A simpler way of describing [what’s being asked for here](https://meta.discourse.org/t/category-bundles-aka-category-intersections/35278/) is that this would essentially mean supporting intersection pages for categories, same as we already do for tags: > [@Tag intersections page](https://meta.discourse.org/t/tag-intersections-page/47952): > > I’m currently working with @bedhed in the preliminary stages of working on the bidirectional nav / Table of Contents features described [here](https://meta.discourse.org/t/paid-fullstack-dev-for-bidimensionnal-navigation/45388/5). One slightly large piece missing from this work is a page which could display an ‘intersection’ of tags, (ie, topics which have both the ‘pr-welcome’ and ‘votes-friendly’ tags). A mockup is here: Two questions: Is this a change that would be welcome / tolerated in core, if it were true that it didn’t change any existing functionality? (This s… So just like we’re currently able to do this with tags: ``` https://meta.discourse.org/tags/intersection/docker/email ``` This feature request asks for the ability to do something like this with categories: ``` https://meta.discourse.org/categories/intersection/support/howto ``` although ideally the category intersection wouldn’t need to be defined by a series of categories listed in the URL, but rather a single identifier: ``` https://meta.discourse.org/categories/{custom-name} ``` * * * There’s not a strong use case for it here on Meta, but [discourse.codecombat.com](http://discourse.codecombat.com) could really use this for their [“Other Languages” category](https://discourse.codecombat.com/c/other-languages). That’d allow them to use sub-categories for each of their language categories, while still being able to bundle those language-specific categories together. The Rust community could possibly merge their users and internals forums, which would be a big win. Doing this properly does involve more UX work than the tags equivalent though. --- _[View the full topic](https://meta.discourse.org/t/category-intersections/79932)._
