Using remote options is a nice feature of the select field.

repository/path properties are more or less documented together, but we could use a dedicated section for "Using remote options".

In particular, combining these with labelProperty and valueProperty can prove to be quite powerful.

fields:
  - name: selectWithRemoteOptions
    class: info.magnolia.ui.form.field.definition.SelectFieldDefinition
    label: Contact
    repository: contacts
    path: /
    labelProperty: firstName
    valueProperty: jcr:uuid
