Hidden field properties

Example where a hidden field is used to store the type of a link, in this case an external link.

form:
  tabs:
    - name: tabLink
      label: Link
      fields:
        - name: link
          class: info.magnolia.ui.form.field.definition.TextFieldDefinition
          label: Link
        - name: linkTitle
          class: info.magnolia.ui.form.field.definition.TextFieldDefinition
          label: Link title
        - name: linkType
          class: info.magnolia.ui.form.field.definition.HiddenFieldDefinition
          defaultValue: external
          type: String

The only relevant common field properties you can use to configure the hidden field are defaultValue and type.
