How do I create a list control using Rich Text in FLEX?

I'm a FLEX newbie trying to port a Javascript prototype to FLEX. One of my initial prototypes was an unordered list (ul) that had list items that had rich text, i.e. I had a mix of text with different style and colored text and some images inside each element. I looked at the List control for FLEX and it only supports simple string and icon. How can I do rich text list management?
