bootstrap toggle dropdown from within javascript - javascript

I have a bootstrap 4 dropdown menu that expands (toggles) on hover instead of a click. On a click a link is followed. (I know, this is bad practice). Now I am trying to achieve that on touch-enabled devices, the link is never followed and on a click or touch the dropdown is toggled.
I have managed to disable the link, but I can't seem to toggle the menu. This is what I tried:
JS
var button = jQuery('.btn-dropdown-link');
if ('ontouchstart' in window) {
button.click(function (e) {
e.preventDefault();
console.log('clicked / touched');
jQuery('#dropdownMenuButton').dropdown('toggle'); // this does not work?
});
}
HTML
<ul>
<li class="btn dropdown" id="dropdownMenuButton" aria-haspopup="true" aria-expanded="false">
<a class="btn btn-dropdown-link dropdown-toggle" href="/com">some link</a>
<ul class="dropdown-menu" id="dropdownDonateMenu" aria-labelledby="dropdownMenuButton">
<li>example</li>
<li>example</li>
<li>example</li>
</ul>
</li>
</ul>
CSS
.dropdown:hover > .dropdown-menu {
max-height: 500px;
opacity: 1;
}
.dropdown .dropdown-menu {
transition: all 0.3s;
max-height: 0;
display: block;
overflow: hidden;
opacity: 0;
min-width: 100%;
}
Or a live example on codeply.
How can I toggle the dropdown when I use e.preventDefault(); to block the link?
Edit: I have to use JS

You can add the :active on css on the same place you have the :hover
and on the HTML you can simply remove the href
something like this on the CSS:
.dropdown::active > .dropdown-menu, .dropdown::active > .dropdown-menu {
max-height: 500px;
opacity: 1;
}
and on the HTML you can simply remove the

You can do that using d-**-none and d-**-block on the break point which you wanna show
.dropdown:hover>.dropdown-menu {
display: block;
width: fit-content;
}

Multi-level bootstrap Navbar: Can't hover on children elements

So I'm trying to make a multi-level navbar in my project using Bootstrap Navbar with additional CSS and Jquery.
Here are the codes:
CodePen
$(function() {
// ------------------------------------------------------- //
// Multi Level dropdowns
// ------------------------------------------------------ //
$("ul.dropdown-menu [data-toggle='dropdown']").on("mouseover", function(event) {
event.preventDefault();
event.stopPropagation();
$(this).siblings().toggleClass("show");
});
$("ul.dropdown-menu [data-toggle='dropdown']").on("mouseleave", function(event) {
$(this).siblings().removeClass("show");
});
});
.dropdown-submenu {
position: relative;
}
.dropdown-submenu>a:after {
content: "\f0da";
float: right;
border: none;
font-family: 'FontAwesome';
}
.dropdown-submenu>.dropdown-menu {
top: 0;
left: 100%;
margin-top: 0px;
margin-left: 0px;
}
.dropdown-item {
padding: .25rem 0.5rem!important;

The problem is I can't hover on children like CF1, CF2, CF3,... and so on. When I move the mouse out of its parent element (which is Ceiling Fans), the sub-menu disappears.
Just Add This CSS
.dropdown-submenu:hover .dropdown-menu {
display: block;
}

overflow is sending dropdown behind the parent div while using li, z-index is not working

folks, I can't seem to figure out why overflow is breaking the code
so below code works fine in two conditions.
a) if I remove overflow-x and overflow-y from .bs-exmple or
b) if I remove ul and li
but I need both in my code, however with these css and ul and li being in code, the dropdown collapses behind the div. what am i missing
.bs-example { border: 1px solid black; overflow-y: scroll; overflow-x: hidden; min-height: 100px; max-height: 250px; }
.bs-example .dropdown { position: absolute; z-index: 999; }

