Custom Category - Multiple Snippets & Dropdown Lists

[KiwiBlaze]

Greetings Workians

I'm currently learning Realm Works, and currently playing in the Manage Categories section and have discovered the need for two things that I don't know - thou I'm sure there will be more later.

The first thing I'm trying to find, is a way of creating a new Category that when a new snippet is requested in World Almanac that multiple snippet's are added because of that request.

For example: When adding a new planet, there are always three snippets that make up one entry for this new addition. 1) Name, 2) Descriptions, 3) Images.

Is there a way to add a "New Planet" that will add all three of these snippets?

The second thing I have discovered, is that for different snippets than above, some information is always one answer of a set number of answers. I would like to know if there is a way to form a kind of "Dropdown List" that can be selected, instead of typing the answer each and everytime?
