Dynamic Default Values
When linking to /admin/#/collections/posts/new you can pass URL parameters to pre-populate an entry.
For example given the configuration:
collections:
  - name: posts
    label: Posts
    folder: content/posts
    create: true
    fields:
      - label: Title
        name: title
        widget: string
      - label: Object
        name: object
        widget: object
        fields:
          - label: Title
            name: title
            widget: string
      - label: body
        name: body
        widget: markdown
clicking the following link: /#/collections/posts/new?title=first&object.title=second&body=%23%20content
will open the editor for a new post with the title field populated with first, the nested object.title field
with second and the markdown body field with # content.
Note: URL Encoding might be required for certain values (e.g. in the previous example the value for body is URL encoded).
