CSS: how to contain absolute element inside window container - javascript

There is a way with CSS to contain absolute div inside window container ? (If div position + div width > window.innerWidth, translate div to left)
I trying to implement nav menu in 100% CSS (https://codepen.io/team/css-tricks/pen/ZYoJda) but when I have menu at the right of screen, the popup menu is split by screen.
Here is a reworked snippet:
nav > ul > li {
display: inline-block;
}
nav > ul > li ul {
visibility: hidden;
position: absolute;
top: 105%;
left: 0;
transition: 0.2s 1s;
}
nav > ul > li ul li {
width: 300px;
}
nav > ul > li:hover ul {
visibility: visible;
transition-delay: 0s;
}
nav ul {
list-style: none;
padding: 0;
margin: 0;
width: 100%;
}
nav li {
width: 100px;
background: #eee;
margin: 2px;
position: relative;
padding: 10px;
width: 15%;
}
nav a {
display: block;
}
div {
position: relative;
width: 100%;
overflow-x: hidden;
min-height: 200px;
}
body {
padding: 10px;
}
<div>
<nav>
<ul>
<li>No Menu 1</li>
<li>No Menu 2</li>
<li>Menu 3
<ul>
<li>Menu 3-1</li>
<li>Menu 3-2</li>
<li>Menu 3-3</li>
</ul>
</li>
<li>Menu 4
<ul>
<li>Menu 4-1</li>
<li>Menu 4-2</li>
<li>Menu 4-3</li>
</ul>
</li>
<li>
Menu 5
<ul>
<li>Menu 5-1</li>
<li>Menu 5-2</li>
<li>Menu 5-3</li>
</ul>
</li>
</ul>
</nav>
</div>

I found solution using JS (I would have preferred CSS).
I suppose the following structure:
<ul>
<li>Menu 1
<ul class="dropdown">
<li>Menu 1-1</li>
<li>Menu 1-2</li>
</ul>
</li>
</ul>
I implement the following JS:
const menus = document.querySelectorAll('.dropdown');
menus.forEach(menu => {
const info = menu.getBoundingClientRect();
const position = info.left + info.width;
if (position > window.innerWidth) {
// Function to update style
this.rdr.setStyle(menu, 'left', (window.innerWidth - position) + 'px');
}
});

Javascript Toggle : Hide div on click of anywhere

I have two divs. When I click on 3 dots , then the div is appearing and on clicking the same 3 dots , same div is disappearing. But I want to hide the div, even if I click anywhere in the document.
There are two circles. When I click on one circle, then a div is shown and when I click on another circle, then the opened div is closing and related div is opening but when I click anywhere on the document, then none of the div are closing.
$("#discussion_declined , #discussion_pending").click(function() {
var relatedDiv = $(this).closest('.panel').find('.discussion_edit_div');
relatedDiv.toggle("fast");
$('.discussion_edit_div').not(relatedDiv).hide('fast');
});

Praveen's answer is nice but you can also achieve the same without tweaking your HTML.
Just add this to your jQuery:
$(window).click(function() {
//Hide the menus if visible
$('.discussion_edit_div').hide('fast');
});
$("#discussion_declined , #discussion_pending").click(function(e) {
e.stopPropagation();
var relatedDiv = $(this).closest('.panel').find('.discussion_edit_div');
relatedDiv.toggle("fast");
$('.discussion_edit_div').not(relatedDiv).hide('fast');
});
And your are good to go.
This achieves one more thing which is that once you have opened one ul, then you can directly toggle to another ul by clicking once. In Praveen's answer you have to click twice in order to open the other ul.

How Bootstrap handles this is interesting. They have a mask, and the only thing you can click is the mask or the items in the menu.
$(function () {
$(".mask").hide();
$("nav > ul > li > a").click(function () {
$(this).closest("li").addClass("open");
$(".mask").show();
return false;
});
$(".mask").click(function () {
$(this).hide();
$(".open").removeClass("open");
});
});

How to hide the third nested list in this css dropdown nested lists?

I successfully created this not so bad css-only dropdown. I'm trying to hide the .submenutwo so that it is only visible when .submenu is on hover. If we can do this with css only that would be nice. But if javascript or jQuery can help it's fine.
/* define a fixed width for the entire menu */
.navigation {
min-width: 300px;
}

padding: 10px;
color: #000;
}
/* add hover behaviour */
.mainmenu a:hover {
background-color: #C5C5C5;
}
/* when hovering over a .mainmenu item,
display the submenu inside it.
we're changing the submenu's max-height from 0 to 200px;
*/

}

}
/* this is the initial state of all submenus.

.submenutwo {
display: none }
.submenu:hover .submenutwo {
display: initial }
Here's how you can do it in css. Basically, what's happening here is. At first, you just need to hide .submenutwo. After the hover triggered, you just need to bring back the display to the default or even other display value will do.
may be this will help u

