Grey-out ( disable ) past dates and today date in Zoho creator calendar for Date-Time field.

Grey-out ( disable ) past dates and today date in Zoho creator calendar for Date-Time field.

Hi,

I want the user to choose a date only after 24 hours. To explain this point, If I am filling in the request form today I can only choose a date 24 hrs from now and the date prior to 24 hrs will be greyed out.

How can this be achieved ?
