Any recommendations for third party form builders with advanced date field functionality?
I'm looking for a third party form builder that integrates well with Smartsheet, and provides additional functionality around date fields. We need to be able to easily restrict dates based on pre-set deadlines (i.e. report requests cannot be made for any date less than 12 business days in the future). Ideally we'd like report requesters to be able to view a calendar and only see the dates that meet certain criteria (i.e. more than 'x' days in the future and less than 'x' # of requests assigned to each analyst). Any suggestions?
