            { selectedMsg = PaginationMsg
            , prevItem = Just <| Pagination.ListItem [] [ text "Previous" ]
            , nextItem = Just <| Pagination.ListItem [] [ text "Next" ]
            , activeIdx = model.activePageIdx
            , data = [ 1, 2, 3, 4, 5 ] -- You'd typically generate this from your model somehow !
            , itemFn = \idx _ -> Pagination.ListItem [] [ text <| toString (idx + 1) ]
            , urlFn = \idx _ -> "#/pages/" ++ toString (idx + 1)
            }
        |> Pagination.view
