How to add class 'reverse' to dropdown-menu dynamically on dropdown click? - javascript

I am looking for a solution to add class reverse from ts file to show dropdown upward when it's near or in the bottom position.
On dropdown click, it gives me null for dropdown-menu in the console.
For now I am adding it through html, in addition it require a boolean variable to check for it's position. So, I am using many dropdowns in my project and I do not want to add such redundent approach every where.
Further, after its solution, I have to make a directive to use globally in my project.
Below is my code:
app.component.ts
upwardFlag = false
dropdownStatus() {
this.showDropDown = !this.showDropDown;
var scrollTop = document.documentElement.scrollTop;
var dropdown = document.querySelector('.dropdown-toggle')
var bodyRect = document.body.getBoundingClientRect().top,
offset = dropdown.getBoundingClientRect().top,
topOffset = offset - bodyRect;
var relativeOffset = topOffset - scrollTop;
var windowHeight = window.innerHeight;
var dropdownMenu = document.querySelector('.dropdown-menu')
if (relativeOffset > (windowHeight/2)) {
console.log('show upward', dropdownMenu);
this.upwardFlag = true
} else {
this.upwardFlag = false
console.log('show downward', dropdownMenu);
}
}
app.component.html
<div id="container">
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" #dp (click)="dropdownStatus()">
Cool dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu open" role="menu" aria-labelledby="dropdownMenu1" *ngIf="showDropDown" [ngClass]="{'showDropDown': 'open'}" [class.reverse]="upwardFlag===true">
<li role="presentation">Action</li>
<li role="presentation">Another action</li>
<li role="presentation">Something else here</li>
<li role="presentation" class="divider"></li>
<li role="presentation">Separated link</li>
</ul>
</div>
</div>
You can check it in this stackblitz

Angular has not yet created the HTML element when you query it, your code is faster than Angular template checking ;)
Two solutions
Make a reverse variable and do [class.reverse]="reverse" on your component.
Use [hidden]="!showDropdown" rather than *ngIf, then it will be available in the DOM.
By the way, you could use a #ViewChild('.myClass') dropdown : ElementRef; to access the element in a more "Angular Way".

javascript function is reset everytime I call a livewire action

What I'm trying to do is setting 'active' on the class of the button that was clicked, and on every other button remove the class 'active' if it was present in it, problem is everytime I click the button that isn't active, it gives the attribute 'active' and removes it from the other one for a second and then returns everything to how it was before I clicked.
My view:
<ul class="nav" id="myDIV">
<li class="nav-item active" wire:click="$emit('PaginaPrincipal')">
<a class="nav-link" href="#" onclick="event.preventDefault();" >
<i class="nc-icon nc-icon nc-paper-2"></i>
<p>Página Principal</p>
</a>
</li>
#foreach ($titulos as $titulo)
<li class="nav-item" wire:click="ViewNiveis">
<a class="nav-link" href="#" onclick="event.preventDefault();" >
<i class="nc-icon nc-icon nc-paper-2"></i>
<p>{{ $titulo }}</p>
</a>
</li>
#endforeach
My javascript:
var header = document.getElementById("myDIV");
var btns = header.getElementsByClassName("nav-item");
for (var i = 0; i < btns.length; i++)
{
btns[i].addEventListener("click", function()
{
var current = document.getElementsByClassName("active");
current[0].className = current[0].className.replace(" active", "");
this.className += " active";
});
}
After some trial and error I have found out that if I remove the livewire action that is inside the foreach it stops resetting itself, is there any way to stop it from resetting itself while still keeping my livewire action?
Thanks in advance.
Update:
I have tried other javascript functions online to see if the problem was some confusion between javascript and livewire, but it stills produces the same error.
try btns[i] instead of this in the event listener code.
You could also change the previous code to document.querySelector(‘.active’) instead of selecting all elements with the class name and then using index of 0 to select the first active element.

