I’ve created an FAQ block with a nested accordion block, as described at https://getkirby.com/docs/cookbook/panel/block-collection#faq-block-using-nested-blocks
There’s kind of a bug in the summary field where the cursor jumps to the end of the input value if you place it somewhere in the middle and type anything (see attached video).
I suppose that’s mainly a question for you, @texnixe.
