The following fits in good enough for me.
...
filterDiv : List (Maybe (H.Attribute msg)) -> List (Maybe (H.Html msg)) ->
H.Html msg
filterDiv a n =
H.div (List.filterMap identity a) (List.filterMap identity n)
...
measurements : Maybe (Int, Int)
...
isNotClicked: Bool
...
let
styleHeight m =
...
content =
...
in
filterDiv
[ Just (class "classy")
, when isNotClicked (onClick Submit)
, Maybe.map styleHeight measurements
]
[ Just content
]
