Mouseenter event on parent when a child is absolute positioned - css

I'm tring to make a simple drop-down menu, which would be triggered on hover event over some element and stay active as long as the cursor is over that element or is over the dropdown list.
Sample code:
HTML
<div class="header">
<div class="items">
<div class="item">
<span>Caption</span>
</div>
<ul class="items_hidden">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
</div>
</div>
<input type="text">
CSS
.items {
float: right;
position: relative;
}
.item {
text-align: right;
}
.items_hidden {
display: none;
margin-top: 7px;
list-style: none;
z-index: 2000;
width: 80px;
border: 1px solid #f2f2f2;
text-align: left;
padding: 10px;
color: #333;
line-height: 30px;
border-bottom: 3px solid #f2f2f2;
}
input {
width: 100%;
}
JS
$(function() {
$('.items').on('mouseenter', function(e) {
$('.items_hidden').show();
});
$('.items').on('mouseleave', function(e) {
$('.items_hidden').hide();
});
});
I got that working, when the dropdown list is positioned relative, but the problem is once the list is displayed, it causes all following content to move down.
Here is an example: https://jsfiddle.net/2ya06aLo/
Another way would be to position the list absolute, so it wouldn't affect the content below. But in that case the list disappears as soons as I move the cursor out of 'Caption' (in contrast with the first fiddle).
Here is the second example https://jsfiddle.net/8L6ojqLm/
What would be a solution to make the list behave like in 1 and at the same time do not affect the rest of the content like in 2 ?

You can don't use JS
Example
.items {
float: right;
position: relative;
}
.item {
text-align: right;
padding: 10px;
}
.items_hidden {
position: absolute;
right: 0;
top: 20px;
display: none;
margin-top: 7px;
list-style: none;
z-index: 2000;
width: 80px;
border: 1px solid #f2f2f2;
text-align: left;
padding: 10px;
color: #333;
line-height: 30px;
border-bottom: 3px solid #f2f2f2;
}
input {
width: 100%;
}
.items:hover .items_hidden{
display: block;
}
<div class="header">
<div class="items">
<div class="item">
<span>Caption</span>
</div>
<ul class="items_hidden">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
</div>
</div>
<input type="text">

Couldn't it be done via pure css?
https://www.w3schools.com/howto/howto_css_dropdown.asp

Maybe this would help.
.navigation {
width: 100%;
}
.mainmenu, .submenu {
list-style: none;
padding: 0;
margin: 0;
}
.mainmenu a {
}
.mainmenu a:hover {
background-color: #D90000;
}
.mainmenu li:hover .submenu {
display: block;
max-height: 400px;
}
.submenu{
max-height: 400px;
}
.submenu a {
background-color: #FF4D4D;
}
.submenu a:hover {
background-color: #D90000;
}
.submenu{
overflow:hidden;
display:none;
}
<nav class="navigation"><!-- pocetak navigacije -->
<ul class="mainmenu">
<li>Link</li>
<li class="start">Link
<ul class="submenu">
<li>Link</li>
<li>Link</li>
<li>Link</li>
</ul>
</li>
<li>Home</li>
</ul>
</nav>

To take up the comment of CBroe: The problem seems to be the "gap" between the and the element. To remove it you could either
give the "item"-Element a height so that it "reaches down" to the ul-element or
or remove the margin-top of the ul-element

Background color won't take up whole element

I have a drop down menu button that turns grey when hovered over. However, the grey does not expand throughout the whole button, but stops at the where I set the padding.
HTML:
#dropdown {
list-style: none;
display: none;
position: absolute;
background-color: #fff;
padding: 10px;
z-index: 99999;
width: 230%;
}
#dropdown li:hover,
#dropdown li:active {
background-color: #e3e3e3;
}
#dropdown.active, #menu:target #dropdown {
display: block;
}
<ul class="main-nav js--main-nav">
<li id="menu">
Help▾
<ul id="dropdown">
<li>Give</li>
<li>Get Help</li>
<li>Get Involved</li>
</ul>
</li>
</ul>
What I want is for the grey to take up all of the drop-down menu when hovered over, as opposed to just stopping at the padding.
EDIT: I should have clarified, when I meant I want it to take up "all" of the drop down menu, I meant just the "li" when I hover over that.
Is this what you were looking for?
#dropdown {
list-style: none;
display: none;
position: absolute;
background-color: #fff;
padding: 10px;
z-index: 99999;
width: 230%;
}
#dropdown:hover {
background-color: #eee;
}
#dropdown li:hover,
#dropdown li:active {
background-color: #e3e3e3;
}
#dropdown.active, #menu:target #dropdown {
display: block;
}
<ul class="main-nav js--main-nav">
<li id="menu">
Help▾
<ul id="dropdown">
<li>Give</li>
<li>Get Help</li>
<li>Get Involved</li>
</ul>
</li>
</ul>

