Changing polygon color based on drop down list choice

Hi everyone!

So I have this problem that I can't seem to be able to find an answer...

I have a world map, each country is in its own polygon, and I would like to be able to put a drop down list on each country that allows the user to choose the color based on the choice of drop down list item.

For example, the drop down list has 3 choices of "No Color" and "Red" and "Transparent".

When user choose either "No Color" or "Transparent" the color of the country (let's say Australia) under the drop down list is unchanged.

But when the user select "Red" Australia is colored red.

So is there any way to do this easily? I am new to Acrobat.
