I’m trying to use WP Bakery Grid Builder to layout a custom testimonial grid. For the most part it’s working OK. However, I’d like to include the “byline” which is one of the theme’s custom fields for “Tesitimonials”. However, I can’t seem to get it right when I add the custom field “byline” to the grid builder. I’ve also tried “etheme_byline” Can I do it this way, is this the correct field name?
