I need to create a menu tree using HTML. I had a search on Google, but they are providing some software to download in order to create this. But I need some script and HTML tags to do this.
Can anyone help me solve this problem.
Thanks in advance.
Here is something very simple to start with.

You don't need to use JavaScript (unless you want compatibility with outdated browsers), you can achieve it with HTML+CSS alone. And in a much more semantically-correct way. :)
You can make vertical dropdown menus or (prettier example) horizontal menus using the techniques explained in the Sons of Suckerfish article at HTMLDog.
Simple and meaningful.
Sample
Here is a simple example. In it you can see the hover functionality working perfectly.
The CSS is not good, because it's only a sample.
To work on the style, disable the display: none; line: that will stop the submenus from hiding when not hovered, and you can work on styling everything.
When you are done, simply re-enable the display: none; line to get the submenus to hide and only show on hover.
HTML
<nav>
<p>Collapsing:</p>
<ul class="collapsable">
<li>a<ul>
<li>a1
<li>a2
</ul>
<li>b<ul>
<li>b1
</ul>
</ul>
<p>Not collapsing:</p>
<ul>
<li>a<ul>
<li>a1
<li>a2
</ul>
<li>b<ul>
<li>b1
</ul>
</ul>
</nav>
CSS
nav li:hover {
background: #EEEEEE;
}
nav li>ul {
display: inline-block;
margin: 0;
padding: 0;
}
nav .collapsable li>ul {
display: none;
}
nav li>ul::before {
content: ": { ";
}
nav li>ul::after {
content: " } ";
}
nav li:hover>ul {
display: inline-block;
}
nav li>ul>li {
display: inline-block;
}
nav li>ul>li+li::before {
content: ", ";
}
Here is a jsfiddle: http://jsfiddle.net/x8dxv/
With a bit of javascript and a knowledge around CSS you can convert a simple UL LI list to a menu tree. its right that you can use jQuery if you understand it.
You can narrow your google search by Menu Tree using UL Li. or CSS to convert UL LI to tree.
Navigation menus are mostly created using a combination of UL and LI.
<UL id="Menu">
<LI>Home</LI>
<LI>Links</LI>
</UL>
And you can insert UL inside LI element and thus get a tree structure for navigation.
Here is a simply way to do it if you don't want to write one yourself..

You might want to look into some of the online tools that builds the menu for you. E.g. CSS Menu Generator
I am not sure if you will find your answer, but here is a list with several different types of vertical menus

