When 'Show Submit Button - Yes' is set, students can directly type the assignment or attaches a file and click the [Save] button.

This phase is called 'Draft (Not submitted)', and students can still revise the assignment until the deadline.

At this time, you must click the [Complete Assignment Submission] button to submit it completely.

The phase will go up to 'Submitted for grading' if you click this button and students no more can hand in their assignments even if there's time for the deadline.
