# Self Service Date Picker > [HTML Version](selfservicedatepicker.htm) The concept is similar to the self-service combo (where you put "..." in the _setdef_ parameter and it returns _exitcode_ 29 when you attempt to display the drop-down), except here you activate it by adding _type_ **||v** to the date _type_ codes. Presumably this might be useful in cases where you like the look of the edit portion of the date picker, but want to display a more specialized calendar when the user clicks the drop-down button. See [Date Picker Control (INFLD)](datepickercontrol(infld).htm.md) in AUI[xs](keyword-types.htm.md) for related information.