Hover element to effect sibling element

I have a navigation bar with a list of links and a search bar. It looks like this:
<ul>
<li class="link">Link 1</li>
<li class="link">Link 2</li>
<li class="link">Link 3</li>
<li class="link search">search</li>
</ul>
When the user hovers the "search" element, I want to
Apply a width of 500px to the hovered search elements
Apply a margin of -150px to the sibling "link" element
The CSS that I've written to do this is:
ul {
margin: 0;
padding: 0;
list-style: none;
width: 500px;
float: right;
}
.link {
width: 150px;
float: left;
line-height: 80px;
}
.search {
background: red;
width: 50px;
}
.search:hover{
width: 500px
}
.search:hover + .link {
margin-left: -150px;
}
This however has no effect on the sibling "link" elements
With pure CSS, is it possible to apply the the declarations "margin-left: -150px" on the hover of "search"?
I've created a fiddle here to illustrate the problem
https://jsfiddle.net/qut1nz9j/
If you use flex you can do like this. (Current browser support ~96%)`
The trick is you put the search link first in your markup and use order to show it last. With this you can use the sibling selector ~ to achieve what you want.
nav {
width: 700px;
background: green;
height: 80px;
float: left;
}
nav ul {
margin: 0;
padding: 0;
list-style: none;
width: 500px;
display: inline-flex;
}
.link {
width: 150px;
line-height: 80px;
order: 1;
}
.search {
background: red;
width: 50px;
order: 2;
}
.search:hover {
width: 500px
}
<nav>
<span>Site Name</span>
<ul>
<li class="link search">search</li>
<li class="link">Link 1</li>
<li class="link">Link 2</li>
<li class="link">Link 3</li>
</ul>
</nav>
Thanks to Joum, here is a nice addition to my solution: https://jsbin.com/yipujadewi/edit?css,output
If someone really need to target previous sibling and can't use flex, here is an abuse of direction: ltr/rtl in combination with display: table.
Src: CSS Tables, Invert order of displayed content
nav {
width: 700px;
background: green;
height: 80px;
float: left;
}
nav ul {
margin: 0;

list-style: none;
width: 500px;
display: inline-table;
direction: rtl;
}
.link {
width: 150px;
line-height: 80px;
display: table-cell;
direction: ltr;
text-align: left;
}
.search {
background: red;
width: 50px;
}
.search:hover {
width: 500px
}
.search:hover ~ .link {
color: #fff;
}
<nav>
<span>Site Name</span>
<ul>

