Settings: "true", "false" or "auto" (default)
With "auto" the native element will be used on Desktop and the not-native iPad-style one on iPhone and iPad.
Using the native one on iPhone/iPad would cause rendering problems and instability.

Select an item by its caption. Note - this can be problematic when the caption contains special or formating characters or was build dynamically!
Use the selectIdItem action instead.
