Add attachments to PDF annotation

WebViewer supports attachments for annotations, and this currently enables attaching files to the replies in notes panel.

When adding a reply, the user can click the attachment icon to add attachments to their reply. If the file format is image-based, a preview will render.

After posting the reply, the attachments added will show with the note content. The attachments will persist after downloading.

Clicking on the attachment will open it in a new tab inside WebViewer. Note that you need to enable the MultiTab feature first.

JavaScript

instance.UI.enableFeatures([instance.UI.Feature.MultiTab]);
