Admin Forum:Optional Template Rows

Hello I'm Awesume I created a wiki called ATPedia a wiki all about tennis pros. I made an infobox template for them but it did not have retired or dead. I want to make the same template for all of the players. How would I make an optional row for retired and died? If you are confused just ask questions. Awesume 17:48, December 21, 2011 (UTC)
