Sitecore Source Property
The Sitecore source property is used in an endless number of contexts within Sitecore. In this example, it’s a property on the Multilist field “UpComingNews”. It’s one of my favourite “clever” bits of Sitecore in that it can take an amazing number of formats. You can choose a node in the Content Tree, or use a complex XPath or search query, or in this case, it actually references a custom class.
