Hi Mark!\
Try as following. I hope it is helpful for you\

```
$(".select_type").click(function () {    var id = $(this).attr('id');    $("#" + id + "_drop").slideToggle(function () {       $("#" + id + " a").attr({            'class': function (_, oldVal) {                return oldVal === "up_arr" ? "down_arr" : "up_arr"; //Change the class here, based on prev value.            }        });    })});
```
