Answer 1

First list the items in the FXML.
<ComboBox fx:id="userComboBox" editable="false" layoutX="14.0" layoutY="22.0" onAction="#setTimeMultiplier">
<items>
<FXCollections fx:factory="observableArrayList">
<String fx:value="Item 1" />
<String fx:value="Item 2" />
<String fx:value="Item 3" />
</FXCollections>
</items>
</ComboBox>
Then add or remove items from the ObservableArrayList.
userComboBox.getItems().removeAll(comboTime.getItems());
userComboBox.getItems().addAll(...);
