    Yes, blocks are not the answer in your case. You can more than likely keep your existing meta boxes. See https://wordpress.org/gutenberg/handbook/designers-developers/developers/backwards-compatibility/meta-box/

    Your boxes will not have their own panel like the Yoast one, but they will appear on the screen somewhere. For the creation of panels like Yoast’s, I’m not sure how myself. New to me as well. You can peruse the rest of the linked handbook, or study the Yoast plugin to see what they did.

    Thank you for your answer. Would be great for us to keep the existing meta boxes but there are a couple of problems:

    1 – It’s not clear how long the meta boxes will be supported
    2 – For our commercial products distributed through the Envato Market one of the points required in the Gutenberg Optimized Definition is to “Convert any metaboxes created by the plugin to blocks / controls in Gutenberg.” and we have to do something about this. Be compliant or try to discuss these requirements with Envato.

    In general there are a lot of plugins with meta boxes used to save meta data that should not have an association with specific Gutenberg blocks and a sort of documented standard solution that don’t require to reverse engineer other products would be much better. Not only for the time required to understand how this is achieved by Yoast SEO for example, but because copying what can be an hack/workaround is not optimal.

    There is no indication that meta boxes will not be supported. If you add your box with a “side” context, it appears in the document panel, which is little different than putting a box in its own panel. It’s the same UI either way. I’m pretty sure the Yoast content is still a meta box, except it was added to a new context. What’s missing for us I think is the creation of a new context. Just a hunch, unverified.

    No, you couldn’t copy open source code into a commercial product. I was thinking more along the lines of observing their process, setting it aside, then developing your own along similar lines. It’s not really any different than my telling you how to proceed or following a tutorial, it’s just the “language” of the presentation is different 🙂

    Thank you again for these details. It seems that this can be done with the plugin sidebar feature. I just got this suggestion on GitHub https://github.com/WordPress/gutenberg/issues/12710. I’m going to test this in the next few days.

    Yes, this was clear.

    That’s exactly how it’s done in the Yoast plugin. You can see it being set up in the code here:

    https://github.com/Yoast/wordpress-seo/blob/87e407ca153285ecef4c0b6f46837338812df88a/js/src/edit.js#L122

    I’m not sure how up to date it is, but there’s this tutorial I found on setting up one of these sidebar blocks, that might be of use:

    Good luck with it!