i want to show particular contents of view onclick of dropdown values without storing in database

i want to show particular contents of view onclick of dropdown values without storing in database
controller code is :
public ActionResult GuideView(int id)
{
HeaderViewModel model = new HeaderViewModel();
model.Guild = id;
return View(model);
}
navigation bar :
Diamond <b class="caret"></b>
Emerald <b class="caret"></b>
view is:
#if (Model.Guild == 1)
{
Diamond Carat Weight
<p>Carat: This one is easy: the bigger the diamond, the more it s worth and the more it costs (all other factors being equal). Diamonds are often listed with a per carat price, especially when buying on the internet or wholesale.<p>
As discussed, for a link in the view use...
#Url.Action("GuideView" , "Base", new { id = 2 })
If you are using bootstrap to create a list of dropdowns that launch an option, you can use the below.
<li class="dropdown">
Menu Options
<ul class="dropdown-menu">
<li role="presentation">
<a id="lnkMyOption1" class="dropdownitem" data-action="/Base/GuideView?id=1">Diamond</a>
</li>
<li role="presentation">
<a id="lnkMyOption2" class="dropdownitem" data-action="/Base/GuideView?id=2">Emerald</a>
</li>
</ul>
</li>
OK.. Then add the Jquery below to launch to the controller action.
<script>
$(document).ready(function () {
$(".dropdownitem").on('click', function () {
var route = $(this).data("action");
window.location = route;
});
});
</script>
Hope that helps

Href is not working on Edge or IE

I have this code,
<li class="centro-de-servicios col-md-3 col-xs-12 dropdown dropdown-toggle" data-toggle="dropdown">
<i class="icon-centro-de-servicios"></i>
Service Center <i class="arrow-down"></i>
<ul class="submenu dropdown-menu">
<li>Start</li>
<li>About Us</li>
<li>Our Policies</li>
<li>Maintenance</li>
<li>Quote a Visit</li>
<li>Service Tickets</li>
<!--<li></li>-->
<li>Advice</li>
<li>Contact</li>
</ul>
</li>
When i'm positioned on any element, and try to go to another page, the page is just refreshing, not changing. This happens only on Edge and IE.
I tried "window.location.href = 'url'", "location.href = 'url'", "location= 'url'", "location.replace('url')", etc, and there are not working, if a put a target blank it works, but i don't want the target blank.
You didn't close the url and put extra page="" in it.
Try it like this:
<li onclick = "location = 'http://beta.capris.cr/servicios/?page=centro-de-servicios&section=centro-de‌​-servicios'">Start</li>
EDIT:
Have a look at this code on your page:
jQuery(".submenu a").click(function () {
jQuery(location).attr(jQuery(this).attr("href"));
location.reload();
// setTimeout(function () {
// updatePage(currentPage, location.hash);
// }, 10);
});

Collapsing multiple navbar bootstrap

I have followed this example http://jsfiddle.net/rDN3P/98/ to create a collapsing navbar. It is working fine as long as I have one level in my menu. The collapsing seems not to work if I have multiple level of menu.
In this example, if you open the collapsible menu and click on the second 'dropdown2' item in the menu you will know what I mean.
This structure is the issue I assume
<li class="dropdown">
Dropdown <span class="caret"></span>
<ul class="dropdown-menu" role="menu">
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
Dropdown2
<span class="caret"></span>
</a>
<ul class="dropdown-menu" role="menu">
<li>Action sub</li>
</ul>
</li>
Solved: jsfiddle
Based on this answer to add the third level menu with a little modification of the js code to close the third level menu on click:
$('ul.dropdown-menu [data-toggle=dropdown]').on('click', function(event) {
// Avoid following the href location when clicking
event.preventDefault();
// Avoid having the menu to close when clicking
event.stopPropagation();
// If a menu is already open we close it
if($(this).parent().hasClass('open')){
$('ul.dropdown-menu [data-toggle=dropdown]').parent().removeClass('open');
}else{
// opening the one you clicked on
$(this).parent().addClass('open');
var menu = $(this).parent().find("ul");
var menupos = menu.offset();
if ((menupos.left + menu.width()) + 30 > $(window).width()) {
var newpos = - menu.width();
} else {
var newpos = $(this).parent().width();
}
menu.css({ left:newpos });
}
});
<li class="dropdown">
Dropdown <span class="caret"></span>
<ul class="dropdown-menu">
<li class="dropdown-submenu">
<a href="#">
Dropdown2
</a>
<ul class="dropdown-menu" role="menu">
<li>Action sub</li>
</ul>
</li>
The nesting should be done properly I guess, with the correct classes.

