Collapsible tree navigation can be used to display hierarchical map of a site.
BSEditor: Many sites use tree-like navigation menus in The Design approach, BUT most of these tree controls reload all content of the page to expand/Collapse levels. It is a very annoying thing. You can avoid it in your site with our JavaScript tree. COOLjsTree can expand/collapse unlimited levels of the tree without reload. The script does not require Frame or IFRAME tag for work.
You can configure the tree through the CSS and setup individual items parameters in the javascript configuration file or you can use our On-line Tree Builder to setup tree structure. Samples Gallery and our documentation show you how much you can do with COOLjsTree and help to build your own tree menu. The script available in two editions: Standard and Professional. In most cases tree setup does not require javascript knowledge you can free download CoolJS Tree 2.8.7 now.
