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?

Answer 2

you can add blocks to the specific content types and place these blocks in an region (such as sidebar). In the template you can add this region. And what do you mean with "without refreshing", do you want the content to be updated client side?
