    569569        gender = models.CharField(max_length=1, choices=GENDER_CHOICES)
    570570
     571You can also collect your available choices into named groups, which will
     572be used for display purposes::
     573
     574    MEDIA_CHOICES = (
     575        ('Audio', (
     576                ('vinyl', 'Vinyl'),
     577                ('cd', 'CD'),
     578            )
     579        ),
     580        ('Video', (
     581                ('vhs', 'VHS Tape'),
     582                ('dvd', 'DVD'),
     583            )
     584        ),
     585        ('unknown', 'Unknown'),
     586    )
     587
     588The first element in each tuple is the name to apply to the group. The
     589second element is an iterable of 2-tuples, with each 2-tuple containing
     590a value and a human-readable name for an option. Grouped options may be
     591combined with ungrouped options within a single list (such as the
     592`unknown` option in this example).
     593
    571594For each model field that has ``choices`` set, Django will add a method to
    572595retrieve the human-readable name for the field's current value. See
    573596`get_FOO_display`_ in the database API documentation.
