Advanced Hack - Categorizing Blogger Beta Labels and Turning Them Into a Navigation Bar

This is a nearly perfect hack that utilizes the Blogger Beta label feature — transforming labels into hierarchical layers and then converting them into a navigation bar. This plugin has the following features:

1. The "keywords" in the navigation bar are actually the labels we define;

2. The labels are divided into two layers (at least visually). By default, the navigation bar only displays the higher-level fields (parent labels). When you click on one of these fields, the corresponding lower-level fields (child labels) are listed below — this method of handling labels ensures that the navigation bar does not become cluttered with too many fields, thus maintaining its aesthetic appeal.

By using this plugin, articles can be categorized more effectively and presented to readers.
