* My Changes: instead of an array with elements, provide an array with objects.
* Define the key and value. The key is the element shown in the inputbox that has typeheadmap.
* The combination of the key and value is shown in the dropdown.
* Optionally provide a listener to listen to the selected 'key' and 'value'.
