I was in a hurry so I didn't expain much, sorry: Options tag: -collection is a TreeMap (a sorted map by key) in this example, but is can be anything that extends Collection. -property is the thing that will be assigned when the item is selected. Since I'm sorting on key I put my object id in the value position and the display value is my key. You can put them anywhere you want I just did this because I wanted my list sorted -labelProperty is the thing you'll see on the screen
