See this JavaFX FXML ComboBox demo app. For dynamic data you can either dynamically generate your fxml using something like Velocity or, probably better, populate an ObservableList and provide it to your fxml injected ComboBox instance.

Here is a modified version of the demo app which populates the ObservableList of ComboBox items in the controller initializer.
