Vertical and horizontal drag/drop node tree

I was recently experimenting with a html tree which can manipulate it's nodes by drag and drop. I wanted to make it horizontally and vertically growable. When I was almost done, I had to rush for a much simpler version of this without the drag/drop part. I think the code I have written so far might be a good starting point to someone who is trying to do the same thing.

The above code use script.aculo.us Prototype and YUI javascript libraries together. Now I am realizing that, using YUI alone might be a better solution for this since YUI also comes with the drag/drop support.

Overriding default look and feel of GREG - 5.3.0

Using javascript to Include a html file inside another html file

When there is no server side functionality needed we create the whole site in plain html. Usually these sites have left/right side menu, top header, footer etc.. If the site grows in to 20, 30 pages, it will be a headache to do a simple change like changing footer text. We will have to change each page. If we were using a server side technology like PHP, JSP, etc.., we will have the chance to keep the common areas in the site in different pages and include these parts in each page using a “include” statements. We can do the same thing with the plain old html and javascript. But how? First you need to create the site main layout using divs and give them unique ids. <html> <title>HTML Includes</title> <script language="javascript" src="js/main.js"></script> <script src="js/prototype.js" type="text/javascript"></script> <script language="javascript" xml:space="preserve"> // <...
