(1) WP-dTree MENU IN A TREE FORMAT
This plugin provides dynamic navigation trees to replace the standard archives, categories, pages and link lists. They’re widgets so you can setup the awesome tree navigation with drag & drop ease, but it also exposes several new template tags for developers.
ADDITIONAL WP PLUGIN INFO
The original ‘WP-dTree’ was created by Christopher Hwang in ~2005. By 2007 Mr. Hwang seemed to have dropped of the internet for good so Ulf Benjaminsson forked the plugin in and named it ‘WP-dTree 3.0’
The fork was focused on performance improvements – mainly caching – but soon expanded to add a lot of new features and modernizations; compatibility with WP 2.7 through WP 3.3, widgets, out-of-the-box Scriptaculous support, link trees, feed icons and more.
For version 4.0 the entire plugin has been rewritten from scratch by Ulf, bringing it in line with the much matured WP 3.x API.

(2) CMS-like tree overview
Adds a CMS-like tree overview of all your pages and custom posts to WordPress – much like the view often found in a page-focused CMS. Within this tree you can edit pages, view pages, add pages, search pages, and drag and drop pages to rearrange the order. CMS Tree Page View is a good alternative to plugins such as pageMash, WordPress Page Tree and My Page Order. Page management in WordPress won’t get any easier than this!
