jQuery Horizontal Tree is a jQuery plugin for visualising data in a tree structure. This plugin supports add, edit, delete functionality with ajax and also supports drag and drop for re-organisation of nodes.

A plugin that allows you to render structures with nested elements in a tree structure. To build the tree you need is to just make a single line call to the plugin and set parameter and supply the HTML element Id for a nested unordered list element that is representative of the data you’d like to display.
