How to create a menu tree using HTML

问题:

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.

Implementing what I learned from @sushil bharwani. Here is how I found the above URL i.e. at the courtesy of @sushil bharwani http://www.google.co.in/search?q=Menu+Tree+using+UL+L&qscrl=1

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: ", "; }

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.

回答4:

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.

回答6:

You might want to look into some of the online tools that builds the menu for you. E.g. CSS Menu Generator

回答7:

You could use JavaScript to generate the menu - for example, have a look at the plugin jQuery - Menu tree.

I am not sure if you will find your answer, but here is a list with several different types of vertical menus http://css.maxdesign.com.au/listamatic2/index.htm no javascript is involved in those examples