Avoid dropdown menu close on click inside

I have a Twitter Bootstrap dropdown menu. As all Twitter Bootstrap users know, the dropdown menu closes on click (even clicking inside it).
To avoid this, I can easily attach a click event handler on the dropdown menu and simply add the famous event.stopPropagation().
<ul class="nav navbar-nav">
<li class="dropdown mega-dropdown">
<a href="javascript:;" class="dropdown-toggle" data-toggle="dropdown">
<i class="fa fa-list-alt"></i> Menu item 1
<span class="fa fa-chevron-down pull-right"></span>
</a>
<ul class="dropdown-menu mega-dropdown-menu">
<li>
<div id="carousel" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<li data-slide-to="0" data-target="#carousel"></li>
<li class="active" data-slide-to="1" data-target="#carousel"></li>
</ol>
<div class="carousel-inner">
<div class="item">
<img alt="" class="img-rounded" src="img1.jpg">
</div>
<div class="item active">
<img alt="" class="img-rounded" src="img2.jpg">
</div>
</div>
<a data-slide="prev" role="button" href="#carousel"
class="left carousel-control">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a data-slide="next" role="button" href="#carousel"
class="right carousel-control">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
</div>
</li>
</ul>
</li>
</ul>
This looks easy and a very common behavior, however, and since carousel-controls (as well as carousel indicators) event handlers are delegated to the document object, the click event on these elements (prev/next controls, ...) will be “ignored”.
$('ul.dropdown-menu.mega-dropdown-menu').on('click', function(event){
// The event won't be propagated up to the document NODE and
// therefore delegated events won't be fired
event.stopPropagation();
});
Relying on Twitter Bootstrap dropdown hide/hidden events is not a solution for the following reasons:
The provided event object for both event handlers does not give reference to the clicked element
I don't have control over the dropdown menu content so adding a flag class or attribute is not possible
This fiddle is the normal behavior and this fiddle is with event.stopPropagation() added.
Update
Thanks to Roman for his answer. I also found an answer that you can find below.
This should help as well
$(document).on('click', 'someyourContainer .dropdown-menu', function (e) {
e.stopPropagation();
});
Removing the data attribute data-toggle="dropdown" and implementing the open/close of the dropdown can be a solution.
First by handling the click on the link to open/close the dropdown like this :
$('li.dropdown.mega-dropdown a').on('click', function (event) {
$(this).parent().toggleClass('open');
});
and then listening the clicks outside of the dropdown to close it like this :
$('body').on('click', function (e) {
if (!$('li.dropdown.mega-dropdown').is(e.target)
&& $('li.dropdown.mega-dropdown').has(e.target).length === 0
&& $('.open').has(e.target).length === 0
) {
$('li.dropdown.mega-dropdown').removeClass('open');
}
});
Here is the demo :
http://jsfiddle.net/RomaLefrancois/hh81rhcm/2/
The absolute best answer is to put a form tag after the class dropdown-menu
so your code is
<ul class="dropdown-menu">
<form>
<li>
<div class="menu-item">bla bla bla</div>
</li>
</form>
</ul>
Bootstrap provides the following function:
| This event is fired immediately when the hide instance method
hide.bs.dropdown | has been called. The toggling anchor element is available as the
| relatedTarget property of the event.
Therefore, implementing this function should be able to disable the dropdown from closing.
$('#myDropdown').on('hide.bs.dropdown', function (e) {
var target = $(e.clickEvent.target);
if(target.hasClass("keepopen") || target.parents(".keepopen").length){
return false; // returning false should stop the dropdown from hiding.
}else{
return true;
}
});
This might help:
$("dropdownmenuname").click(function(e){
e.stopPropagation();
})
I just add onclick event like below to not close dropdown-menu.
<div class="dropdown-menu dropdown-menu-right" onclick="event.stopPropagation()" aria-labelledby="triggerId">
I also found a solution.
Assuming that the Twitter Bootstrap Components related events handlers are delegated to the document object, I loop the attached handlers and check if the current clicked element (or one of its parents) is concerned by a delegated event.
$('ul.dropdown-menu.mega-dropdown-menu').on('click', function(event){
var events = $._data(document, 'events') || {};
events = events.click || [];
for(var i = 0; i < events.length; i++) {
if(events[i].selector) {
//Check if the clicked element matches the event selector
if($(event.target).is(events[i].selector)) {
events[i].handler.call(event.target, event);
}
// Check if any of the clicked element parents matches the
// delegated event selector (Emulating propagation)
$(event.target).parents(events[i].selector).each(function(){
events[i].handler.call(this, event);
});
}
}
event.stopPropagation(); //Always stop propagation
});
Hope it helps any one looking for a similar solution.
Thank you all for your help.
In the new Bootstrap 5 the solution is trivially simple.
Quote from the documentation page:
By default, the dropdown menu is closed when
clicking inside or outside the dropdown menu. You can use the
autoClose option to change this behavior of the dropdown.
In addition to the default behavior, we have 3 options available here:
Clickable outside: data-bs-auto-close="outside"
Clickable inside: data-bs-auto-close="inside"
Manual close: data-bs-auto-close="false"
E.g.:
<div class="btn-group">
<button class="btn btn-secondary dropdown-toggle" data-bs-auto-close="inside" type="button" id="dropdownMenuClickableInside" data-bs-toggle="dropdown" aria-expanded="false">
Clickable inside
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenuClickableInside">
<li><a class="dropdown-item" href="#">Menu item</a></li>
<li><a class="dropdown-item" href="#">Menu item</a></li>
<li><a class="dropdown-item" href="#">Menu item</a></li>
</ul>
</div>
More info: https://getbootstrap.com/docs/5.1/components/dropdowns/#auto-close-behavior
$('body').on("click", ".dropdown-menu", function (e) {
$(this).parent().is(".open") && e.stopPropagation();
});
This may work for any conditions.
I tried this simple thing and it worked like a charm.
I changed the dropdown-menu element from <div> to <form> and it worked well.
<div class="nav-item dropdown" >
<a href="javascript:;" class="nav-link dropdown-toggle" data-toggle="dropdown">
Click to open dropdown
</a>
<form class="dropdown-menu ">
<ul class="list-group text-black">
<li class="list-group-item" >
</li>
<li class="list-group-item" >
</li>
</ul>
</form>

