The core blocks can be defined with an “example”, so when you hover over them, you see the “example” already.
registerBlockType('kennisnet/block-support', {
title: 'Support',
icon: 'phone',
category: 'kennisnet',
description:...
example: {
attributes: {
content: 'Lorem ipsum dolor sit amet, <a href="#" >consectetur</a> adipiscing elit.'
}
},
This would be a nice feature for ACF too, since now the editors that work with the system can not really tell what block they will need.
A generated “example” of the ACF blocks would help them tremendously.
