jQuery OrgChart is a plugin that allows you to render structures with nested elements in a easy-to-read tree structure. To build the tree all you need is to make a single line call to the plugin and supply the HTML element Id for a nested unordered list element that is representative of the data you’d like to display.
You can show/hide a particular branch of the tree by clicking on the respective node. It is very easy to style using CSS. If drag-and-drop is enabled you’ll be able to reorder the tree which will also change the underlying list structure.
