Picklist default value does not allow null and force selecting
In Zoho Campaigns, we have picklists for registering on a signup form. The field is mandatory but it defaults to the first item. Can this be made to default to a null value so the user does not inadvertently leave the value unchanged and hit submit? I have tried making it say "Please select" as the first item but that allows the user to select the value "Please select" which is not what we want.
