I got as following:
<div parent-with-overflow-hidden>
<div absolute-position></div>
</div>
The real context is using the drop down menu bootstrap
<div overflow-hidden>
<div class="dropdown">
<button>Click to show menu</button>
<ul class="dropdown-menu">Menu</ul>
</div>
</div>
that I cannot show entire the menu.
How can I display the child div without move it outside the parent?
using position:absolute won't get it out of the parent with overflow-hidden . so you need to overwrite that with position:fixed . it will get the .dropdown-menu out of any parent/grandparent it has.
then you need to set the top position depending on the height of the parent, which is the overflow-hidden div.
after that, you need to dynamically re-calculate the top position while scrolling the page so that the dropdown stays in the same position
let me know if it works ;)
see snippet below or fiddle > jsfiddle
var oHeight = $('.ohidden ').height()
$('.dropdown-menu').css('top',oHeight)
//dropdown remain `glued` to the button on scroll
$(window).on("scroll",function(){
var wScroll = $(this).scrollTop()
$('.dropdown-menu').css('top',oHeight-wScroll)
})
.ohidden { overflow:hidden}
.dropdown-menu { position:fixed!important;}
body { height:2000px;}

I've made a sub menu list that show/hide with jquery when user hover on li list, each li shows a separate element.
Now i'm facing a problem with the jQuery code that when mouseleave, it hide the element and can't detect the hover event over this element.
The thing is, I can make it hide when switching to another list menu item and getting out of the element block. but I need it to keep showing the submenu in case the mouse is over it.
here's the code:
$(".left-nav-list-view nav ul li").mouseenter(function () {
clearMenuFlyout();
if ($(this).data('has-submenu')) {
var submenu_id = $(this).children('a').data('menu-id');
$(".flyOut-nav-container").append($("[id=" + submenu_id + "]")).position({
my: "left+1 top+0",
at: "right top",
of: this
});
}
}).on("mouseleave", function () {
});
function clearMenuFlyout(){
$(".flyout-temp-container").append($(".flyOut-nav-container").children());
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="side-nav-container flex-fixed">
<nav class="left-nav-view collapsed" role="navigation">
<div class="app-logo">
<div class="burger-menu">
<span class="burger-menu-icon"></span>
</div>
</div>
<div class="left-nav-list-view">
<nav>
<ul>
<li><span>Dashboard</span></li>
<li id="AccountingMenu" data-has-submenu="true"><a data-menu-id="AccountingMenuItems" href="#"><span>Accounting</span><i class="list-in fa fa-chevron-right"></i></a></li>
<li id="InventoryMenu" data-has-submenu="true"><a data-menu-id="InventoryMenuItems" href="#"><span>Inventory</span><i class="list-in fa fa-chevron-right"></i></a></li>
</ul>
</nav>
</div>
</nav>
</div>
basically clearFlyout function takes an already existent menu element and throw it to another div. .flyout-temp-container is hidden by default
I want append an HTML element into a DIV, but this one do not get the proper CSS like the original ones.
I have a dropdown menu, and want append on it new <li> rows.
My HTML code:
<br/><br/>
Append it
<div class="container">
<div class="row">
<div class="col-sm-3">
<h5>Normal Dropdown Button</h5>
<div class="panel panel-default">
<div class="panel-body">
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
<span data-bind="label">Select One</span> <span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu">
<div id="append">
</div>
<li>Item 1</li>
<li>Another item</li>
<li>This is a longer item that will not fit properly</li>
</ul>
</div>
</div>
</div>
</div>
</div>
</div>
<br/><br/>
My Javascript code:
$( document.body ).on( 'click', '.append', function( event ) {
$("#append").append("<li>Item 1</li>");
return false;
});
Here a live example: http://jsfiddle.net/dJDHd/2136/
EDITED WITH MY MAIN PROBLEM:
https://jsfiddle.net/Lr7gn020/1/
Click on APPEND IT, and then check the appended element by clicking on Select One button (Dropdown menu), and you will see that it do not get the proper CSS like the others (Item Test).
You've nested a div in the ul and the styles target .dropdown-menu>li>a so the div is breaking that. A div can't be a direct child of a ul and li can't be a direct child of a div. Instead of nesting a div in the ul, then appending li's to the div, you can $.prepend() li's directly to the menu, if you want them to appear at the beginning of the menu when you add them. If you don't care where they appear, you can $.append() them to the bottom instead.