Centre <li> item on click with the container set to scrolling

I have got the very nearly completed, and I just need help for the last bit.
I have a horizontal scrolling navigation, which when I click an item it brings that item into the middle of the screen (worth noting that this is for mobile screens or similiar) and gives it a class of active or something.
My problem that is that it works fine when the container div is set to overflow: hidden, however I would like the container to be free scroll by using overflow-x: scroll.
But this throw the positioning out, if you scroll across, then click on a box, you will notice that it is not centered by the amount that has been scrolled before the click.
Any help would be amazing! There is a JS Fiddle here
$(document).ready(function() {
var scrollTo = 0;
$('body').on('click', "a", function() {
var activeItem = $('li.active');
var selectedItem = $(this).parent()
var activeIndex = $('li').index(activeItem);
var selectedIndex = $('li').index(selectedItem);
scrollTo = -selectedItem.position().left + $('.container').width() / 2 - selectedItem.width() / 2;
$('ul').css('transform', 'translateX(' + scrollTo + 'px)');
activeItem.removeClass('active');
selectedItem.addClass('active');
});
});
div.container {
width: 600px;
overflow: scroll;
}
ul {
white-space: nowrap;
transition: all ease 750ms;
position: relative;
}
ul li {
display: inline-block;
background: green;
}
ul li a {
padding: 80px;
display: block;
color: white;
font-weight: bold;
text-decoration: none;
}
ul li.active {
background: blue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<ul>
<li class="active"> 1</li>
<li> 2</li>
<li> 3</li>
<li> 4</li>
<li> 5</li>
<li> 6</li>
<li> 7</li>
<li> 8</li>
</ul>
</div>
You have to take in account, the scrollLeft of the container:
$(document).ready(function() {
var scrollTo = 0;
$('body').on('click', "a", function() {
var activeItem = $('li.active');
var selectedItem = $(this).parent()
var activeIndex = $('li').index(activeItem);
var selectedIndex = $('li').index(selectedItem);
scrollTo = $('.container').scrollLeft() -selectedItem.position().left + ($('.container').width() / 2) - (selectedItem.width() / 2);
$('ul').css('transform', 'translateX(' + scrollTo + 'px)');
activeItem.removeClass('active');
selectedItem.addClass('active');
});
});
div.container {
width: 600px;
overflow: scroll;
}
ul {
white-space: nowrap;
transition: all ease 750ms;
position: relative;
}
ul li {
display: inline-block;
background: green;
}
ul li a {
padding: 80px;
display: block;
color: white;
font-weight: bold;
text-decoration: none;
}
ul li.active {
background: blue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<ul>
<li class="active"> 1</li>
<li> 2</li>
<li> 3</li>
<li> 4</li>
<li> 5</li>
<li> 6</li>
<li> 7</li>
<li> 8</li>
</ul>
</div>

Using li:hover is not showing div when the list item is an anchor

I'm having an issue with my drop down menu. I am trying to have the end result look similar to BestBuy.com's navigation. The code is below along with more explanation at the end.

width: 100%;
padding:0;
}
.navbar ul {
list-style:none;

display:inline-block;
}
.navbar ul li ul>li {
display:block;
}
.secondlevel {
position:absolute;
width:350px;
height:477px;
background:#fff;
padding:0;
border: 1px solid #c3c4c4;
}
.thirdlevel {
position:absolute;
width:350px;
height:477px;
background:lightgreen;
left:350px;
border: 1px solid #c3c4c4;
top:-1px;
}
.thirdlevel.two-columns {
width:700px;
}

display:none;
}
.secondlevel {
display:none;
}
.navbar li:hover > div:first-child {
display:block;
}
.active {
display:block;
}
The problem I'm having is that when I try to turn the list items into links with: <li><a>Products</a><li>
When I do that, hovering over the element no longer works.
Also, the hover effect doesn't work in IE either. I'm guessing that's because I'm using li:hover.
I was attempting to use jQuery for the hover effect, and I would really like to since I've read that it's better for what I need to do, but my knowledge is limited in that department.
From what I researched I could use something like this:
$(document).ready(function () {
$(".main-nav-item").hover(function () {
$(".secondary-menu").toggleClass("active");
$(".tertiary-menu").toggleClass("hide");
});
});
Of course those classes don't line up with what I have, but that's the gist of what it is. The problem I had with that was I couldn't get it to work on only one child. Hopefully that's the right word. For example: When I hovered over my first <li> it would open all of the submenus. The way it is right now is perfect, except for the fact that nothing can be a link, which is kind of important.
Let me know if you need anymore information.
Try Making the links in the <li><a>Link</a></li> in to block Elements
a { display:block; }
did the trick for me
EDIT (Went Through you Problem)
Does this what you are asking for ..
$(document).ready(function() {

$(".secondlevel").hover(function() {

Have your tried <li>EXAMPLE</li>? As for the IE side of things, I would recommend using IE specific styling or if you haven't already, used CSS Reset, for a start. Do you have a working example?

Accordion with multiple links

I'm taking this CSS-Tricks article and converting it to a UL > LI instead of a DT > DD approach. I just want the pink box to reveal the sub-links when clicked.
For some reason though I cannot get it working. I've created a jsFiddle of it here (click the pink box):
//Accordion
(function($) {
var allPanels = $('ul.sub-level').hide();
$('.click-me').click(function() {
allPanels.slideUp();
alert('slide up');
// Problem line
$(this).parent().next().slideDown();
return false;
});
})(jQuery);
ul { list-style: none; padding:0; margin:0; width: 400px; }
ul li { position:relative; background: #fafafa; margin-bottom:3px; height:20px; }
ul li > ul { margin-left: 30px; background: #e3e3e3; }
.click-me { display:block; width: 20px; height: 20px; position: absolute; top:0; right:0; background: #e4f; cursor: pointer;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>Link somewhere</li>
<li>Link somewhere</li>
<li class="test">
Link somewhere
<!-- I want to reveal accordion using this span tag -->
<span class="click-me"></span>
<!-- /end -->
<ul class="sub-level">
<li>Link 1</li>
<li>Link 2</li>
<li>Link 3</li>
<li>Link 4</li>
</ul>
<li>Link somewhere</li>
</li>
</ul>
http://jsfiddle.net/ndczc728/1/
The problem line is this (I think):
// Problem line
$(this).parent().next().slideDown();
Anyone?
You don't need to use parent. Also you have to remove fixed height from li elements:
//Accordion
(function($) {
var allPanels = $('ul.sub-level').hide();
$('.click-me').click(function() {
