You can describe the problem in a little more detail?
As you write, it works for WordPress V6.4.
Our Block is no add-on for the core Group Block, it is a own Block.
Thanks for the fast reply Daniel. Ah! Somehow I was expecting only functionality for the existing group block. Your plugin and block is working perfectly. Thanks a lot! Will give it a 5 star rating.
The idea is correct, but Gutenberg’s JavaScript and PHP APIs still use a lot of ___experimental flags and developing for old and new WordPress versions is not easy, even with small amounts of code.
However, Gutenberg’s extensions for CSS are more stable, we take a look at a recent blog post.
Thanks for a 5-star rating and using the block.
