Django Model Form Integer as Drop Down

Question

I have a simple Model form in my project as follows:

class InviteForm(forms.ModelForm):
    class Meta:
        model = Invite
        fields = ['max_guests', 'rsvp_guests', 'rsvp_attendance']

Max Guests is just an integer and appears for the user to type in. As the value is always small (<10), I would like this to be a dropdown instead with all values 0-max.

Is there a way to overwrite an integer input as such?
