At the portfolio part of the Reel theme there is the possibility to add some extra information. https://demo.wpzoom.com/reel/work/ + https://demo.wpzoom.com/reel/gallery/last-night-in-paris-pure/
You can add Director and Year of Production. This feature is not available at other themes. For instance Inspirio. Or I cannot find it.
IS there a way to add extra fields? IS there a way to add this feature to other themes? And is there a way to use child thems, to edit the specifi portfolio php files?
