How should we define a config variable of type multidimensional array in schema.yml file ?
Something which I figured out from drupal documentation is that we can define either type mapping for string value of array or type sequence for integer value or string value of array.
But I'm not sure how should we define for our multidimensinal array, as we have to mention the key first and then the type of value which can be assigned to that key.
For reference I'm adding the following e.g code
image.style.*: type: config_entity label: 'Image style' mapping: name: type: string label: type: label label: 'Label' effects: type: sequence sequence: type: mapping mapping: id: type: string data: type: image.effect.[%parent.id] weight: type: integer uuid: type: string
