Sometimes in our project we need to add menus
and submenus...so instead of writing long javascript
code(if you are a damm good javascript programmer) or
Scritping code,ts far better to use YAHOO User interface tool...
It contains lots of many useful tools and reduce rather saves
our time a lot..so the first example of YUI that i gonna share with
u all is the Treeview Menu...
Its very simple..just follow the steps or instruction given below
- Copy the YUI folder to your root directory..You can download it from http://developer.yahoo.com/yui/
- Now open the page in which you want to add this tool..
like i hv added this tool in a CMS in which many sub links were there.. - Add the code in header section of ur page
<link rel='stylesheet' type='text/css'
href='../yui/build/fonts/fonts-min.css' />
<link rel="stylesheet" type="text/css"
href="../yui/build/treeview/assets/skins/sam/treeview.css"/>
<script type="text/javascript"
src="../yui/build/yahoo/yahoo-min.js"/></script/>
<script type="text/javascript"
src="../yui/build/event/event-min.js"/></script/>
<script type="text/javascript"
src="../yui/build/treeview/treeview-min.js"/></script/>
<style/> #treeDiv1 {background: #E4DDC0; padding:1em;} </style/> - Add below given line at the place where you want the tree..
Like in my case i have placed the tree in left section of my page..
<div id="treeDiv1" style="background-color:#E4DDC0"/></div/> - Add this javascript code at the end of the page
<script type="text/javascript"/>
//global variable to allow console inspection of tree:
var tree;
//anonymous function wraps the remainder of the logic:
(function() {
//function to initialize the tree:
function treeInit() {
buildRandomTextNodeTree();
}
//Function creates the tree and
//builds between 3 and 7 children of the root node:
function buildRandomTextNodeTree() {
//instantiate the tree:
tree = new YAHOO.widget.TreeView("treeDiv1");
