Content Types
Every page is a content type — a Document, News Item, Event, Image or Link. The type decides which metadata a page carries and, if you choose, the layout it renders with. The samples below are live instances you can open and copy.
Image - Light
The Image content type can be used to upload an image in various formats (JPG, GIF, PNG, SVG). The uploaded image should always have a high resolution so that it can be used flexibly, for example as a banner image. Plone automatically delivers the images in the best scaling, so there is no need to scale images down manually.
Page metadata
A page's frontmatter is its metadata — the fields stored alongside the blocks, and what the rest of the site reads instead of the page body. You edit them in the sidebar's metadata panel; in the markdown source they are the frontmatter at the top of each file, exactly like this page's own.
titleanddescription— shown in navigation, in listing and teaser cards, and as the page's title and summary for search and social sharing.review_state—published,private, and so on; it decides who can see the page.effective— the publication date a listing sorts and filters on.preview_image— the image a teaser or listing card shows for this page.exclude_from_nav— hide the page from navigation while keeping it reachable by its URL.subjects— tags, which faceted search and listings filter on.layout— the default view the page renders with.order— on a folder, the order its children appear in navigation and in a relative-path listing.
Forcing a layout per type
A forced layout applies a shared template across a page's whole blocks field — see Templates & Layouts for the mechanism. Forcing is your frontend's call: you pass allowedLayouts, so you decide which layout and when, on whatever logic you want. Keying that on the content type is the common case — force every News Item onto a news layout, every Event onto an event layout — so a whole class of pages stays consistent without an editor choosing per page. The same hook forces on anything else just as well: a section of the site, a flag in the page's metadata, or the current user.
