You can use LayGridder with Gutenberg thanks to acf-native-fields and my proposed change in this issue. As I mention there, I haven't tested if my change breaks it for non-Gutenberg sites but it works (moving both #gridder and #gridder-modals).

Keep in mind it's also better if you use ACF 5.8.0 beta2 so you don't see all kinds of empty acf meta-boxes.

Dear @rsepierre
That is a great idea! Thank you for your valuable thoughts. We will take this into account!
Thank you for using LayGridder!

Best,
Felix

It started as a random error but now just appeared and won't go away.
Both console and log file are not showing any error. I could simply deactivate all PHP warnings, but would be nice to have it fixed :))
