how to add reset button inside Dhtmlx DatePicker in the dropdown for dates
Hello.
Unfortunately such feature is not supported.
The best solution is to place the “reset” out of the calendar, but next to it and call the clear()
method:
https://docs.dhtmlx.com/suite/calendar__api__calendar_clear_method.html
to clear the selected vcalue in your calendar.
You may try to open a feature request in the support system, as you are a licensed user, so it will be observed and such functionality may appear in the future updates, if it has a demand.
