I am making an insurance related form where only "none" is selected option in the list of occupation. What is the best way represent it so that user go through all options before selecting "None".
I am currently using a drop-down with 'None of the above' as last option.
An example to clear what I am asking - let's say there are 5000 models of cars and only 50 of them are not allowed. I want user(its given that every user owns a car) to select none if user don't own any of those 50 cars.