no javascript is involved in those examples

I'm developing a navigation bar for a site that needs ie7>= support. The nav bar can contain any amount of links, and each link can contain different amounts of text, and so can be different sizes. However I'd like the nav bar to automatically space each link out so that they fill the parent container.
Here's a solution using pure css to set the padding on each nav bar:
https://jsfiddle.net/n07x8963/4/
#nav_1 li { padding:0px 36px;}
The trouble is this requires padding to be manually specified for each nav bar depending on how many links there are and the width of the text within the links. This has to be done every time the content of the nav bar changes.
A way of doing this automatically is of course to use tables:
https://jsfiddle.net/t0t29yne/1/
Or by JavaScript as seen here:
https://jsfiddle.net/jtz4thfo/1/
Each of the solutions have advantages / disadvantages, so I'd like to know if anyone has a better solution, or an argument towards using any of the mentioned methods.
Thanks
UPDATE:
I've ended up opting for tables, ie7+ browsers get served UL's, LI's with display:table-row, display:table-cell overridden in the CSS.
Where as ie7 get's served actual tables.
I know using Tables for layout is generally seen as wrong, but in this case there is no adequate pure CSS solution so I think it's the best / easiest solution.
In IE7 i suggest using tables for only via CSS will not be possible.
.nav {
width: 600px;
height: 20px;
background-color: #FF9;
}
ul {
list-style-type: none;
padding: 0;
margin: 0;
display: table; /*IE8+ and non-IE*/
width: 100%;
}
ul li {
background-color: #F9F;
display: table-cell; /*IE8+ and non-IE*/
text-align: center;
}
<div id="nav_1" class="nav">
<ul>
<li id="link_1">AAAA</li>
<li id="link_2">BB</li>
<li id="link_3">CCCCCC</li>
<li id="link_4">DDDD</li>
<li id="link_5" class="last">EEEEEE</li>
</ul>
</div>
<div id="nav_2" class="nav">
<ul>
<li id="link_6">FFFFFF</li>
<li id="link_7">GGGG</li>
<li id="link_8">HH</li>
<li id="link_9">IIIIIII</li>
<li id="link_10" class="last">JJJJ</li>
</ul>
</div>
Okay...I know there are already loads of Pure CSS Tab Controls out there...
Here is my HTML
<div class="tabs">
<ul>
<li>One</li>
<li>Two</li>
<li>Three</li>
</ul>
<div id="tabPage1">
<p>
Hello World
</p>
</div>
<div id="tabPage2">
<p>
Goodbye World
</p>
</div>
<div id="tabPage3">
<p>
Another World, somewhere far, far away!
</p>
</div>
</div>
Here is my CSS
.tabs > div {
display: none;
}
.tabs > div:target {
display: block;
}
There's no styling for this example as I'm only concerned with the behavior.
You can try it here...http://jsfiddle.net/rcrdC/
How do I get it to display the first div until an anchor is clicked?
How do I get it to leave the displayed div...displayed, even when I change the anchor to something else (i.e. #tabPage4)...if that makes sense?
from here , you can make the last one be display at the beginning with like this (working example)
.tabs > div:target ~ div:last-child,
.tabs > div{
display: none;
}
.tabs div:last-of-type,
.tabs > div:target {
display: block;
}
Just move the first tabpage to be the last.
This is an interesting challenge. Unfortunately, I don't believe the intended result can be achieved (purely) with CSS.
We can show the first div easily enough using:
div:first-of-type { display: block; }
But I don't know of a way to select our previously :targeted divs without using JavaScript.
Here I've set up some jQuery to apply class .active on any div with an id that equals that of a clicked anchor href. From there we can override display: none; on divs of that class with some simple CSS:
$('li a').each(function () {
$(this).click(function () {
var active = $(this).attr('href');
$(active).addClass('active');
});
});
And here's the related CSS:
div:first-of-type, div:target { display: block; }
div { display: none; }
.active { display: block; }
And a working example: http://jsfiddle.net/fjKUw/1/
showing the first tab on load should not be that hard. You can use the :first-of-type pseudo class. Something like this:
.tabs > div{
display: none;
}
.tabs > div:first-of-type,
.tabs > div:target {
display: block;
}
The second question is a bit harder. The first tab will be shown again as soon as your target moves to an anchor outside the tabs. http://jsfiddle.net/rcrdC/4/ You need some way to preserve state. The 'real life' solution would be to add a few lines of javascript to achieve this, as suggested already by #StuartKershaw.
If you insist on going fully css, you could use a (hidden) radio button to preserve the state. It is a bit hacky (inputs are not meant for that) and you would have to change your markup a bit, but it should be feasible.
An example of what I mean can be found here: http://jsfiddle.net/rcrdC/5/
Note that I placed some hidden radio buttons between the tabs. I replaced the links to the tabs by labels that reference those radio's. Then I use a combination of the :checked and the + selector to make things work. And the tab that is visible on load is the one with checked attribute.
Again, this is not the way I would recommend. You are adding to your markup, with the sole purpose of achieving a certain layout, which should be the task of your css. Also the stuff you need to add is far from semantically correct...
I've written this code to create simple CSS and Javascript dropdown menu.
HTML:
<li>XYZ
<ul id="rankSubMenu" onmouseover="showRanksSubmenu()" onmouseout="hideRanksSubmenu()">
<li>AAA</li>
<li>BBB</li>
<li>CCC</li>
</ul>
</li>
CSS:
#rankSubMenu {
display: none;
position: absolute;
bottom: 10px;
left: 278px;
}
JS:
function showRanksSubmenu() {
document.getElementById('rankSubMenu').style.display = 'block';
}
function hideRanksSubmenu() {
document.getElementById('rankSubMenu').style.display = 'none';
}
Menu items have of course some height, background and other stuff to make them look like buttons. The problem is that, there is some empty space between this buttons (like a few pixels) and when user stops mouse cursor there, menu disappear (in fact menu always does that, unless you move your cursor real fast). I tried to define this whole area as div or try any other ideas that I thought about, but with no success. Any suggestions how can I solve this?
First off, welcome to the wonderful world of web development. Based on your use of inline styles, li as a top-level container, and attempted use of Javascript for a simple menu show/hide I can tell you're pretty new. No matter! Its a learning process, and web development is fun. :)
First, for what you want, you can do this via CSS only, and without the need for position:absolute in your menu items or anything crazy like that. Here is a working example of a cleaner menu display:
jsFiddle example
My recommendations for the learning process:
Get comfortable with external CSS sheets, use of inline styles is pretty ancient, and very difficult to maintain
Learn about the benefits of classes over IDs when styling; rarely (never?) do you need to use IDs for styling, and class is usually preferred because you can apply it to multiple elements
Get familiar with proper semantic markup; for example li should not be a top-level container, only the container of another ul if there is a sub list or something
Learn external JS event handlers; using inline onwhatever handlers in HTML is another pretty ancient method, and again makes maintenance very difficult
Best of luck!
CSS
.dropdown li{
float:left;
width: 240px;
position:relative;
}
.dropdown ol{
position:absolute;
left:-9999px; /* Hide off-screen when not needed (this is more accessible than
display:none;) */
}
.dropdown li:hover ol{ /* Display the dropdown on hover */
left:0; /* Bring back on-screen when needed */
}
HTML
<ul class="dropdown">
<li>
<a href="#" >Your Link</a>
<ol>
<li> Your Link 1 </li>
<li> Your Link 2 </li>
</ol>
</li></ul>
What else would u need for this? Is there any reason to use javascript to create this?
Take a look at this Fiddle. Perhaps it's what you're looking for.
it's only using HTML and CSS.
#rankSubMenu is probably 0px high, try to add some height, also you can do this js free by using :hover
My guess would be set your anchor tags to display block. If an anchor tag is not a block it will ignore a few css properties, width and height being the two main ones, so your click is just the text.
another possible reason is that the submenu coming in is partially covering the link (check your inspector to see what area it's covering).
if you set the height to that of the original item with overflow hidden and then on hover set height to auto
HTML
<nav class="navigation">
<ul>
<li>Menu</li>
<li>Home</li>
<li>About</li>
</ul>
</nav>
CSS
.navigation {
height: 20px;
overflow: hidden;
}
.navigation {
height: auto;
}
no javascript needed

