Django create CRUD views using HTML and Modelforms for Multiple ManytoMany Items.

class Category(models.Model):
display_name = models.CharField(verbose_name="Display Name", default=None, blank=True, null=True, max_length=255)
id_no = models.CharField(max_length=200,verbose_name="ID", null=True, blank=True)
band = models.CharField(max_length=200, verbose_name="Band", null=True, blank=True)




class Book(models.Model):
sr_id_no = models.CharField(max_length=200, verbose_name="Sr/ID No.", null=True, blank=True)
physical_condition = models.CharField(max_length=200, verbose_name="Physical Condition", null=True, blank=True)
display_name = models.CharField(verbose_name="Display Name", default=None, blank=True, null=True, max_length=255)
category = models.ManyToManyField(Category,verbose_name="Category Detail", related_name='categoryIt',blank=True)

Make a Create and Update views where i can create a new instance of book and dynamically add Categories on the same page.
1. the order of categories must be preserved.
2. Updation is also necessary in the same manner.
