Good evening Bart and welcome back!
Thank you for reaching out to us.
I would love to help you with this topic.
The short answer is yes. You can achieve this.
There are a couple of ways to go about this.
Ideally you would want to use a proper page template that has a conditional to differentiate between the full calendar page and the single event page.
You might want to read our Themer’s guide to get a sense of how that works.
Another way to achieve this is the following:
- Find a page template that has a sidebar by trying different settings for Events Template under Events -> Settings -> Display
- Using CSS hide the sidebar from the main calendar views
Let me know if that helps.
Have a great day!
