Styling a ComboBox control’s dropdown menu

Here is a basic example of formatting the Flex ComboBox control’s dropdown menu using Cascading Style Sheets (CSS). In this example we create a 3 pixel drop shadow on the right of the dropdown menu, as well as round each of the corners on the drop down by 5 pixels.
