Creating cards with more "fields"?

Hello. I am new to Anki, and the only deck I’ve been trying out is Ultimate Geography (UG), which I found on the shared decks page.

I’ve recently tried to make my own decks for my studies, but I want to mimic the layout of the UG deck. I will elaborate.

If I were to go into the browser of the UG deck and select one of the cards/notes (idk the difference), I can see multiple “fields” (e.g. “Country”, “Capital”, “Flag”, and “Map”); Two of these “fields” are chosen and combined to create the card I see when learning/reviewing the deck (e.g. Country → Capital, Flag → Country, etc.).

What is the method to making these types of cards/notes?

Thank you in advance!

This is a complex deck. It would be good to start simple: add another field, perhaps tags or something similar. Add another note type. You need to understand HTML and, preferably, JavaScript, and AI can help you with a lot of things.
You’ve been given a link to the manual.
I modified this deck for the Russian language, meaning I added a description so it could be explained verbally. I divided it into sub-decks so that those who need it can learn the basics, while those who need to learn the less important ones can learn the rest.

You can take a look at the design, which I found convenient.

Everything you’re considering will be easier once you understand that difference – as well as note types, card types, templates, etc.

Then you can add or clone a note type, set it up with the fields you want, and create your own card types.
