How to assign a content type to a specific block in Drupal 7?

Question

I want some content types to open in a block in the sidebar, not in the main content area, ideally without refreshing the main content area.

How can this be done in Drupal 7? I was thinking of using Panels but have not found the solution yet.

Answer 1

So the view on the left contains multiple node items. What must be edited in the left view by a user? And the column right shows all the information of the chosen node?
