dropdown menu is. Then, these attributes to dropdown-menu
#side-nav .dropdown-menu {
...
top: auto;
float: right;
}
And added this css rule:
#side-nav .dropdown-toggle {
float: left;
width: 100%;
}
This is the complete snippet with the changes. When showing the code snippet, please, click on "Full page" to see the result.

How to make bottom top layer of website transparent to background slideshow?

Ok so I have a function that slideshow a background in the background of the site . I want the Navigation Links to be transparent and the body to be transparent. Not transparent as in no color , transparent as in you can see the slideshows in the background.
<script>
$(document).ready(function() {
function test() {
var count = $("img").size();
$("#background_images img").each(function(index) {
$(this).hide();
if (!--count)
$(this).delay(10000 * index).fadeIn(3000).delay(10000).fadeOut(1000, function() { test(); });
else
$(this).delay(10000 * index).fadeIn(3000).delay(10000).fadeOut(1000);
});
}
test();
});
-->
</script>

If i understood your question, have you tried rgba, Look Here example:
div {
background: rgba(200, 54, 54, 0.5);
}
the last parameter is the opacity value.
I can't try all your code but look at this test, you can start with this base and do all the other changes you need, its working for the base of your html and with opacity working, you only have to see why in the rest of your code is making it change.
body, html{
background-color:#ffaadd;
width:100%;
height:100%;
}
#background_images
{
width:100%;
height:100%;
border:1px solid green;
background-color:#aaffdd;
position:absolute;
}
#content
{ top:0px;
position:absolute;
border:1px solid red;
}
#navbar{
border:1px solid blue;
position:relative;
background: rgba(200, 54, 54, 0.3);
}
#footer { width: inherit; height: 150px; filter: alpha(opacity=100); -moz-opacity:.40;
opacity:.40;
text-align: center; padding-top: 100% }
/* footer div's "cont" class */
#footer .cont { padding: 5px; }
#footer .footlinks a { color: #fff; text-decoration: none; }
Look how its working HERE
