Open one drop-down, close another with JavaScript

I am using this script to open a drop down menu and then close it when anything else but the trigger is clicked. Now I am trying to add a second drop down to another area on the page and repeat the script but it is breaking.
For instance, I click button A (Gravatar), and drop down A opens.
However when I add the second script and click button B (category) to open drop down B, down down A stays open.
Also adding the second script breaks the drop down close function of the first script.
Here is the script:
<script>
function openAccount(event) {
event.stopPropagation();
document.getElementById("gravatar").classList.toggle("open");
}
window.onclick = function(event) {
document.getElementById("gravatar").classList.remove("open");
}
</script>
<script>
function openCategory(event) {
event.stopPropagation();
document.getElementById("category").classList.toggle("open");
}
window.onclick = function(event) {
document.getElementById("gravatar").classList.remove("open");
}
</script>
<li class="gravatar">
<a href="#" class="dropbtn" onclick="openAccount(event)">
<img src="<?php echo $gravatar; ?>" alt="" />
<span class="fa fa-icon fa-caret-down"></span>
</a>
<ul class="dropdown" id="gravatar">
<li class="header">
<?php echo $user['email']; ?>
</li>
</ul>
</li>
<div class="category">
Properties<span class="fa fa-icon fa-caret-down"></span>
<div id="category">Test</div>
</div>
Goals:
Multiple drop down menus on different parts of the page.
On click opens drop down.
Click on anywhere else on the page closes the drop down.
On click also closes any previously opened menu.

I'd do something really simple like putting a data* attribute on the element that's clicked on that contains the ID of the element to show or hide, e.g.
// Toggle hidden class on/off
function toggleVis(event) {
// Stop click on element bubbling (to body)
event.stopPropagation();
// Get target element
var el = document.getElementById(this.dataset.id);
// If non-target elements are visible, hide them
hideAll(el);
// Toggle target
el.classList.toggle('hidden');
}
// Hide all, excluding passed element
function hideAll(el) {
Array.from(document.querySelectorAll('ul:not(.hidden)')).forEach(function(node){
if (el != node) node.classList.add('hidden');
});
}
// Attach listeners
window.onload = function() {
// Add to linkLike spans
Array.from(document.querySelectorAll('.linkLike')).forEach(function(node) {
node.addEventListener('click', toggleVis, false);
});
// Add hideAll listener to wndow
window.addEventListener('click', hideAll, false);
// Run hideAll
hideAll();
}
/* style span like link */
.linkLike {
text-decoration: underline;
cursor: pointer;
}
/* class to hide element */
.hidden {
visibility: hidden;
}
<ul id="a"><li>A</ul>
<ul id="b"><li>B</ul>
<ul id="c"><li>C</ul>
<ul id="d"><li>D</ul>
<div><span class="linkLike" data-id="a">Toggle A</span></div>
<div><span class="linkLike" data-id="b">Toggle B</span></div>
<div><span class="linkLike" data-id="c">Toggle C</span></div>
<div><span class="linkLike" data-id="d">Toggle D</span></div>
Of course there are other ways to do the association, but ID is simple, explicit and doesn't depend on document layout or formatting.

jQuery show unique popup for each link clicked

I have a series of links on my page, each link has a unique id: library_vid_link-UNIQUE_ID. When clicked, I want to show a popup which shows information unique to that link.
For each link, I have a hidden popup, which, when clicked, the popup is displayed. The popup also has a unique id: less_preview_popup-UNIQUE_ID (the unique id for the link and popup both match).
Here is a sample of my html code:
<a href="#" class="library_vid_link" id="library_vid_link-801">CLICK HERE FOR MORE INFO
</a>
<div class="lesson_preview_popup" id="lesson_preview_popup-801">
THIS IS THE POPUP
</div>
<a href="#" class="library_vid_link" id="library_vid_link-802">CLICK HERE FOR MORE INFO
</a>
<div class="lesson_preview_popup" id="lesson_preview_popup-802">
THIS IS THE POPUP 2
</div>
Here is the jquery i'm currently using:
jQuery('.library_vid_link').click(function( event ) {
event.preventDefault();
$('.lesson_preview_popup').css('top', '25%');
$('body').addClass('no-scroll');
});
The issue I'm having is that when I click on a link, ALL the popups show, not just the one that relates to the link clicked. Is there a way to target the popup that belongs to the link clicked?

Use the data-attribute:
<a data-popup="lesson_preview_popup_801" ....
And
$("#"+$(this).data("popup")).show().css('top', '25%');
Using $(this).next() instead, assumes that the div to show is the next sibling of the link

Change this:
$('.lesson_preview_popup').css('top', '25%');
into this:
$(this).next().css('top', '25%');
Alternatively, save the ID (e.g. 801) in a new attribute, like this:
<a data-id="801" ...
Then, call the popup like this:
jQuery('.library_vid_link').click(function( event ) {
event.preventDefault();
var thisId = $(this).attr("data-id"); //get "801"
$('#lesson_preview_popup-' + thisId).css('top', '25%'); //construct the ID and call the popup by its ID
$('body').addClass('no-scroll');
});

