I've just created another infobox. A part of the code looks like this:

It means if there is a variant, it would link to another page. Code in article:
 * list = yes // parameter can be anything, just to make the  tag appear.
 * air = Goblin
 * water = Pegasus
 * fire = N/A
 * earth = Nymph

What I was hoping for is to somewhat make the code simple, and less redundant, like this:

N/A means the article does not exist and there is no link. Now, I have seen some templates that use a style like this. I just never understood what and how.  
 * list = Goblin, Pegasus, N/A, Nymph
