 short_description: Composes a list with nested elements of other lists or dicts which can depend on previous loop variables
 author: Felix Fontein (@felixfontein)

-  - "Takes the input lists and returns a list with elements that are lists, dictionaries,
-     or template expressions which evaluate to lists or dicts, composed of the elements of
-     the input evaluated lists and dictionaries."
+  - Takes the input lists and returns a list with elements that are lists, dictionaries, or template expressions which evaluate
+    to lists or dicts, composed of the elements of the input evaluated lists and dictionaries.

     description:
-      - A list where the elements are one-element dictionaries, mapping a name to a string, list, or dictionary.
-        The name is the index that is used in the result object. The value is iterated over as described below.
+      - A list where the elements are one-element dictionaries, mapping a name to a string, list, or dictionary. The name
+        is the index that is used in the result object. The value is iterated over as described below.
       - If the value is a list, it is simply iterated over.
-      - If the value is a dictionary, it is iterated over and returned as if they would be processed by the
-        P(ansible.builtin.dict2items#filter) filter.
-      - If the value is a string, it is evaluated as Jinja2 expressions which can access the previously chosen
-        elements with C(item.<index_name>). The result must be a list or a dictionary.
