see the tree on left side of the link: http://www.jia.it/index.php
It is very light - once you click it, all are expanded or clapsed.
I saw other trees which are quite heavy - you have to wait for a while for expanding or clapsing tree items.

question:
Do you have code of the tree - very light one? if yes, give me a link to or submit here.
Is the code in HTML (with script) or php file format?

Thanks, I have downloaded zip files.

A question:
It uses JS file:
does JS file work on UNIX and other web-browser (not MS IE)?
i read its code simply - is js file same as css file? my knowlogy about js file is zero.

JS is client side, meaning it's controlled by the browser, not the server. Should work on any server platform, but will depend on browser and user settings whether or not it works.

if so, what is diffrence between js and css?

CSS is presentational markup, colors, placement and so on.
JS is a scripting language, meant to manipulate the page, such as menus, form validation and more.

JS is browser dependant, as previous posters said. Most graphical/GUI browsers support JavaScript.
