Not really. I saw this already. If you look below, What i am trying to do is select John from a drop down list and the rest of the info would populate. That is john's age and gender as well as the 2 names under him and their age and gender. This isn't what im using it for but its the simplest example i can think of.

Name Age gender
john 21 m
mike 2 m


jill 6 f
