In the Grades window, I can see the drop down menu for the continuum grading (see Grades - Drop down menu for continuum grading.png).
In the Grade detail panel, I don't see a drop down menu for continuum grading (see Grade detail panel - no drop down menu.png). Teachers could enter any text. If the enter something beyond the continuum grading, there is an error message (see Grade detail panel - grade entered error message.png).
In the SpeedGrader window, there is no drop down menu for continuum grading (see SpeedGrader - no drop down menu.png).
Ideally, I'd like for all grading views to see the drop down menu so teachers can enter grades.
