Custom fields on a structure or section archive page I have a section (or structure, works both) for "events". On the archive template (see image below) I want to add a custom image in the header. The administrator needs to be able to upload the header image.

 

In a section/structure there is no dedicated page, so I cannot assign custom fields to it. How do I tackle this problem?
What you could do is make a "Global" Which sets the header image. You could name the global something like "Event Page Fields" or something like that so its clear for your administrator where to look.

The other option is creating a Single page and load all the structure items via the template there. This way you can add the image field to that single.
