Modals are streamlined, but flexible dialog prompts. They support a number of use cases from user notifications to completely custom content and feature a handful of helpful subcomponents, sizes, and more.

When you want your modal to support an animation when displayed and closed. There is a few more things you must wire-up and keep in mind.
Configure the modal to support fade-in/out animations. You'll need to provide a message to handle animation.
Subscription for handling animations
type Msg
= ShowModal
-- Note the extra msg constructor needed
| AnimateModal Modal.Visibility
| CloseModal
update : Msg -> State -> State
update msg state =
case msg of
CloseModal ->
{ state | modalVisibility = Modal.hidden }
ShowModal ->
{ state | modalVisibility = Modal.shown }
-- You need to handle the extra animation message
AnimateModal visibility ->
{ state | modalVisibility = visibility }
-- Animations for modal doesn't work without a subscription.
-- DON´T forget this !
subscriptions : Model -> Sub msg
subscriptions model =
Sub.batch
[ Modal.subscriptions model.modalVisibility AnimateModal ]
view : Model -> Html msg
view model =
Grid.container []
[ Button.button
[ Button.attrs [ onClick ShowModal ] ]
[ text "Show modal" ]
, Modal.config CloseModal
