I found this perfect javascript for creating dynamic connected drop down boxes. This script works fine but there is just one thing I want to add but unfortunately I’m not familiar with javascript enough… I want to display small images when an item is selected from the second drop down. An image should be assigned somehow to each selection from the right hand drop down menu in the code and when someone selects something from the list, an image should be displayed next to it automatically.
Can anyone please amend this script for me if this isn’t too difficult?
