Yes, with a map:
case msg of
DeploySelected deployment ->
let
toggleSelect (d, s) =
if d == deployment then
not s
else
s
in
{ model | deployments = List.map toggleSelect model.deployments
}
The above approach assumes multiple selections and a toggle state where if
you click again on something you deselect it.
