+
+Example: Use a backend layout in the page content data processor
+================================================================
+
+Define the backend layout via page TSconfig, for example in the site:
+
+..  literalinclude:: _BackendLayout.tsconfig
+    :caption: config/sites/my-site/page.tsconfig
+
+Configure the output via TypoScript, using the content object
+:ref:`PAGEVIEW <t3tsref:cobj-pageview>` and the DataProcessor
+`page-content`.
+
+..  todo: Link Dataprocessor
+
+..  literalinclude:: _BackendLayout.typoscript
+    :caption: config/sites/my-site/setup.typoscript
+
+Use the identifiers of the columns in the Fluid template:
+
+..  literalinclude:: _Default.html
+    :caption: EXT:my_sitepackage/Resources/Private/Templates/Pages/Default.html
