An empty portfolio is no good
You can add work to portfolios in two ways – either from the assignment or in the file viewer toolbar.
While you’re in a student’s assignment, you can swipe left on the file, comment, or grade to get the option to add to the portfolio. Tap on the Star icon to add it! The Star icon can also be seen at the top while you’re in the file viewer. Tapping on the icon again removes it from the portfolio.
Once you’ve opened up a student’s assignment, hover your mouse over the file you’d like to add to the portfolio. Click on the arrow that appears to the very right of the file and then click Add to Portfolio. The Star icon is also available for when you’re in the file viewer.
