Returns the value from the item field that is filled on a website.
Based on the item field for the item type that is used for the website.
In page, paragraph and module templates you also can use: Item.Area[FieldSystemName]. In Razor you can use Pageview.Area.Item["FieldSystemName"].
The Item.Area.[FieldSystemName] tags and loops are not available in DwTemplateTags / @TemplateTags for paragraphs and modules which is intended behavior because these tags and loops are a part of the Master/Page layout Template and they are rendered through the Master/Page template. If you want to find the available Item.Area tags and loops then add DwTemplateTags tag to the Master/Page layout Template.
You can also render item field content with the Item.Area.Fields loop.
