在react-datepicker中，年份下拉清單未顯示，所有屬性均已傳遞。但仍然缺少年份下拉式選單。

<DatePicker
  name={props.inputName}
  id={props.dateBoxId}
  placeholderText={props.placeholderText}
  autoComplete="off"
  dateFormat={props.dateFormat}
  selected={props.value}
  onChange={(e) => props.changeSelection(e, props.inputName)}
  timeInputLabel="Time:"
  disabled={props.disabled !== undefined ? props.disabled : false}
  showTimeInput={props.showTimeInput}
  minDate={subDays(new Date(), props.minDate)}
  maxDate={addDays(new Date(), props.maxDate)}
  onKeyDown={(e) => {
    e.preventDefault();
  }}
  showMonthDropdown
  showYearDropdown
  yearDropdownItemNumber={15}
  scrollableYearDropdown
/>;
