How to show or hide input field in django admin?

Question

Django

For example, there is a model:

class Receipt(models.Model):
    sum = models.FloatField(verbose_name='Сумма')
    com = models.TextField(verbose_name='Коментарий', blank=True, null=True)
    type = models.CharField(max_length=2, choices=MONEY, default=CASH, verbose_name='Вид движения средств')
    date = models.DateField(default=timezone.now, verbose_name='Дата прихода')
    category = models.ForeignKey(CategoriesOfReceipt, on_delete=models.DO_NOTHING, verbose_name='Категория')
    deal = models.ForeignKey(Affairs, on_delete=models.DO_NOTHING, verbose_name='Дело', blank=True, null=True)

In the admin panel, respectively, all fields are visible.
How to make the field "deal" not visible. And when you select a certain "category", "deal" was shown?

Since this is on the client, you will have to write code in js, the usual work with the DOM and events.