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<div class="nav-item dropdown" >
<a href="javascript:;" class="nav-link dropdown-toggle" data-toggle="dropdown">
Click to open dropdown
</a>
<form class="dropdown-menu ">
<ul class="list-group text-black">
<li class="list-group-item" >
List Item 1
</li>
<li class="list-group-item" >
LI 2<input class="form-control" />
</li>
<li class="list-group-item" >
List Item 3
</li>
</ul>
</form>
jQuery:
<script>
$(document).on('click.bs.dropdown.data-api', '.dropdown.keep-inside-clicks-open', function (e) {
e.stopPropagation();
});
</script>
HTML:
<div class="dropdown keep-inside-clicks-open">
<button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">
Dropdown Example

Your demo with this solution: http://jsfiddle.net/kerryjohnson/80oLdtbf/101/
I modified #Vartan's answer to make it work with Bootstrap 4.3. His solution doesn't work anymore with the latest version as target property always returns dropdown's root div no matter where the click was placed.
Here is the code:
$('.dropdown-keep-open').on('hide.bs.dropdown', function (e) {
if (!e.clickEvent) {
// There is no `clickEvent` property in the `e` object when the `button` (or any other trigger) is clicked.
// What we usually want to happen in such situations is to hide the dropdown so we let it hide.
return true;
}
var target = $(e.clickEvent.target);
return !(target.hasClass('dropdown-keep-open') || target.parents('.dropdown-keep-open').length);
});
<div class="dropdown dropdown-keep-open">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown button
</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</div>
$('body').on("click", ".dropdown-menu", function (e) {
$(this).parent().is(".show") && e.stopPropagation();
});
Like for instance Bootstrap 4 Alpha has this Menu Event. Why not use?
// PREVENT INSIDE MEGA DROPDOWN
$('.dropdown-menu').on("click.bs.dropdown", function (e) {
e.stopPropagation();
e.preventDefault();
});
You can also use form tag. Example:
<div class="dropdown-menu">
<form>
Anything inside this wont close the dropdown!
<button class="btn btn-primary" type="button" value="Click me!"/>
</form>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Clik this and the dropdown will be closed</a>
<a class="dropdown-item" href="#">This too</a>
</div>
Source: https://getbootstrap.com/docs/5.0/components/dropdowns/#forms
Bootstrap 5
If anyone comes to this via Google wanting a Bootstrap 5 version like I was, it's built in by adding data-bs-auto-close="outside". Note the option is autoClose but when passing as a data attribute the camelcasing is removed & separated by a dash.
I have a collapse widget in a dropdown & adding data-bs-auto-close="outside" to the parent data-bs-toggle="dropdown" trigger keeps the dropdown open while the collapse is toggled.
See official Bootstrap docs: https://getbootstrap.com/docs/5.1/components/dropdowns/#options
And this codepen for example code (not my pen): https://codepen.io/SitePoint/pen/BaReWGe
I've got a similar problem recently and tried different ways to solve it with removing the data attribute data-toggle="dropdown" and listening click with event.stopPropagation() calling.
The second way looks more preferable. Also Bootstrap developers use this way.
In the source file I found initialization of the dropdown elements:
// APPLY TO STANDARD DROPDOWN ELEMENTS
$(document)
.on('click.bs.dropdown.data-api', clearMenus)
.on('click.bs.dropdown.data-api', '.dropdown form', function (e) { e.stopPropagation() })
.on('click.bs.dropdown.data-api', toggle, Dropdown.prototype.toggle)
.on('keydown.bs.dropdown.data-api', toggle, Dropdown.prototype.keydown)
.on('keydown.bs.dropdown.data-api', '.dropdown-menu', Dropdown.prototype.keydown)
}(jQuery);
So, this line:
.on('click.bs.dropdown.data-api', '.dropdown form', function (e) { e.stopPropagation() })
suggests you can put a form element inside the container with class .dropdown to avoid closing the dropdown menu.
Bootstrap has solved this problem themselves in their support for <form> tags in dropdowns. Their solution is quite graspable and you can read it here: https://github.com/twbs/bootstrap/blob/v4-dev/js/src/dropdown.js
