Using choices together with user input in Django

I am creating a model with fields that will provide choices for the user so I am using keyword choices like this:

ACQUIRED_FROM=(
    ('dealer', 'Dealer'),
    ('private', 'Private'),
    ('show', 'Show'),
    ('family member', 'Family Member'),
    ('other', 'Other'),),

and specifying the field like this:

acquired_from = models.CharField(max_length=100, choices=ACQUIRED_FROM)

Under family member I need the user to input the specific person (e.g. father, uncle, e.t.c).

I think it will also apply to a currency field that will enable the user to choose whether the input is in dollars or euros and then specifying the amount.

The question is how can I define the choices to enable user input?

This is a simpler way to ask the same question above:

LENGTH=(
    ('CENTIMETERS', 'cm'),
    ('INCHES', 'in'),),

With this I would like the user to select either inches or centimeters and then input the actual value. How should I modify it?

Django choices is not meant for dynamic content.
If your intention is to build nested choices (aka group choices), you can pre-define the list of choices for family member the same as you defined it for acquired_from.

ACQUIRED_FROM = (
    ('dealer', 'Dealer'),
    ('private', 'Private'),
    ('show', 'Show'),
    ('Family Member', (
            ('father', 'Father'),
            ('uncle', 'Uncle'),
         )
    ),
    ('other', 'Other'),
)
