  title: Webflow Scaffold a CMS Collection
  summary: Pick a site, create a Collection, add a custom field, then seed it with a first item.
  description: >-
    A from-scratch CMS scaffolding flow. It resolves the first accessible site,
    creates a new Collection on that site, adds a custom field to the
    Collection's schema, and then creates an initial item inside the new
    Collection. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
