You will need javascript here. JQuery would be perfect for the job. I would start by providing a deterministic id for the dropdown because if you run this view inside a template there could be prefixes added to the id which would ruin our javascript id selectors (see below).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
