When we are saving a document with attachments, the attachments will be visible in the bottom of the document on both web and in client.
Its not a good manner to show attachments in the bottom of the document. So we want to hide the attachment.
A reserved field is used to hide the attachments. That field is “$V2AttachmentOptions”.
If value = “0″ –> not to display attachment icons
Note: Most of the times this will not work so follow the following method to hide the attachment icons.
