Allow demos of components with nested properties

Working on it, see the attached MR. I will go back on this tomorrow to review if it is possible to add a different form element type for each property type.

Question,

Was this stated somewhere on the original SDC definition?

I mean, I think it is indeed possible, but working on SDC so far, when this happens I prefer to use slots to have components in components.

Hello Alejandro,

First of all thanks for your work on this module, we already implemented it on several projects and planning to make it a must-have on our stack.

Im thinking about a component with multiple links, where you want to trigger SDC prop validation to make it easier for content editors.

props:
  type: object
  properties:
    links:
      title: Links
      type: array
      items:
        type: object
        properties:
          url:
            title: Url
            type: string
            format: uri
          title:
            title: Text
            type: string
          classes:
            title: Text
            type: string
            enum:
                - btn-primary
                - btn-secondary
                - btn-link

According to https://www.drupal.org/docs/develop/theming-drupal/using-single-director... → its allowed a prop of type: array
