Working with other content
To refer to existing content, use the Link or LinkCollection to create internal or external links.
- Use Content area to display content from other content.
- Use ContentReference, ContentReferenceList (new from version EPiServer.CMS.UI 8.6.0), or URL to link to a single content of a specified type.
- Use the AllowedTypes attribute to further restrict the kind of links that are possible to add to a property, (although there are a few known limitations).
Use a content reference with many different UI hints to select different entities in EPiServer, such as a block, a media item, a block folder, a media folder, and so on.
