Good evening Marion,
Thank you for reaching out to us.
I would love to help you with this topic.
Is it possible to display the featured image above the title in list view and in single event view.
The short answer is yes. You can customize any view you like by doing a template (view) override.
You might want to read our Themer’s guide to get a sense of how that works.
Basically you can open up the files of the list view and move around the sections to your liking.
Once that is done, you upload the modified file back under the /tribe-events/ folder of your WordPress theme.
Let me know how that goes.
Best regards,
Geoff B.