It boils down to preventing propagation at the document element and doing so only for events of type 'click.bs.dropdown.data-api' that match the selector '.dropdown .your-custom-class-for-keep-open-on-click-elements'.
Or in code
$(document).on('click.bs.dropdown.data-api', '.dropdown .keep-open-on-click', (event) => {
event.stopPropagation();
});
You could simply execute event.stopPropagation on click event of the links themselves.
Something like this.
$(".dropdown-menu a").click((event) => {
event.stopPropagation()
let url = event.target.href
//Do something with the url or any other logic you wish
})
Edit: If someone saw this answer and is using react, it will not work.
React handle the javascript events differently and by the time your react event handler is being called, the event has already been fired and propagated. To overcome that you should attach the event manually like that
handleMenuClick(event) {
event.stopPropagation()
let menu_item = event.target
//implement your logic here.
}
componentDidMount() {
document.getElementsByClassName("dropdown-menu")[0].addEventListener(
"click", this.handleMenuClick.bind(this), false)
}
}
You can stop click on the dropdown from propagating and then manually reimplement the carousel controls using carousel javascript methods.
$('ul.dropdown-menu.mega-dropdown-menu').on('click', function(event) {
event.stopPropagation();
});
$('a.left').click(function () {
$('#carousel').carousel('prev');
});
$('a.right').click(function () {
$('#carousel').carousel('next');
});
$('ol.carousel-indicators li').click(function (event) {
var index = $(this).data("slide-to");
$('#carousel').carousel(index);
});
Here is the jsfiddle.
demo: http://jsfiddle.net/4y8tLgcp/
$('ul.nav.navbar-nav').on('click.bs.dropdown', function(e){
var $a = $(e.target), is_a = $a.is('.is_a');
if($a.hasClass('dropdown-toggle')){
$('ul.dropdown-menu', this).toggle(!is_a);
$a.toggleClass('is_a', !is_a);
}
}).on('mouseleave', function(){
$('ul.dropdown-menu',this).hide();
$('.is_a', this).removeClass('is_a');
});
i have updated it once again to be the smartest and functional as possible. it now close when you hover outside the nav, remaining open while you are inside it. simply perfect.
I know there already is a previous answer suggesting to use a form but the markup provided is not correct/ideal. Here's the easiest solution, no javascript needed at all and it doesn't break your dropdown. Works with Bootstrap 4.
<form class="dropdown-item">
<!-- Your elements go here -->
</form>
I know this question was specifically for jQuery, but for anyone using AngularJS that has this problem you can create a directive that handles this:
angular.module('app').directive('dropdownPreventClose', function() {
return {
restrict: 'A',
link: function(scope, element, attrs) {
element.on('click', function(e) {
e.stopPropagation(); //prevent the default behavior of closing the dropdown-menu
});
}
};
});
Then just add the attribute dropdown-prevent-close to your element that is triggering the menu to close, and it should prevent it. For me, it was a select element that automatically closed the menu:
<div class="dropdown-menu">
<select dropdown-prevent-close name="myInput" id="myInput" ng-model="myModel">
<option value="">Select Me</option>
</select>
</div>
With Angular2 Bootstrap, you can use nonInput for most scenarios:
<div dropdown autoClose="nonInput">
nonInput - (default) automatically closes the dropdown when any of its elements is clicked — as long as the clicked element is not an input or a textarea.
https://valor-software.com/ng2-bootstrap/#/dropdowns
[Bootstrap 4 Alpha 6][Rails]
For rails developer, e.stopPropagation() will lead to undesirable behavior for link_to with data-method not equal to get since it will by default return all your request as get.
To remedy this problem, I suggest this solution, which is universal
$('.dropdown .dropdown-menu').on('click.bs.dropdown', function() {
return $('.dropdown').one('hide.bs.dropdown', function() {
return false;
});
});
$('.dropdown .dropdown-menu').on('click.bs.dropdown', function() {
return $('.dropdown').one('hide.bs.dropdown', function() {
return false;
});
});