Hiding dropdown menu on hover issues

I can see that this question has been asked a bit although I've found no solution that fixes my specific problem.
I have a sub menu within a menu that doesn't work as intended, it simply needs to be shown when hovered over and then when it's not hovered over, hide the sub menu.
Right now I can hover over the menu item but then when I got to select the next option it disappears.
I don't know where I'm going wrong, I know it's a simple feature yet it's driving me mad! here's my working below:
$(document).ready(function() {
$('.dropdown-submenu a.subhover').on("mouseover", function(e) {
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
});
});
$(document).ready(function() {
$('.dropdown-submenu a.subhover').on("mouseleave", function(e) {
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
});
});
.dropdown-submenu {
position: relative;
}
.dropdown-submenu .dropdown-menu {
top: 0;
left: 100%;
margin-top: -1px;
display: hidden;
}
.dropdown-submenu:hover .dropdown-menu {
display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<li class="dropdown menu-btn">
<a id=t estmanage class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">
<i class="fa fa-database fa-lg "></i> Manage <span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a id="btn_addnew" href="#">Create Audit</a></li>
<li>Departments</li>
<li>Products</li>
<li class="dropdown-submenu">
<a class="subhover" tabindex="-1" href="#"> Data Entry <span class="caret"></span></a>
<ul style="display: none;" class="dropdown-menu">
<li> Labour Costs </li>
<li> Purchases </li>
<li style="cursor: pointer;"><a data-toggle="modal" data-target="#salesModal">Sales</a></li>
<li> Wastage </li>
</ul>
</li>
</ul>
</li>
Forgive me for the formatting of the HTML part, can't get it to look like how it displays on my editor!
This can be done using CSS-Only. Just take a look at my solution:
.dropdown-submenu .dropdown-menu {
top: 0;
left: 100%;
margin-top: -1px;
display: none;
}
.subhover:hover ~ .dropdown-menu, .dropdown-menu:hover {
display: block;
}
<li class="dropdown menu-btn">
<a id=t estmanage class="dropdown-toggle" href="#" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">
<i class="fa fa-database fa-lg "></i> Manage <span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a id="btn_addnew" href="#">Create Audit</a></li>
<li>Departments</li>
<li>Products</li>
<li class="dropdown-submenu">
<a class="subhover" tabindex="-1" href="#"> Data Entry <span class="caret"></span></a>
<ul class="dropdown-menu">
<li> Labour Costs </li>
<li> Purchases </li>
<li style="cursor: pointer;"><a data-toggle="modal" data-target="#salesModal">Sales</a></li>
<li> Wastage </li>
</ul>
</li>
</ul>
</li>
And in this fiddle, both dropdowns are working together: https://jsfiddle.net/thau2g9j/13/
It's not working because you are executing same lines of code on mouseover and mouseleave. The below code is not required. Comment and check, if that should suffice you requirement.
$(document).ready(function() {
$('.dropdown-submenu a.subhover').on("mouseleave", function(e) {
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
});
});
Below is the running code snippet:
$(document).ready(function() {
$('.dropdown-submenu a.subhover').on("mouseover", function(e) {
$(this).next('ul').toggle();
e.stopPropagation();
e.preventDefault();
});
});
//$(document).ready(function() {
// $('.dropdown-submenu a.subhover').on("mouseleave", function(e) {
// $(this).next('ul').toggle();
// e.stopPropagation();
// e.preventDefault();
// });
//});
.dropdown-submenu {
position: relative;
}
.dropdown-submenu .dropdown-menu {
top: 0;
left: 100%;
margin-top: -1px;
display: hidden;
}
.dropdown-submenu:hover .dropdown-menu {
display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<li class="dropdown menu-btn">
<a id=t estmanage class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">
<i class="fa fa-database fa-lg "></i> Manage <span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a id="btn_addnew" href="#">Create Audit</a></li>
<li>Departments</li>
<li>Products</li>
<li class="dropdown-submenu">
<a class="subhover" tabindex="-1" href="#"> Data Entry <span class="caret"></span></a>
<ul style="display: none;" class="dropdown-menu">
<li> Labour Costs </li>
<li> Purchases </li>

Multilevel Navbar on Bootstrap 4 (Bootswatch) on right side

So I have a multilevel Navbar in Bootswatch 4 (Bootstrap 4) on the right sid in the desktop version (which I took from an example without really understanding the CSS and Javascript behind it) and I want to pop the Submenus open to the left side as normally works with "dropdown-menu-right" which doesn't help here. How can I still make the Submenus pop open to the left? Can someone help me how the CSS / Javascript could look like that it can work that way?

You need to adjust the left position of the submenus...

New to bootstrap. Here's the code based on the Bootstrap example. Right now the dropdown shows up but you're not able to click on the dropdown itself. I want to be able to make all the parent nav links work. Similar to this website: https://eastcfashion.com/
Where clicking on for example: men's collection brings you to all the collection for that area. But the dropdown menu, you're able to just go on specific items.
I'm trying to implement it in a way that the main parent nav would say Projects. and the dropdown menu for projects would show specific pages for each project like project 1, project 2, etc. But clicking on Projects would take you to a page where project 1, project 2, and the collection of projects would be showing as a group and not individually.

