optionalDropDown

fun <T : Any, M : ListModel<T>> optionalDropDown(model: M, boxItemVisualizer: ItemVisualizer<T, IndexedItem>, listItemVisualizer: ItemVisualizer<T, IndexedItem> = boxItemVisualizer, unselectedBoxItemVisualizer: ItemVisualizer<Unit, IndexedItem>, unselectedListItemVisualizer: ItemVisualizer<Unit, IndexedItem> = unselectedBoxItemVisualizer, config: (Dropdown<T?, *>) -> Unit = {}): FieldVisualizer<T?>(source)
