date dropdown box spesifications

[curiosity]

Good day all,

I am trying to create a fillable PDF document but i am trying to add a dropdown box with the Calendar inserted but it should have certain critearia

I want to create the Caendar box similar to some airlines where 3 days from todays date is blocked out and you cannot select them. This will be for making a booking form and the form must be completed 3 days in advance.

If anyone has anything that will steer me in the right direction that will be truly appreciated
