Hello, teachers!!

Please fill in all the necessary items on the application form.---(1)
Please fill out all the necessary items on the application form.---(1)

I know that (1) is correct, but how about (2)?

I would like to know the difference between "fill in" and "fill out."

THANK YOU IN ADVANCE.

fill in means to act as a substitute.
fill out means to gain weight or to grow bigger
Both of them mean, complete when referring to forms and applications, although I would normally say, "I filled in" a form, but "filled out" an application.
