Group items tagged

To be accessible the PDF form must be created as a tagged document. The goal of the form design is to ensure that all the field elements are placed in the logical structure within the tag tree and have appropriate text descriptors using tool tips or captions.

A PDF file equipped with well-formed tags may be "reflowed" to fit different page or screen widths, and will display well on handheld devices. Tagged PDF files also work better with the screen-reader devices used by many blind and other disabled users. In most cases, tags are necessary in order to make a PDF file comply with Section 508.
