Hello Markus, Your desired scenario can be achieved with the out of the box functionality that Sitefinity provides. Please check the attached pictures, where you can find all the necessary setting that you need to do. Keep in mind that the settings for the create view and edit view are separate. I hope that this information helps. Regards, Kaloyan Telerik
As for your question I have created a video that demonstrates the required steps for configuring the sections. You can view the video here.
