ParticipantI'm building some blocks using Meta Box Builder, and I like the process so far.
Unfortunately, none of my blocks have previews, and I can't quite figure out how to add them within Builder itself.
I see how to do it in MB Blocks in the docs and in other forum answers. But I don't see a corresponding set of fields in Meta Box Builder. Is there a way to render previews from Builder?
Thanks for your help.

ModeratorHi Matt,
Meta Box Builder does not support full coding settings. We will try to do it in future updates. For now, please use the code to show the block preview.
September 29, 2021 at 1:43 PM #31065ParticipantHi Long. Thanks for your help.
When you say that I should use the code to show the block preview, what is the syntax for that? Is that where I’d use
is_preview?September 29, 2021 at 3:37 PM #31068matija
ParticipantWhere do I put the code in Meta Box Builder to show preview?
September 29, 2021 at 8:24 PM #31071ModeratorHi,
The variable
is_previewlets you know if you’re in the preview mode for Gutenberg or on the front end. It’s useful when you want to display a custom message to users when they edit the block on the back end. See my screenshot https://imgur.com/s295oqk https://imgur.com/r9025ZvGet more details here https://docs.metabox.io/extensions/mb-blocks/#render_callback
If you use the block setting
preview, the content will show on the small preview area. Screenshot https://imgur.com/mMB5a5mGet more details here https://docs.metabox.io/extensions/mb-blocks/#preview
September 29, 2021 at 8:37 PM #31073ParticipantThanks, Long. I see how
is_previewworks now.What I hear you saying is that Meta Box Builder does not yet have a way to set the block setting
preview, so it is not possible to generate the small preview with Builder. And if that is important enough, we should code the block in MB Blocks instead.Did I get that right?

Yes. To use all settings of Meta Box and extensions, I recommend using the code. You can also manage and customize custom blocks the way you want.
