To support dismissable alerts you must keep track of the alerts visibility in your model.

type alias Model =
    { alertVisibility : Alert.Visibility }


type Msg
    = AlertMsg Alert.Visibility


init : ( Model, Cmd Msg )
init =
    ( { alertVisibility = Alert.shown }
    , Cmd.none
    )


update : Msg -> Model -> ( Model, Cmd Msg )
update msg model =
    case msg of
        AlertMsg visibility ->
            ( { model | alertVisibility = visibility }, Cmd.none )


view : Model -> Html Msg
view model =
    Alert.config
        |> Alert.dismissableWithAnimation AlertMsg
        |> Alert.info
        |> Alert.children
            [ Alert.h4 [] [ text "Alert heading" ]
            , Alert.text "This info message has a "
            , Alert.link [ href "javascript:void()" ] [ text "link" ]
            , Alert.p [] [ text "Followed by a paragraph behaving as you'd expect." ]
            ]
