[Answered ]-The "select all" header checkbox that I used in Django 1.5 is missing in Django 1.9

The checkboxes should still be there in Django 1.9. The design for the Django admin was updated in 1.9. Your screenshot still looks like the old style, so it looks like you haven’t updated the static files.

If you are in production, make sure that you have run collectstatic since upgrading.

python ./manage.py collectstatic
