Sites in the Website Builder can now keep their content in collections: blog posts, projects, team members, anything that repeats. The content lives in the CMS tab, and the page reads from it.
On a CMS item page, select an element and use the Content row to connect it to a field, or create a new field from there. A Show CMS content toggle draws a ring around every CMS-driven field and list, with a hover chip to edit in place or open the item in the CMS. Text you change with the Text tool saves straight back to the item.
New collections get a generated item page by default. The collection settings have two switches: Each item gets its own page, and Published. With Published off, visitors get a 404 while you can still preview the page, so a draft never leaks. The page is created when it is missing and removed when you switch it off.