$(document.body).on('click', '.append', function(event) {
$(".dropdown-menu").prepend("<li>Item Test</li>");
return false;
});
.btn-input {
display: block;
}
.btn-input .btn.form-control {
text-align: left;
}
.btn-input .btn.form-control span:first-child {
left: 10px;
overflow: hidden;
position: absolute;
right: 25px;
}
.btn-input .btn.form-control .caret {
margin-top: -1px;
position: absolute;
right: 10px;
top: 50%;
}

The reason behind the appended option having different css is due to the fact that you are appending it inside a div element.
The current CSS of the li elements comes from the bootstrap css with this selector.
dropdown-menu>li>a
Since you have a div node inside ul (which is wrong and make html invalid) and you are appending a new li inside this div with JS, the above selector will not reach this node and CSS will not be applied.
You should add the li node directly under the ul node.
Fiddle : http://jsfiddle.net/9med3Lou/
Change your jquery part.
$( document.body ).on( 'click', '.append', function( event ) {
$(".dropdown-menu").append("<li>Item 1</li>"); //append with ul, not div
return false;
});
I'm trying to get my responsive navigation to collapse when clicking a navigation item (link).
This is my navigation:
<nav class="nav">
<ul>
<li class="nav-item">Overview</li>
<li class="nav-item">Amenities</li>
<li class="nav-item">Residences</li>
<li class="nav-item">Neighborhood</li>
<li class="nav-item">Availability</li>
<li class="nav-item">Contact</li>
<li class="btn login">Login</li>
<li class="nav-toggle"></li>
</ul>
</nav>
Here's how the responsive nav gets expanded:
<script>
function myFunction() {
document.getElementsByClassName("nav")[0].classList.toggle("responsive");
}
</script>
I'm not sure why you're mixing old school list tags with the modern Nav because you don't need them.
If you want the menu to collapse upon selection you can use this neat technique:
<nav style="position:absolute; left:20px; top:50px;">
<div onclick="TheBox.removeAttribute('open');">
<details id="TheBox"><summary>Choices</summary>
Home<br>
About<br>
Products<br>
Services<br>
Contact
</div></details></nav>
It looks like you want to hide the navigation when the toggle link is clicked. If so, I would do the following. Note that your <a> tags were outside the <li> tags, I've moved them inside.
<nav id="nav">
<ul>
<li class="nav-item">Overview</li>
<li class="nav-item">Amenities</li>
<li class="nav-item">Residences</li>
<li class="nav-item">Neighborhood</li>
<li class="nav-item">Availability</li>
<li class="nav-item">Contact</li>
<li class="btn login">Login</li>
<li class="nav0item">Toggle</li>
</ul>
</nav>
I would target by ID and not class, and set the display to none.
<script type="text/javascript">
function collapseNav() {
document.getElementById('nav').style.display = "none";}
</script>
Since your toggle is on a <li> inside the nav, your navigation menu (and the toggle) will be hidden when activated. So, I'd make a way to show it again. You could, for instance, add this function in your JS.
function showNav() {
document.getElementById('nav').style.display = "block";}
And then add a link somewhere for the user to show the menu again.
<button onclick="showNav();" >Show Menu</button>
If you go that route, I'd also hide the Show Menu button by default by adding id="shownav" style="display: none;" to hide it initially. And then have your collapseNav function also show the button:
document.getElementById('shownav').style.display = "block";
Thank you for your responses.
This is what I was looking for:
$(document).ready(function(){
$("li.nav-item a, .logo").click(function(){
$("nav").removeClass("responsive");
});
});
Now the "responsive" class gets removed when clicking on a navigation item or the logo, so my navigation returns to collapsed mode.
I am hoping somebody can help me out with my Javascript. The JSFiddle shows you how far I have got, I'm not far off...but I am basically trying to get the content of the enclosed DIVs to align to the top of the '.news_window' box when the nav is clicked.
http://jsfiddle.net/s5sxa0sk/2/
I realise that the scrollTop going to 'this' is incorrect, but I don't know how else to proceed.
Any input would be very much appreciated.
