Sorry to be a pest, I know you and the team are swamped... I've asked this question at least 3x since Nov 2018 and for some reason, I can't seem to get your attention on this... The last time you acknowledged the issue was Reply #12393 on Nov 30, 2018 where you said that you would be working on the issue at that time, but since then displaying grouped fields via Beaver Themer remains broken...
Is this something you are working on, or perhaps it's fixed and I'm just an idiot because I can't figure out how to insert the grouped fields correctly? 🙂
Sorry for replying late. I've looked at the problem for many times, and to be honest, I haven't figured out a good way to do that with BB. The only think that I imagine that can work is integrating with a template system like Twig, so people can write markup for the field. But it's too much work and I couldn't do it at the moment.
My suggestion for now is creating a shortcode to display a group, then use the shortcode in BB. It's the way I'm doing at the moment.
