i want to build an application in a tree format?

[Abhishek Reddy]

i want to build an application in a tree format, which is part of my web application?
for example : windows registry
can anyone suggest me the some ideas?

[Ulf Dittmer]

Are you looking for

a tree data structure (client or server?)

a tree GUI element in HTML/CSS/JavaScript

information on persistently storing tree data

or something else?

Let us know what you have so far.

[Abhishek Reddy]

thanks for the reply

It is a web application and has to be done on server side.

for example:
the user will select a tree element, based on it the content has to be displayed on the right side.(the content displayed will be retrieved from the database.)

thank you Ulf Dittmer for the reply.

the tree has to be build dynamically, the tree elements will be obtained from the database.
i.e if the user selects a particular tree element, its sub elements will be retrieved from the database and based on the selected sub element its respective contents will be displayed on the right side.

can you suggest me some libraries?

[Abhinav Srivastava]

html/javascript will do just fine. why do you need a 3rd party library when you can do it yourself!

If this was my problem I would start by making some mock-up plain HTML pages to understand the formatting required to look like what you want.

Next I might experiment with Javascript to expose/hide the content data.

Only after understanding the markup required would I start programming JSP.
