To add a student/child within an optional group we will first have to select the Children Groups tab > Select the Optional Group.
After this group has been selected, the children in the optional group will be displayed in the central part. To add a new child, click on the green "Add child" button at the top.
Once you have clicked, a pop-up window appears in the middle of the screen where you will be able to select the children you want to add to the selected optional group.
