Best practice for cases like this is to create a form using XML schema in order to have full control.

However there won&#39;t always be an attachment to be put on, and the form won&#39;t allow itself to be submitted without the attachment. I go into the properties but &quot;Cannot be blank&quot; is automatically ticked and greyed out. Any ideas?