The HTML:
<ul class="news_archive">
<li class="active">December</li>
<li>November</li>
<li>October</li>
</ul>
<div class="news_window">
<div id="dec_2014">
<p>December Content</p>
</div>
<div id="nov_2014">
<p>November Content</p>
</div>
<div id="oct_2014">
<p>October Content</p>
</div>
</div>
The Javascript:
<script>
$(".news_archive li").click(function(e){
e.preventDefault();
$('.news_window').animate({scrollTop:$(this).position().top}, 'slow');
$('.news_archive li.active').removeClass('active');
$(this).addClass('active');
});
</script>
Your main issues is you're using the #new_archive link's top position to animate the scroll instead of the #news_window item's top position. You need to find the #news_window element based on which link is clicked and use that element's position().top.
You will also need a wrapper around the #news_window items otherwise each element's position().top will change based on the current scroll position of the #news_window element. This wrapper will need position: relative set.
Here's what I mean:
<ul class="news_archive">
<li class="active">
<a data-id="dec_2014" href="#">December</a>
</li>
<li>
<a data-id="nov_2014" href="#">November</a>
</li>
<li>
<a data-id="oct_2014" href="#">October</a>
</li>
</ul>
<div class="news_window">
<div class="wrapper">
<div id="dec_2014">
<p>December Content</p>
</div>
<div id="nov_2014">
<p>November Content</p>
</div>
<div id="oct_2014">
<p>October Content</p>
</div>
</div>
</div>
And the Javascript:
$('.news_archive li a').click(function(e) {
e.preventDefault();
var newsWindowEl = $('#'+$(this).data('id'));
$('.news_window').animate({
scrollTop: newsWindowEl.position().top
}, 'slow');
$('.news_archive li.active').removeClass('active');
$(this).parents('li').addClass('active');
});
Here's a working version of your fiddle: http://jsfiddle.net/s5sxa0sk/42/
Whenever I hover over the second button in the menu, a "submenu" appears. When it appears, it partially covers the images in a div "container".
The styling of the submenu is such that it is semi-transparent so the images inside the div "container" also appear in the background of the menu, which doesnt look that good.
I know that the simple solution would be to change the location of the div but then the images would not be centered so that is not an option. I was wondering if it is possible that whenever I hover over the buttons that have a submenu, the div "container" hide and appear again when I move my mouse away from the menu. The div "container" should not hide when hovering over first Home button since it does not have a submenu and images should remain hidden as long as the menu is open. Is it possible in javascript or jQuery or CSS3??
HTML Code:
<div id="menu">
<ul class="menu" id="tempMenu">
<li class="Home">Home</li>
<li class="HOme2"><a id="secondElement" href="www.google.com">Home2</a><div>
<ul class="submenu">
<li>
<a id="one" href="">One</a>
</li></br>
<li>
<a id="two" href="">two</a>
</li>
<li>
<a id="three" href="">three</a>
</li>
<li>
<a id="four" href="">four</a>
</li>
<li>
<a id="five" href="">five</a>
</li>
<li>
<a id="six" href="">six</a>
</li>
<li>
<a id="seven" href="">seven</a>
</li>
<li>
<a id="eight" href="">eight</a>
</li>
</ul>
</div>
</li>
</ul>
</div>
<div id="container">
<div id="box1" class="box">Image1<img src="images/image1.png"></div>
<div id="box2" class="box">Image2<img src="images/image2.png"></div>
</div>
CSS Code:
ul.menu .submenu{
display: none;
position: absolute;
}
ul.menu li:hover .submenu{
display: block;
}
$('.submenu').hover(function() {
$('#container').hide()
}, function() {
$('#container').show()
});
You basically want to detect on the hover event whenever the current menu item (one of the .menu > a elements) contains a submenu (.submenu).
What about :
$('.menu > a').hover(function(){
if ($(this).find('.submenu').length != 0) {
$('#container').hide();
}
}, function(){
$('#container').show();
});
Also, some of your html closing tags have issues, you should ensure that they are all closing in a correct order to prevent unexpected glitches.
firstly give that div 2 class names like-class1,class2
in Css :
.class1{
display: none;
position: absolute;
}
.class2{
display : block;
}
in jquery :
//this would track mouse pointer in/out events
$("#menu").hover( function(event){ $("#div").attr("class","class1"); },
function(event){ $("#div").attr("class","class1"); } );
You forgot to close this
<li class="HOme2"><a id="secondElement" href="www.google.com">Home2</a><div>
to
<li class="HOme2"><a id="secondElement" href="www.google.com">Home2</a></li><div>
for the Jquery i think this will help
$('.submenu').mouseenter(function() {
$('#container').hide()
}).mouseleave(function(){
$('#container').show()
});
