+The view nested module handles creating Jenkins Nested views.
+
+To create a nested view specify ``nested`` in the ``view-type`` attribute
+to the :ref:`view_nested` definition.
+
+:View Parameters:
+    * **name** (`str`): The name of the view.
+    * **view-type** (`str`): The type of view.
+    * **description** (`str`): A description of the view. (default '')
+    * **filter-executors** (`bool`): Show only executors that can
+      execute the included views. (default false)
+    * **filter-queue** (`bool`): Show only included jobs in builder
+      queue. (default false)
+    * **views** (`list`): The views to nest.
+    * **default-view** (`str`): Name of the view to use as the default from the
+      nested ones. (the first one by default)
+    * **columns** (`list`): List of columns to be shown in view. (default empty
+      list)
+
+Example:
+
+    .. literalinclude::
+        /../../tests/views/fixtures/view_nested.yaml
