+Elm - Maybe Map
+===============
+
+Here, a tooltip title attribute needs to be added if it is **Just**.
+
+```elm
+let   
+    divAttributes =
+        [ HA.classList
+            [ ( "my-div", True ) ]
+        ]
+
+    combinedAttributes = 
+        case settings.tooltip of
+            Just tooltip ->
+                divAttributes ++ [ HA.title tooltip ]
+            
+            Nothing ->
+                divAttributes
+in
+H.div
+    combinedAttributes
+    [ content ]
+        
+```
+
+This can be easier written with the [Maybe.map](https://package.elm-lang.org/packages/elm/core/latest/Maybe#map) and [Maybe.withDefault](https://package.elm-lang.org/packages/elm/core/latest/Maybe#withDefault) functions.
+
+```elm
+
+let
+    divAttributes =
+        [ HA.classList
+            [ ( "my-div", True ) ]
+        ]
+    
+    tooltipAttribute =
+        Maybe.map (\tooltip -> [ HA.title tooltip ]) settings.tooltip |> Maybe.withDefault []
+
+in
+H.div
+    (divAttributes ++ tooltipAttribute)
+    [ content ]
