drupal 7 module for nodes with views I have a problem to find a right module in drupal to do something that should be simple.

I need my web content out into two columns. Entering a node should have title and description in the center column, and then a right column with related documents. It should be the same type of content.

In a previous work had solved with "views", the result:

The problem to do with "views" it was not working the bread crumbs, nor the search. Neither the menu worked properly (not marked as an asset corresponding point)

Now, I'm working with "panels" to avoid this problem. It allows me to create columns, and embed a view with eg documents. The problem is that if I use a "panel page" does not appear in the search, and if I create a "panel node" I can pass arguments to the view in the right pane.

The question is: Is this right module? Should look for another module? is there another proper way to do this in Drupal?

Excuse my language, I'm Spanish :)

Thank you very much for your help, in another post I have been very useful.
Panels is the right module to control this kind of layout. You should be using the node/%node panel in Page Manager and be overriding that.
http://example.com/admin/structure/pages/nojs/operation/node_view/handlers/node_view_panel_context/content

The documents should be uploaded to the Node during editing. If you are missing a field for Documents create a Documents field in the node Content Type of Field Type file. Allow it to have infinite values.

Return to Page Manager > Content. Add content into the right hand panel (using the gear icon). Choose Node and locate your Field: Documents. Add that.

Add your other content into the centre panel. Your left hand panel can be a block (for example a Menus block).