Jquery .next() select next sibling of element. Use it like bottom example
$('.library_vid_link').click(function( event ) {
event.preventDefault();
$(this).next().show().css('top', '25%');
$('body').addClass('no-scroll');
});
$('.library_vid_link').click(function( event ) {
//event.preventDefault();
$(this).next().show().css('top', '25%');
//$('body').addClass('no-scroll');
});
.lesson_preview_popup {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#" class="library_vid_link" id="library_vid_link-801">CLICK HERE FOR MORE INFO
</a>
<div class="lesson_preview_popup" id="lesson_preview_popup-801">
THIS IS THE POPUP
</div>
<a href="#" class="library_vid_link" id="library_vid_link-802">CLICK HERE FOR MORE INFO
</a>
<div class="lesson_preview_popup" id="lesson_preview_popup-802">
THIS IS THE POPUP 2
</div>

Dropdown menu should not be closed if it is clicked inside

I put a panel inside a bootstrap dropdown, but when I click inside the panel, the dropdown goes away. I got many solution on stackoverflow but it didn't work for me. How can i prevent panel from disappearing when i click inside.enter code here
<span class="input-group-addon dropdown">
<label class="dropdown-toggle " id="dropdownMenu1" data-toggle="dropdown aria-expanded="false">Advanced Search <span class="caret"></span></label>
<div class="panel panel-default panel-body dropdown-menu " role="menu"" aria-labelledby="dropdownMenu1" style="width:860px; margin-left:-700px">
Panel content
</div>
</span>

Try to do something like this:if you click on the body it checks the parent class,if you click on the dropdown if parent has class .dropdown-parentclass then the dropdown does not close.
$('body').click(function(event){
if ($(event.target).parent('.dropdown-parentclass').size()>0) {
return false;
}
});

try using the code below. It will close the dropdown only when you click out side the container.
$(document).on("mouseup", function (e) {
var container = $(".panel");
if (!container.is(e.target) // if the target of the click isn't the container
&& container.has(e.target).length === 0) // nor a descendant of the container
{
container.hide();
}
else {
}
});

Dropdown that hides on click outside of the menu

I've got a simple dropdown script and I want it to hide all open dropdowns on a click outside of the menu. But it does not seem to work, does anyone know why?

$(document).ready(function () {
$('.Navigation-listItem').click(function () {
$(this).children('.Navigation-list.is-dropdown').toggleClass('is-hidden');
});
/* Anything that gets to the document

$(document).on('click', function (event) {
if ($(event.target).closest('#menu').length == false) {
$(".Navigation-list.is-dropdown").addClass('is-hidden');
}
});
/* Clicks within the dropdown won't make
it past the dropdown itself */
$(".Navigation-listItem.is-dropdown ").click(function (e) {
e.stopPropagation();
});
});
With help from this answer

You can change the display property of your dropdown in this manner. This is just a rough code.
if(dropDownShow.css('display') != 'block'){
dropDownShow.css('display', 'block');
dropDownShow.css('position', 'absolute');
}
else{
dropDownShow.css('display', 'none');
}

With the info you gave and the codepen I can't see it working, but I suppose that $(document).click(function() to hide won't work because the drop down is inside the document so when you click it, it'll disappear. I recommend you to see this post How to hide/show drop down list content in HTML.

Twitter bootstrap stop propagation on dropdown open

I have a twitter bootstrap dropdown inside a div with the plugin jOrgChart.
The problem I'm having is that when I click the button to open the dropdown menu it also triggers a click event in the parent div that does a collapse of other elements.
This is my html:
<div id="chart">
<div class="node">
<div class="btn-group">
<a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
Actions
<span class="caret"></span>
</a>
<ul class="dropdown-menu" style="text-align:left;">
<li>Edit</li>
<li>Delete</li>
</ul>
</div>
</div>
<div class="node">
...
</div>
I want to prevent the click of a.dropdown-toggle from bubbling to div.node, I tried with this:
$("div#chart div.btn-group > a.dropdown-toggle").click(function (e) {
e.stopPropagation();
});
But now the dropdown isn't working.
EDIT
This is the concrete case: http://jsfiddle.net/UTYma/2/ (Thanks to Joe Tuskan for starting the fiddle)

$("#orgchart").jOrgChart({ chartElement: '#chart' });
$("div#chart div.btn-group > a.dropdown-toggle, .dropdown-menu li a").click(function(e) {
e.stopPropagation();
$('.dropdown-menu').toggle();
});​
Stop Propagation then toggle. Example
I had to add the drop down menu items to the click handler to keep the behavior constant.

Try something like this:
$("div#chart div.btn-group > a.dropdown-toggle").click(function (e) {
e.isDropDownToggleEvent =true;
})
Then:
$("div.node").click(function (e) {
if (e.isDropDownToggleEvent != null && e.isDropDownToggleEvent)
return false;
return true;
})
You can also try to put e.preventDefault() or e.stopPropagation(); instead of return false.

I used
$('.multiselect').on('click', function (e) {
$(this).next('.dropdown-menu').toggle();
e.stopPropagation();
});
This is similar to #Joe's answer, but a bit more generic

$("div#chart div.btn-group > a.dropdown-toggle, .dropdown-menu li a").click(function(e) {
e.stopPropagation();
$(this).closest('.dropdown').toggleClass('open');
});​
You should use this instead as above solution doesn't close the dropdown on focus out.

Building on Joe's answer, this includes the normal dropdown functionality of closing on the next click.
$("#orgchart").jOrgChart({ chartElement: '#chart' });
$("div#chart div.btn-group > a.dropdown-toggle, .dropdown-menu li a").click((e) => {
e.stopPropagation();
$('.dropdown-menu').toggle();
// close on next click only
$(window).one("click", () => $('.dropdown-menu').toggle());
});​

If I understand correctly, you want to avoid closing menu.
$("div#chart .dropdown-menu li").bind('click',function (e) {
e.stopPropagation();
},false);