The easiest way to do it is by deleting the "data-toggle" attribute from the parent element!
edit: thx for the tip, here is a code example:
I changed this:
<a class="p-2 text-dark dropdown-toggle" data-toggle="dropdown" style="font-size:1.25rem;" href= {% url 'link' %}>Link</a>
to this:
<a class="p-2 text-dark dropdown-toggle" style="font-size:1.25rem;" href= {% url 'link' %}>Link</a>
so, in essence, I simply deleted the data toggle attribute and thus converted a hoverable dropdown into a hoverable dropdown with a clickable parent link.
I tried to keep the code simple. My solution is to detect the second click on the dropdown button/link and follow the link at that point.
$('.navbar .dropdown > a').click(function() {
if (!$(this).hasClass("parent-clicked")) {
$(this).addClass("parent-clicked");
} else {
location.href = this.href;
}
});
This works in the collapsed view as well.
I took Joe's answer and improved it to my needs
/*
* Only go to the link when dropdown is already open (if the dropdown is a link)
*/
$('.navbar ul.navbar-nav > .dropdown > a[href]').click(function() {
var dropdown = $(this).next('.dropdown-menu');
/*
* The dropdown can be non-existent
* The dropdown can be already open by css
* (for instance display: block from a custom :hover setting)
* or a "show" class on the element which also sets a display: block;
*/
if (dropdown.length == 0 || $(dropdown).css('display') !== 'none') {
if (this.href) {
location.href = this.href;
}
}
});
The Bootstrap 4 html for this is
<header class="navbar">
<ul class="nav navbar-nav">
<li class="nav-item dropdown">
<a class="nav-link" href="/planning" data-toggle="dropdown">
Planning
</a>
<ul class="dropdown-menu">
<li class="dropdown-item">
Day planning
</li>
</ul>
</li>
</ul>
</header>
Clickable dropdown link in Bootstrap 4
I hide the original dropdown triangle icon and make a new plus icon because the original icon is very small and made with pseudo-class :after, it's hard for user to point the cursor and click it.
So the parent href link will work as normal but when user click on plus icon it will open the dropdown.
/* -----------------------------------------------------------------------
Make Bootstrap dropdown "a" link clickable
But when clicking plus icon, show the dropdown
--------------------------------------------------------------------------- */
function clickableDropdownLink() {
if (window.matchMedia("(max-width: 992px)").matches) {
const dropdownToggle = $('.navbar .dropdown > a');
dropdownToggle.append('<span class="dropdown-icon"></span>');
dropdownToggle.removeAttr('data-toggle');
$('.navbar .dropdown > a').click(function(e) {
e.preventDefault();
if ((e.target.tagName == 'A')) {
const route = $(this).attr("href");
window.location.href = route == '/' || route == '#' ? window.location.href : route;
return;
}
})
const dropdownIcon = $('.navbar .dropdown > a > span.dropdown-icon');
dropdownIcon.click(function() {
const parentLink = $(this).parent("a.nav-link");
parentLink.parent(".nav-item").toggleClass("show");
parentLink.next(".dropdown-menu").toggle();
})
}
}
clickableDropdownLink();
/* ------------------------------------------------------------------------------------
This is optional, this could make your app slower
If you want to make a dropdown link clickable after user resizing screen, you can add this. This could make your app slower
----------------------------------------------------------------------------------------- */
$(window).resize(function() {
clickableDropdownLink();
})
/* ------------------------------------------------------------------------------------
This is optional
If you also want the dropdown link work in Desktop size.
----------------------------------------------------------------------------------------- */
if (window.matchMedia("(min-width: 992px)").matches) {
$('.navbar .dropdown > a').click(function() {
location.href = this.href;
});

This snippet toggles the dropdown but on click event and href is used to toggle the dropdown menu. So According to your need -
Redirect href to the general project page and add hover event to display the dropdown menu using jquery or CSS.To display the Dropdown menu just add open class to <li class="nav-item dropdown">
Using CSS,
Using Jquery
Here is my solution. The idea is to detect the area that the user clicked on the dropdown button/link and redirect to that url.
// clickable dropdown menu parent
$('.navbar .dropdown > a').on('click', function(e) {
let elementBegin = $(this).offset()['left']; // get link position X
// get the width of the menu by text's length
// you need to contain the text inside a span tag
let spanWidth = $(this).find("> span").width();
let clickAreaLength = spanWidth * 0.9; // 90% of width = clickable area
let clickPositionX = e.pageX; // position of the click
// if click position is inside the clickable area, then redirect
if (clickPositionX < elementBegin + clickAreaLength) {
location.href = this.href;
}
});
This works in the collapsed view (mobile) as well.
//Fix bootstrap dropdown parent click
let clicked = 0;
document.querySelector('.dropdown-toggle').addEventListener('click',(e)=>{
clicked++;
if(clicked > 1 && e.target.classList.contains('show')){
location.href = e.target.href
clicked = 0;
}
})
Simple javascript only solution, second click on parent will redirect to location IF dropdown contains the open class.
