It seems you can only add plain text to extra fields

Sorry, but extrafields in Genoa don't support html/bbcode parsing. This feature was added in Siena where extrafields are reworked.

Sorry for rising such an ancient topic on top, but: how? How do I turn the HTML parsing on in the Extrafields? Can't see a proper option on the admin/extrafields?n=cot_pages page. :(

(Siena 0.9.14, btw.)
