I clearly understand what you mean and I have exactly the same problem as you. Is there any solution for solving this?
I started to have my first attempt with ACF + InnerBlocks and ran into exactly the same problem. Ist there any solution for this?
Is it possible to display a sub field value?
Example: The sub field within a repeater is a text field where the user can submit a post ID. Next to this entry I want to display by a message field the title of this post.
Is this possible?
Many thanks in advance!
Thank you, @hatsumatsu, great solution. This works for me also perfectly!
