Keep submenu while moving mouse - javascript

I want to make a menu (with submenu and div containing link for every submenu on hover).
Something like this:
AAAA | BBBB
| bbb1
| bbb2 HERE IS MOUSE (bbb2 LINK)
| bbb3
It is possible to keep listing submenus when you try to open link? If you move mouse from "bbb2" link disappear.

Here is JSFiddle: http://jsfiddle.net/zu8Eu/
Hope you understand. Thanks!

As is noted you may need to nested the <div> inside the li elements. But additional to keep the hover() you can use padding to set the white space:
HTML
<li id="submenu1">
aaaa1
<div class="one">
Link for aaa1
</div>
</li>
CSS
.one {
display: none;
position: absolute;
top: 0px;
left:100%;
}
The demo http://jsfiddle.net/zu8Eu/27/

I'm sure the are jQuery plugins that will provide you with what you want to achieve, but I'd say restructure you HTML and nest the elements properly.
<ul>
<li>Menu 1
<ul>
<li>
Submenu 1
<ul>
<li>
Subsub menu
</li>
</ul>
</li>
</ul>
</li>
</ul>
This way, you can use CSS to achieve what you want:
ul li ul{
display: none;
}
ul li:hover > ul{
display: block;
}
ul li ul li:hover > ul{
display: block;
}
Once you hover on the first li, it will show the direct child ul, if you hover on that ul, it will still count as a hover on the first li, meaning it'll still be visible.

if or case Statement in css

I'd like some help writing or finding out if it's possible to write an if or case statement in css for a hover function. The hover is for a dropdown that reveals links with shared class parent names.
The essential logic is, if one class's hover function is activated/on, deactivate/turn off the other hover function within the that share the parent class.
in my mind the psuedocode looks like this:
if (.drop: hover .last) /*when the cursor hovers, do below*/ then
.drop: hover .last{display:block;}
.drop:hover .first{display: none;}
.drop:hover .second{display: none;}
.drop:hover .third{display: none;}
etc...
elseif (.drop:hover .first) then
.drop:hover .first{display: block;}
.drop:hover .last{display: none;}
.drop:hover .second{display: none;}
.drop:hover .third{display: none;}
endif
If I understand what you mean, you need use :not to ignore a li:hover.
Note: use opacity instead display: none because the second one move the li to left and lost :hover.
Look the code below:
HTML
<ul>
<li>Link 1</li>
<li>Link 2</li>
<li>Link 3</li>
</ul>
CSS
ul {
display: inline-block;
}
ul > li {
display: inline-block;
padding: 5px 15px;
}
ul:hover > li:not(:hover) {
opacity: 0;
}

Jquery: Navigating in menu using tab

I want to find a general rule that will help me navigate in menus, using tab. I know how to catch the tab event but there are several problems:
There are drop-down menus that i can't accese only be pressing tab key.
The structure of the drop-down menus is not standard. i.e. the hidden ul elements may be inside other elements (e.g div) or may be nested drop-down menus inside other drop-down menus
The events that make the hidden menus to be visible/invisible vary. Click and hover events are the most popular.
Can someone help me?
You can use the tabindex attribute on the list item that triggers the showing of your dropdown. This wil make the parent li focusable by pressing tab. You can then, with some CSS and Javascript, apply rules to children to make them visible.
About the fiddle:
Note that I use the opacity and pointer-events properties in CSS to switch states of the dropdown. When an element has visibility: hidden or display: none applied, it will not be focusable at all. Since the tab key by default brings focus to the next focusable element, your target element should not have either of those properties set to the shown values at the point the tab key is being pressed.
Also, you'll have to accurately keep track of the tabindexes throughout your navigation. First is the first main anchor, then the enclosing list-item, to make the dropdown visible. Then come the anchors inside that. (this is the point where JS has to take over from CSS) This brings us at tabindex 5 when the 3 subItems inside are assigned a tabindex, so we'll continue counting from 6 for the next main item's direct <a> child, and so forth.
You'll have to figure out the way to make your multi-level dropdowns work as expected yourself, but this is a starting point. You could additionally check in your script for arrow key presses, and give another element focus in response.
Fiddle:
$(function() {
$('nav').on('focus', '.dropdown a', function() {
$(this).closest('.mainItem').addClass('focus');
}).on('blur', '.dropdown a', function() {
$(this).closest('.mainItem').removeClass('focus');
});
});
nav > ul {
display: flex;
}
nav ul {
list-style: none;
margin: 0;
padding: 0;
}
nav .mainItem {
position: relative;
margin: 0 5px;
padding: 0.5rem;
background-color: #eee;
}
nav .dropdown {
position: absolute;
width: 100%;
left: 0;
top: 100%;
opacity: 0;
pointer-events: none;
}
nav .mainItem:hover .dropdown,
nav .mainItem:focus .dropdown,
nav .mainItem.focus .dropdown,
nav .mainItem > a:hover .dropdown,
nav .mainItem > a:focus .dropdown
nav .mainItem.focus .dropdown {
opacity: 1;
pointer-events: all;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<nav>
<ul>
<li class="mainItem" tabindex="2">Parent 1
<ul class="dropdown">
<li>Child 1</li>
<li>Child 2</li>
<li>Child 3</li>
</ul>
</li>
<li class="mainItem" tabindex="7">Parent 2
<ul class="dropdown">
<li>Child 1</li>
<li>Child 2</li>
<li>Child 3</li>
</ul>
</li>
</ul>
</nav>