<li class="link">Link 3</li>

CSS keep menu in container and expand background to full screen

The picture below shows what I would like to get.
It is a menu within a container, where the menu may wrap to multiple lines when the window/screen gets too narrow for all menu items to fit in. At the same time I would like the menu to have a background which expands to full screen in width, while expanding in height with the menu when it gets wrapped to multiple lines. Currently I think this is not possible with CSS, but I am also just a CSS amateur. My current solution involves #media queries to set the height of the menu background for resolutions where wrapping appears. This does not take into account that font-size could change, thus making each line of menu higher.
Here is a jsFiddle with a basic setup, which does NOT what I want:
https://jsfiddle.net/n3jmyq2f/3/ (Edited, was not the final version)
Here is the code:
<div class="container">
<div class="menu_wrap">
<div class="menu_bg"></div>
<div class="menu">
<ul>
<li>item 1</li>
<li>item2</li>
<li>item3</li>
<li>item4</li>
<li>item5</li>
<li>item6</li>
</ul>
</div>
</div>
<div class="content">It's me, Mario!</div>
CSS:
.container {
width:50%;
margin: 0 auto;
background:lightgreen;
height:300px;
}
.menu_bg{
position: absolute;
background: #afafaf;
width: 100%;
left:0;
height:30px;
z-index: -1;
}
ul {
height:30px;
background: #afafaf;
}
li {
display:inline-block;
}
The first option is the simplest.
Stop thinking of the .container as something that must contain everything. It's just a class that can be reused as and when required.
If you take the menu div out of the "container" but put a .container div inside you get the effect you are looking for.
JSfiddle Demo
*,
body {
padding: 0;
margin: 0;
}
.container {
width: 50%;
margin: 0 auto;
background: lightgreen;
}
.menu {
background: #afafaf;
}
ul {
border: 1px solid green;
}
li {
display: inline-block;
}
.content {
height: 300px;
}
<div class="menu">
<div class="container">
<ul>
<li>item 1
</li>
<li>item2
</li>
<li>item3
</li>
<li>item4
</li>
<li>item5
</li>
<li>item6
</li>
</ul>
</div>
</div>
<div class="container">
<div class="content">It's me, Mario!</div>
</div>
2nd Option
Use a pseudo-element
*,
body {
margin: 0;
padding: 0;
}
.container {
width: 50%;
margin: 0 auto;
background: lightgreen;
height: 300px;
}
ul {
background: #afafaf;
position: relative;
border: 1px solid green;
}
ul:before {
content: '';
position: absolute;
height: 100%;
background: inherit;
width: 100vw;
left: 50%;
transform: translateX(-50%);
z-index: -1
}
li {
display: inline-block;
}
<div class="container">
<div class="menu">
<ul>
<li>item 1
</li>
<li>item2
</li>
<li>item3
</li>
<li>item4
</li>
<li>item5
</li>
<li>item6
</li>
</ul>
</div>
<div class="content">It's me, Mario!</div>
</div>
JSfiddle Demo
if in .container you change
width:50%;
to
width:100%;
it will do it
fiddle
you could also use the .menu-wrap class (which I've seen in your markup) to do this

how to overlap a list of menus over an image

When the menu "product" is clicked or mouse over, the another list of menus appear.. but the image block which is below the menu bar, moves away from the position. if i use css [ position:absolute;], then the image box remains static and the product's sub-menu overlaps the image block, which is what i wanted. but the image blocks width & height settings change drastically, thereby spoiling the alignment.
pls chk the codings in jsFiddle
.home_menu {
border: 1px solid black;
width: 98%;

margin-right: auto;
margin-left: auto;

kindly help. My requirement is, when i mouse over the "product menu", the drop down menu should be viewed above the image block which is below the menu bar.
Add position:absolute to the css of your ul menu (in your case, the sub1 class), and remove the width:100% so it can inherit the default width of its parent. Absolute positioning will prevent your browser from trying to put your ul element after the previous element on the page.
ul.sub1 {
position:absolute;
}

CSS drop-down menus pushing page content down

This is probably (hopefully) a pretty simple question, but I can't seem to get it to work so I'll turn to the experts here. I'm using a pretty straightforward CSS drop-down menu, with just a little JQuery involved. The issue is that when I hover over the drop-down and it opens, it's pushing everything on the page down below it rather then opening over it. I've tried messing with the z-index but that doesn't seem to be the issue. Any tips would be fantastic, thanks in advance.
Here's the HTML; sorry it's not super-pretty, I had to rip out a bunch of stuff to make it simple and generic.

This is a pretty bad case of unnecessary Javascript to do what can be done via CSS itself. One way or another all you have to do is change:
#cssdropdown li.headlink ul { display: none; border-top: 1px black solid; text-align: left;}
to:
#cssdropdown li.headlink ul { display: none; border-top: 1px black solid; text-align: left;position:absolute;}
Here's an example of an extremely simple and clean drop down menu. Hope it helps you out a bit. I added a lot of comments to help you figure out what the CSS is doing to the HTML.
<style type="text/css">
/* Get ride of default margin's and padding */
ul, li {
margin: 0;
padding: 0;
}
/* Display parent unordered list items horizontally */
ul li {
float: left;
list-style: none; /* Get rid of default Browser styling */
margin-right: 10px; /* Add some space between items */
}
/* Hide inset unordered Lists */
ul li ul {
display: none;
}
/* Un-Hide inset unordered Lists when parent <li> is hovered over */
ul li:hover ul {
display: block;
position: absolute;
}
/* Clear the any element that may be "float: left;" (Essentially moves the item to the next line */
ul li:hover ul li {
clear: left;
}
</style>
<ul>
<li>
Link 1
<ul>
<li>Link 1.1</li>
<li>Link 1.2</li>
<li>Link 1.3</li>

<li>Link 3.6</li>
</ul>
</li>
</ul>
