The drop down menu "Modify course elements" helps you to delete, move or copy course elements. Your action will affect the currently marked course elements as well as all subordinated ones.
In the Move / Copy overlay select the position you wish to insert the new element into, and choose the corresponding icon: the upward arrow to insert the new element above, the downward arrow to insert below, and the bent arrow to insert as child element.
It is possible as well to move course elements using „Drag&Drop“ in the course structure to the left.
Modifications such as deleting, moving, copying course elements have to be published later on in order to be effective. If you have not published a deleted course element it can still be recovered.
Copying course elements is advisable if you plan to offer team work in groups and want to reuse the same structure.
