Topics are a set of rules that can be customized to allow users to quickly collect and display data of your interest.

Similarly, Sub-topics also allow you to do the same and are nested within main topics.

A combination of topics and sub-topics is often used to better organize and view data.

Radarr allows users to create custom topics and subtopic nesting to allow freedom and ease of viewing data as desired.

1. Topic – Fruits

1. Sub -Topic – Banana