CSS li dropdown on touch devices

EDIT: Thanks for the answers. Do these suggestions keep the li:hover dropdown working, just adding the onclick feature for touch devices? I don't want desktop users to have to click, the menu should appear on:hover for them.
I have done my research on this subject but can't seem to find a good solution.
My site http://www.eastbournenl.com
Menu's in question are 'League Info' and 'Results' in the top navigation bar.
My CSS dropdown menu activates on li:hover (the li item is NOT a link, I changed the cursor so it appears as a hand but clicking will take you nowhere).
However, clearly this doesn't work on touch devices.
Is there a way to maintain the setup I have currently with the li:hover working on non-touch devices, but adding some javascript to enable functionality for touchscreen devices?
HTML
<div id="link_bar">
<ul>
<li>League Info
<ul class="drop">
<li>Team Directory</li>
<li>Fixtures</li>
<li>Rules</li>
<li>Umpire Directory</li>
</ul>
</li>
</ul>
</div>
And CSS
#link_bar ul ul {
display: none
}
#link_bar ul li:hover > ul {
display: block
}
#link_bar ul:after {
content: "";
clear:both;
display:block
}
#link_bar ul ul {
position: absolute;
top: 1em;
width: 10em;
padding-top: 1em;
margin-left: 0;
}
#link_bar ul ul li {float:none ; position: relative ; padding: 1em 1em 1em 0}
#link_bar ul ul li {width:100%}
#link_bar .drop li:hover a {color: #99FF33}
With Modernizr, you can target touch devices, so include it in your code, and then :
JS part :
if(Modernizr.touch){
$('.hasDropDown').click(function(){
$(this).find('.drop').addClass('visible');
});
}
HTML part :
<div id="link_bar">
<ul>
<li class="hasDropDown">League Info
<ul class="drop">
<li>Team Directory</li>
<li>Fixtures</li>
<li>Rules</li>
<li>Umpire Directory</li>
</ul>
</li>
</ul>
</div>
CSS :
.visible {
display: block;
}
That's weird, most of touch devices emulate hover events.
as you know touch device not supported hover effects
you can use some plugin for that,like Modernizer.js
another solution i see on the Web is:
div#menu ul li:hover ul needs to become div#menu ul li:active ul for it to respond on touch devices because they don't support hover states.
my specific solution for you is:

