Sidebar widget displays a navigable tree of pages and subpages with expand/collapse capability.
This plugin adds a widget that will display a hierarchical tree of all pages and subpages on your site. Drag it to be displayed in any widget area.
Each item in the tree is the title of a page or subpage on your site, which is a hyperlink that will navigate the browser to that page. A deep hierarchy of a large number of pages and subpages is thus reduced to a neatly organized and easily accessible menu. Pages at the same hierarchical level are displayed in alphabetical order.
On a page load, the tree will automatically expand only the branches necessary to reveal and highlight the page currently being viewed. "Expand All" and "Collapse All" features allow you to easily open up and close the entire tree to help find a page buried somewhere in the hierarchy. Reclaim all your vertical real estate altogether with "Show" and "Hide" features.
