I have added a datepicker field on rails view. (from and to fields). This is my form. I want the to field automatically filled once I select the date on from field with 10 days later.from=(2020/01/20) then to field to be auto to(2020/01/30). Also I donot want to use date-select, because i need it in same design that It is now, but Can I disable the input field with only select the datepicker but no typing of any string?
