Hide bootstrap's .dropdown-backdrop, CSS only - javascript

Is it possible to hide Bootstrap's .dropdown-backdrop element for a certain dropdown (not all on the page) by using CSS only?
I've determined that this is possible using Javascript, with JSFiddle here. However, I would like to accomplish this without using additional JS if possible.
<!-- First dropdown: no backdrop -->
<div id="firstDropdown" class="dropdown">
<button class="btn-dropdown-add btn btn-blue" data-toggle="dropdown">
First Dropdown ▼
</button>
<ul class="dropdown-menu" role="menu">
<li><a class="a_dropdown_item" href="#business">Business</a></li>
<li><a class="a_dropdown_item" href="#my-events">Event</a></li>
</ul>
</div>
<!-- Second dropdown: yes backdrop -->
<div id="secondDropdown" class="dropdown">
<button class="btn-dropdown-add btn btn-blue" data-toggle="dropdown">
Second Dropdown ▼
</button>
<ul class="dropdown-menu" role="menu">
<li><a class="a_dropdown_item" href="#business">Business</a></li>
<li><a class="a_dropdown_item" href="#my-events">Event</a></li>
</ul>
</div>
<script type="text/javascript">
// Hide backdrop from #firstDropdown.
// This can be done with JS as below. Can it be done with only CSS?
$('#firstDropdown').on('show.bs.dropdown', function () {
$(".dropdown-backdrop").hide();
});
</script>

Found solution: .dropdown-backdrop is a descendant of its .dropdown, which can have a unique ID, so simply using display:none; in CSS works fine, as in:
#firstDropdown .dropdown-backdrop {
display:none;
}
And then all other dropdowns (except #firstDropdown) will still have a backdrop as normal.
See JSFiddle updated.

Bootstrap button dropdown child element's class is getting removed when clicked on other button's dropdown items

Here is the fiddle.
What I am trying to do is use Bootstrap's drop-down menu instead of select boxes and utilize list items instead of option. The data that is being retrieved from selected list item and put into its corresponding button element is given a class of 'active-select' on a click event (shown in blue after it renders). Like this:
<li><a href="#" class="active-select">New York<a><li>
Clicking on other list item should remove the above mentioned class from other list items only within the corresponding button element. But the class is being removed from the selected list item from other button drop-down group as well. Like this:
<li><a href="#" class>New York<a><li>
Can anyone please help?
The problem occurs because you are using parents instead of parent:
This line of code is the problem:
thisEl.parents('li').siblings().find('a').removeClass('active-select'); // parents targets all li's above `a` and hence siblings afterwards targets other drop-downs.
Instead use parent like this:
thisEl.parent('li').siblings().find('a').removeClass('active-select');
Full working code
(function () {
var search_btn = $('.select-style').find('button.btn-inverse'),
selectOptions = $('.select-style ul.dropdown-menu li').find('a');
selectOptions.on('click', function (e) {
e.preventDefault();
var thisEl = $(this);
var getTextData = thisEl.text();
thisEl.addClass('active-select');
// Use .parent and not .parents
thisEl.parent('li').siblings().find('a').removeClass('active-select');
thisEl.parents('.btn-group').find('button[type=button]').html( getTextData );
});
}) ();
ul.homeInputBaropenState { list-style-type: none; width: 500px; }
ul.homeInputBaropenState li { display: inline; }
ul.homeInputBaropenState li a.active-select { color: blue; }

Protractor - Select from Bootstrap Dropdown

I have a Bootstrap single-button dropdown and I would like to click on one of the options appearing in the dropdown using Protractor. How do I accomplish this?
<div class="btn-group" ng-if="!persist.edit" dropdown>
<button type="button"
class="btn btn-default"
dropdown-toggle>
<span translate="GENERAL.ACTIONS"></span>
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu">
<!-- Check In -->
<li role="presentation">
<a ng-click="checkIn()"
role="menuitem"
tabindex="-1"
translate="ITEMS.LIST.BUTTON_CHECK_ITEM_IN">
</a>
</li>
<!-- Check Out -->
<li role="presentation"">
<a ng-click="checkOut()"
role="menuitem"
tabindex="-1"
translate="ITEMS.LIST.BUTTON_CHECK_ITEM_OUT"
translate-value-length="1">
</a>
</li>
</ul>
</div>
I tried this (dropdown is called, but click fails):
it('Should click Actions button and show dropdown', function(){
element(by.buttonText("Actions")).click();
browser.sleep(1000);
});
it('Should click the Check Item Out dropdown option and change status to checked out', function(){
element(by.css('[value="ITEMS.LIST.BUTTON_CHECK_ITEM_OUT"]')).click();
});
First, click the "dropdown toggle" button to open up the dropdown. Then, select an option:
var dropDown = element(by.css("div[dropdown]"));
dropDown.element(by.css("button[dropdown-toggle]")).click();
dropDown.element(by.css("a[ng-click*=checkIn]")).click(); // Check In
Working code:
element(by.buttonText("Actions")).click();
element(by.css('[ng-click="]checkIn()"]')).click(); // Check In
A clean solution to select from Bootstrap Dropdown is to click by buttonText and then by linkText:
element(by.buttonText('your button')).click();
element(by.linkText('your selection')).click();

Bootstrap Dropdown + Angular data-ng-repeat

I'm having a little issue while trying to show some data (Villains/Villanos) in a drop down with a ng-repeat. I've been looking around and trying but I can't make it work. I have the following HTML:
<script src="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.7/angular.min.js" </script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.7/angular-animate.js"></script>
<script>
// This function lets the dropdown button save the name of the Villain that it's selected.
$(function(){
$(".dropdown-menu li a").click(function(){
$(".dropdown-toggle:first-child").text($(this).text());
$(".dropdown-toggle:first-child").val($(this).text());
});
});
</script>
<div class="dropdown">
<button class="btn btn-default dropdown-toggle dropdown-suspects-sides" type="button" id="dropdownMenu1" data-toggle="dropdown">
Suspects
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">
<li class="suspect" role="presentation" data-ng-repeat = "villain in villains">
<a role="menuitem" tabindex="-1" href="#">
<span class="glyphicon glyphicon-user"></span> {{villain}}
</a>
</li>
</ul>
</div>
/* Controllers */
...
$scope.getVillains = function() {
$http.get("/getVillains")
.success(function(data) {
$scope.villains = data
}
)
};
...
As you can see, I'm trying to make a dropdown to show all the Villains I have. The items appear correctly if they're showed in a normal list so the items can be "used", but they're not appearing if I try to show them this way. I'm pretty sure I'm doing something wrong here but I can't guess what is it. Thanks in advance!

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>

<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">

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.
