Working with other content
There are several different ways to refer to existing content. You can use the Link or LinkCollection to be able to create internal or external links. Content area to display content from other content or ContentReference / URL to link to a single content of a specified type. It is also possible to use the AllowedTypes attribute to further restrict which kind of links that are possible to add to a property although there are a few known limitations to this currently.
A content reference can be used with many different UI hints to select different entities in EPiServer, for instance: a block, a media item, a block folder, a media folder etc. There are also more hints in other EPiServer products like EPiServer Commerce.
