Is it possible to create categories for tags in taxonomies?

Hugo Taxonomies are not hierarchical, they exist side by side.

A couple of years ago @pointyfar shared a way to achieve complex content filtering in a Hugo project with JS.

See:

Filter content by tags, sections, etc using JS

Hello! I am sharing a bit of javascript that I wrote. It allows filtering content across different criteria simultaneously, for example tags, content types, authors etc. This was originally written to filter hugo themes using multiple tags, which I posted about here: https://discourse.gohugo.io/t/filterable-hugo-themes/ but I have spun this off into its own repo to be reusable inside hugo projects.
