Doesn't require Smithy Core

Breakdance website has a documentation page. This plugin allows you to build the same page really easily. Instead of a fixed CPT and adding custom scripts - just assign a post type and it's all built for you.

It includes an Ajax search, easy visual sort for the category and terms, automatically built toggle/reveal index and optional support for basic Gutenberg blocks if you build your docs in the default Wordpress editor.

It's fully responsive and allows you to position a sticky mobile menu for page navigation.
