I created a plugin for all my custom blocks and modifications to default blocks. When I try to extend the default “heading” blueprint in my own blueprint like described in the “Extending Blocks” section in the references, my backend doesn’t load anymore. It gets stuck. The Kirby icon in the top right corner keeps spinning forever.
Here is my blueprint:
fields:
blocks:
type: blocks
fieldsets:
heading:
extends: blocks/heading
fields:
customId:
label: Custom ID
type: text
I guess the problem is that “extends: blocks/heading” is not visible from within a plugin? Is there a way to achieve what I’m trying to do?
Thank you!
