  • type
    Specifies whether the DateBox allows users to select one of the following types:

    • "date"
      Users can select the date from the calendar, or they can type in their own date value (in the required format).

    • "time"
      Users can select a time from a range between 12:00 AM and 11:30 PM at 30-minute intervals, or they can type in their own time value (in the required format). Specify the interval property to set the time interval.

    • "datetime"
      Users can select the date from the calendar and the time from the spin and dropdown editors. They can also choose the Today button.
