How to split a model into several blocks in the admin panel?

Question

Django

there is models.py (example)

class PersonSex(models.Model):
    sex = models.CharField(max_length=10)

    def __str__(self):
        return self.sex


class FamilyStatus(models.Model):
    family = models.CharField(max_length=20)

    def __str__(self):
        return self.family

class Seeker(models.Model):
    user = models.ForeignKey(User)
    # Person Info
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    birth_date = models.DateField(null=True, blank=True)
    # Common Person Info
    sex = models.ForeignKey(PersonSex, null=True, blank=True)
    family_status = models.ForeignKey(FamilyStatus, null=True, blank=True)

in this case, all models in the admin panel are in the same category with the name of the application. can they be separated so that PersonSex and FamilyStatus are in one category and Seeker in another?
UPDATE:
Found a similar situation on StackOverflow and suggest using

class Meta:
    app_label = 'some new app'

but it doesn't work if the model is used as a ForeignKey

Answer 1

In the old days, a tuple of two values ​​was enough for the sex field!
Maybe django-modeladmin-reorder will help you .
