Please take this code if any of it will be useful to you - the whole point of this is to help people start using the preview panel to help their content authors get a clear indication of what their content will look like (beyond just pages themselves).
Check out the official documentation about the preview panel for additional context.
Basically, if your data has a visual representation you absolutely should be providing a CMS preview for it. It's dead easy and gives a lot of value.
This is a fully functional demonstration as shown in my lightning talk at Stripecon EU 2022. It includes fixtures for all of the content I used in that demonstration.
- clone the repo
composer install- Perform a dev/build - this will pull in all of the fixtures. DO NOT do a second dev/build at any point.
I have created a module which goes hand-in-hand with this talk - it provides a preview of data objects from within a gridfield - no need to click through to the edit form for each record.

- Preview a PDF which is generated on-the-fly (Pdf Admin -> PDF Templates)
