Blocking already selected dates in Smartsheet Forms

edited 12/09/19 in Smartsheet Basics

Hi All,

I have a smartsheet form setup to allow users to book events. I have added a calendar option in there to allow them to choose the date.

I would like to block/grey-out the dates which have already been chosen. Currently I see no option when editing the Form which would let me do that.

Is there a native way to achieve this? Or would I need some API integration? If so, can you share a document.


Thank you!
