Reference default blueprint directory in plugin's index.php

The CMS Questions

Hi folks,

i created a bunch of plugins for my current project. Now i want each plugin to make use of a centralized field. How would the correct path look alike?

My current structure:

- site
-- blueprints
--- fields
---- padding.yml (This is the centralized field which i want to use in all plugins)
-- plugins
--- myplugin
---- blueprints
----- myplugin.yml (Here i refer the field 'padding')
---- index.php (Here i am trying to register the padding.yml)

index.php:

<?php

Kirby::plugin('su/myplugin', [
  'blueprints' => [
    'blocks/myplugin' => __DIR__ . '/blueprints/myplugin.yml',
    'fields/padding' => '/blueprints/fields/padding.yml', // THIS IS PROBABLY WRONG?
  ],
  'snippets' => [
    'blocks/myplugin' => __DIR__ . '/snippets/myplugin.php',
  ],
]);

myplugin.yml:

name: 
  de: Mein Plugin
  en: My plugin

tabs:
  main:
    label:
      de: Einstellungen
      en: Settings
    fields:
      headline:
        type: text
        label:
          de: Titel
          en: Title
      padding: fields/padding (Here i am trying to make use of the centralized field)

padding.yml:

padding:
  type: radio
  default: none
  label:
    de: Zusätzlicher Abstand
    en: Additional padding
  options:
    none:
      de: Keiner
      en: None
    padding-s:
      de: Abstand S
      en: Padding S
    padding-l:
      de: Abstand L
      en: Padding L

The error here is that you are trying to register something that is not located in your plugin. Everything you register in your plugin should be inside your plugin folder.