This helped me,
$('.dropdown-menu').on('click', function (e) {
if ($(this).parent().is(".open")) {
var target = $(e.target);
if (target.hasClass("keepopen") || target.parents(".keepopen").length){
return false;
}else{
return true;
}
}
});
Your drop down menu element needs to be like this, (take a note of the classes dropdown-menu and keepopen.
<ul role="menu" class="dropdown-menu topmenu-menu eserv_top_notifications keepopen">
The above code prevents biding on the whole <body>, instead to the specfic element with the class dropdown-menu.
Hope this helps someone.
Thanks.
The simplest working solution for me is:
adding keep-open class to elements that should not cause dropdown closing
and this piece of code do the rest:
$('.dropdown').on('click', function(e) {
var target = $(e.target);
var dropdown = target.closest('.dropdown');
return !dropdown.hasClass('open') || !target.hasClass('keep-open');
});
I've found none of the solutions worked as I would like using default bootstrap nav.
Here is my solution to this problem:
$(document).on('hide.bs.dropdown', function (e) {
if ($(e.currentTarget.activeElement).hasClass('dropdown-toggle')) {
$(e.relatedTarget).parent().removeClass('open');
return true;
}
return false;
});
Instead of writing some javascript or jquery code(reinventing the wheel). The above scenario can be managed by bootstrap auto-close option.
You can provide either of the values to auto-close:
always - (Default) automatically closes the dropdown when any of its elements is clicked.
outsideClick - closes the dropdown automatically only when the user clicks any element outside the dropdown.
disabled - disables the auto close
Take a look at the following plunkr :

Set
uib-dropdown auto-close="disabled"
Hope this helps :)
In .dropdown content put the .keep-open class on any label like so:
$('.dropdown').on('click', function (e) {
var target = $(e.target);
var dropdown = target.closest('.dropdown');
if (target.hasClass('keep-open')) {
$(dropdown).addClass('keep-open');
} else {
$(dropdown).removeClass('keep-open');
}
});
$(document).on('hide.bs.dropdown', function (e) {
var target = $(e.target);
if ($(target).is('.keep-open')) {
return false
}
});
The previous cases avoided the events related to the container objects, now the container inherits the class keep-open and check before being closed.
