Answer 1

This is a form. A form deals with interacting with the user. An IntegerField of forms has no choices. After all the IntegerField of models deals with how we store data in the database.

You can use a TypedChoiceField [Django-doc] for this:

class StudentMarksheetform2(forms.Form):
    SUBJECT_CODE = (
        (1,'CS101'),
        (2,'CS102'),
        (3,'CS103'),
        (4,'CS104'),
        (5,'CS105'),
        (6,'CS106')
    )

    code_title=forms.TypedChoiceField(choices=SUBJECT_CODE, coerce=int, initial=1)
    
    class Meta:
        model=StudentMarksheetdata2
        fields=['code_title']

Answer 2

"forms.IntegerField()" doesn’t have "choices" and "default" options different from "models.IntegerField()" which has "choices" and "default" options.

So, to have Dropdown Single Select Box using the fields(classes) from "django.forms", use "ChoiceField" or "TypedChoiceField" which have "choices" and "initial" options as shown below. *"initial" option is equivalent to "default" option:

"ChoiceField":

# "forms.py"

from django import forms

class StudentMarksheetform2(forms.Form):
    
    # ...
    
    code_title=forms.ChoiceField(choices=SUBJECT_CODE, initial=1)
    
    # ...

"TypedChoiceField":

# "forms.py"

from django import forms

class StudentMarksheetform2(forms.Form):
    
    # ...
    
    code_title=forms.TypedChoiceField(choices=SUBJECT_CODE, initial=1)
    
    # ...