I'd like to click the About button to go to the About page. I'm using Javascript and JQuery to handle the behavior (make the whole li clickable). For some reason, clicking about in different areas of the li doesn't always load the page.
I'm open to not using jQuery if there's a better solution.
The "contact information" and "hobby projects" li don't have an href, so the links don't work. If you go to the About page, the menu works based on CSS without the javascript trying to make the whole li clickable. So there is no javascript on the about.html page, and you can see the menu problem without any javascript.
Thanks for your help!
index.html
<div class="navcontainer">
<ul><li>Link Title</
li><li>Second_Link Title</ <!-- fixes extra space with </li><li> -->
li></ul>
</div>
style.css
#nav li
{
display: inline-block;
List-Style-Type: None;
float:left;
text-align:Center;
width: 153px;
height:46px;
font-size: 80%;
border-Bottom: 1px solid #666666;
}
#nav li #about
{
z-index: 10000;
position: relative;
top: 18px;
text-decoration: underline;
-moz-user-select: -moz-none;
-khtml-user-select: none;
-webkit-user-select: none;
}
just add the following in your CSS:
#nav li.about a{
z-index:10000; }
and it will work
Your issue is not the javascript, but the CSS. You have a hover attribute that enlarges the <li>. When you click, the active attribute causes it to shrink, making the element smaller than it previously was. If you click in the upper corners of the enlarged element, it won't load because the element is now below the clickable area. If you click in the middle towards the bottom, it will.
Ultimately, for something like this, you might be better off using jQuery UI to manage your tabs or use Twitter Bootstrap. Out of the box it works, and you don't have to worry about CSS issues, plus they already look nice so no extra styling.
If you want to stick with you already have going, you may just want to ditch the fancy CSS. Get rid of the :active class and it should work okay I think.
The problem you have right now is that the li is bigger then the a. Clicking on the li, but outside the a will not make the link work, as you already found out.
In stead of applying all your styles and effects to the li element, you should apply them to the a element directly and set it to display as a block. This way the li will take the same size as the a, and whereever you click on the hovered item, your href will work just fine. Bigger links is always a good idea, definitly with the amount of tablets and other toutchscreen devices rizing every day.
Note that it will not be a straight copy / paste of your code, especially when it comes to floats and positioning, but it should not be to hard to achieve what you are after by applying the styles directly to the a element. If you have difficulty converting your code, feel free to set up a working example on jsfiddle and we will be happy to help out where possible.
This solution does not require any js what so ever. Using js for your main navigation is always a bad idea, as it will make it hard, if not impossible, to navigate your site for people with js disabled. Not exactly what i would call gracefull degrading...
I have a pure css/html dropdown menu, the code for which I pretty much stole from csswizardry here. It works like a charm; the only problem is that, if that menu item is on the far right side of the page, the dropdown items are half-off the page.
I'm working on a javascript solution; is there a way to fix this problem using just CSS?
EDIT: I'm looking for the dropdown content to move to the left so that the dropdown items are fully visible.
Looking at the code you based it on, instead of
#nav li:hover ul { left:0; }
...you'd want:
#nav li:hover ul { left:auto; right:0; }
Looks like you may need to adjust the right margin of #nav li if you're using the same CSS as csswizardry.
