Side Panel Data Widget / show item record details

I have some ideas how to use it but I need some start how to do:

  1. show item record details instead in Modular pop up
  • I want to open the record details in the side panel
  1. Show as Comment Panel
  • when open the record details I want to use the side panel for comments (create a commenting system in Tadabase)
  • comments should be record related

Anybody done this ?
