My custom field I am trying to add to Meta Box Builder however the settings fields are all under the draggable wrapper and cannot be edited to configure?
I have created a private gist in case want to look at code
Currently, we don't support customization code like the custom field type. However, can you please let me know the issue that you have (screenshots or a screen record)? I will check it and see if there's something we can improve on our side.
