This module is useful if you want to add an TextArea Form element to your app.
Add a TextArea.Model to your model.
type alias MyModel =
{ myTextArea : TextArea.Model
}
init : Model
Add a TextArea.Model to your model.
myInitialModel : MyModel
myInitialModel =
{ myTextArea = TextArea.init -- optionally pipe into State Setters
}
Internal.Msg
Add a TextArea.Msg to your Msg.
type MyMsg
= UpdateMyTextArea TextArea.Msg
update : Msg -> Model -> Model
Use in your update function.
myUpdate : Msg -> Model -> ( Model, Cmd Msg )
myUpdate msg model =
case msg of
UpdateMyTextArea inputMsg ->
{ model | myTextArea = TextArea.update inputMsg mode.myTextArea } ! []
view : Model -> View
Transform an TextArea.Model into an TextArea.View, which allows us to pipe View Setters on it.

[ TextArea.view model.myTextArea -- pipe view setters here, for example |> setIsLocked 'your logic here'
]
render : View -> Html.Styled.Html Msg
