Categories and Subcategories display

I have been trying to reproduce the following display about categories and subcategories (using bullets or boxes) but I didn’t find the way to do it.

Subcategory appears on category’s side.
Example: Search results for 'how to set categories' - Discourse Meta

Is there a guide I could use to reproduce these examples?

I think it’s Settings - category style - bullet.

Thanks for your answer.
Sorry I didn’t explain myself.

So it seems that when using Search (for example) we get a list of given topics.
That list, in case of including topics with subcategories, shows under each topic’s title: Category and Subcategory, with two separated and well defined bullets, as my previous image shows.

But at home, displaying latest topics, categories and subcategories shows as it follows:

I wonder if there is a way to apply first example configuration/display of category/subcategory to home list/latest topics.

In that case, I don’t know - sorry!
