Entity Overlay

In Drupal you can use a reference field. This gives a link to this reference, or you can show (a part of) this reference. This module will, when clicking on the reference link, display the content as a pop-up window. Useful. You remain on the original page.

In the display you will get opportunities to ...

In the display you select eg "Label Overlay" showing the reference as a link.

If you click on the link a popup appears.

Or you use the rendered entity and shows a portion of the reference content.

You can see the teaser view here. Clicking on the link will take you to the full view of the reference node. You can do this with any reference (taxonomy, users, content, ..)
