I am trying to create a list that appears when the radio buttons are clicked, I am having a problem with the way the list appears once the button is clicked.
Here is the example http://jsfiddle.net/c2webdev/4bpKE/
Your demo didn't have jQuery set as the framework, your code works perfectly fine however.
Also your two select elements share the same id: myList. The id attribute is suppose to be unique.
