OpenAPI 3.2 Tag Objects add a short summary, a parent tag name, and a kind that classifies the tag’s purpose. For example, a nav tag named books can point to products as its parent so documentation groups those operations beneath products. The parent must exist in the description, and cycles are forbidden.
The demo turns a flat tag list into a navigation tree. Check that documentation tooling supports the new fields, and assign kind deliberately so navigation and code generation groupings stay clear.
When to use
Use it to organize navigation in documentation with many operations.