Jquery - dropdown menu on click

I am relatively new to jquery and I am seeking help. The aim is to click on a list item attached to a ul and have it appear whilst any other list items disappear. Only the active one is viewable
The Issue I am having is that when I click on another list item the active one disappears (as intended), but it doesn't reveal the other one, it remains hidden. I am looking for a way to reveal the list, while hiding the ones that are in-active.
I have uploaded my problem: http://jsfiddle.net/CbU4d/
html:
<div id="secondary-nav"><!--secondary-nav-->
<ul>
<li>Current Article
<ul>
<li>Example 1</li>
</ul>
</li>
<li class="active">Past Articles
<ul>
<li>Example 1</li>
<li>Example 2</li>
<li>Example 3</li>
</ul>
</li>
</ul>
</div><!--/secondary-nav-->
css:
#secondary-nav {
float:left;
height:auto;
width:23%; /*210px*/
border-right:2px solid #000;
position:relative;
}
/*heading styles*/
#secondary-nav ul li {
padding: 0 10px;
list-style-type: none;
}
#secondary-nav ul li a {
font-family:TrajanPro;
font-size:1em;
line-height: 32px;
color:#000;
}
/*links*/
#secondary-nav ul ul li a {
display: block;
font-family:TrajanPro;
font-size:0.9em;
line-height: 27px;
text-decoration: none;
color:#000;
transition: all 0.15s;
}
#secondary-nav ul li a:hover {
display:block;
color:#af2931;
text-decoration:underline;
}
#secondary-nav ul ul {
display: none;
}
#secondary-nav li.active ul {
display: block;
}
/css
jquery using 1.7.1
$(document).ready(function(){
$("#secondary-nav ul").click(function(){
//slide up all the link lists
$("#secondary-nav ul ul").slideUp();
//slide down the link list below the h3 clicked - only if its closed
if(!$(this).next().is(":visible"))
{
$(this).next().slideDown();
}
})
})
Try with
$("#secondary-nav ul ul").slideToggle();
Demo
I got it to work (I think) by making two changes:
Change the selector on line 2 to this:
"#secondary-nav ul li"
This means the event will be attached to the list item you click, not the entire list.
Remove the if statement on line 6. Since we're hiding all of the second level uls in the previous line, we don't need to check if it's visible; we know it isn't.
Change line 6 to this:
$(this).children('ul').slideDown();
This is because the ul you want to unfold is a child of the li you're clicking, not a sibling.
Here's my fixed jsFiddle.
Edit: If you want to stop it from hiding and re-showing when you click the one that's already expanded, just chuck this at the top of the handler:
if ($(this).children('ul').is(':visible')){
return
}

CSS single select list example

I am looking for a click based single select list. Instead of the normal drop down list, I want an overlay menu (similar to how we see on facebook when we change privacy settings, the single select list that appears). Is that CSS based or any code examples to creating a similar list? All the lists i found of the net are hover lists not same as we see on f/b.
Thanks.
Something like this:
It is just a menu that pops up where use can pick an option.
If you were using jQuery it would be something like this plug-in
http://plugins.jquery.com/project/selectbox
I can't find a non JS-solution (and for JS I'm using jQuery to assign focus to an arbitrary element that would keep the sub-menu open (on the plus side, I'm pretty darn sure that Facebook will be using JavaScript, of some sort, to achieve their implementation too).
However, I've put together a couple of examples, these are, much like Facebook, simply dropdown lists, with a JavaScript handler to assign focus to the clicked element (to keep the sub-menu open regardless of mouse position on the page, until the user clicks elsewhere).
With that in mind, I've used the standard css dropdown-style mark-up:
<ul>
<li>Symbol
<ul>
<li>option 1</li>
<li>option 2</li>
<li>option 3</li>
</ul>
</li>
<li>Symbol
<ul>
<li>option 1</li>
<li>option 2</li>
<li>option 3</li>
</ul>
</li>
<li>Symbol
<ul>
<li>option 1</li>
<li>option 2</li>
<li>option 3</li>
</ul>
</li>
</ul>
With the css:
ul {
list-style-type: none;
padding: 0;
margin: 0 auto;
}
ul li {
display: inline-block;
position: relative;
width: 100px;
border-bottom: 1px solid #ccc;
}
ul li ul {
display: none;
width: 100%;
position: absolute;
top: 1em;
left: 0;
}
ul li a:hover + ul,
ul li a:active + ul,
ul li a:focus + ul {
display: block;
}
ul li ul li {
border: 0 none transparent;
}
And the jQuery:
$(document).ready(
function() {
$('li a').click(
function(){
$(this).focus();
});
}
);
Demo at JS Bin
Notice that I've used a elements, since focus is more easily assigned to anchors than plain, in this case, li elements. However a second version, with the same end result is achieved with the following jQuery:
$(document).ready(
function() {
$('li').click(
function(){
$('li').not(this).removeAttr('tabindex');
$(this).attr('tabindex','-1').focus();
});
}
);
Demo at JS Bin.
Addenda
Stu Nicholls, of CSS Play seems to have achieved a pure-css solution for this (with a gallery), but I haven't worked my way through his CSS to see how he did it.
