AJAX LiveTree : JavaScript/DHTML Tree
LiveTree implements a JavaScript/DHTML tree (hierarchical list) widget that loads data asynchronously as-needed (using AJAX). This makes it ideal for cases where the dataset is too large to load to the browser all at once. Data can be provided in the HTML page as well, in which case no asynchronous loading is needed, making this widget suitable for standalone client-side use.
LiveTree consists of two components: client-side JavaScript code that runs in the user’s browser which displays and allows the user to navigate the tree, and a server component that provides data to the client. The client-server protocol is very simple, which means server components can be easily created for just about any web server configuration with minimal effort. Presently, the only existing server component is for Ruby On Rails.
