Column Navigation 介绍
Column Navigation provides a Mac OS X/NeXTStep style navigation for unordered
HTML lists. (Ordered lists will be supported in version 1.1)
It has been designed to progressively enhance list @R_373_4045@ion by refactoring
it into columns of data. Each column represents the children of the proceeding
selected item.
This is especially useful for formatting long hierarchy structures.
An example of the menu in action can be seen
