Most of the drop down lists in SpEd Forms are managed by the super administrator. The super administrator can also choose to allow users to add items to any of these lists. When you are allowed to add to a specific drop down list, a link will be provided on the “Drop Down Lists” page. When you add entries to a specific list, the additional entries will only be available to you. No other user will be able to see your personal entries or manage them.
In the inset (at the bottom right), notice the additional choices are added to this user's drop down list, after a set of dashes, for “Course to be taken”.
The “Value” should match what is in “Display”. Please contact your SpEd Forms administrator if you need additional assistance determining the value setting.
