In Drupal-6 I have a content type called: Colors with the following fields: title, body and code. Then I have another content type called: Material with the following fields: title, body and color. This color field is a node reference related to the Colors content type.
So far so good.
Now when I create a Material node I can select a color from a select list. And here is my issue: this select list shows the title of the colors nodes. Is there any way to show the code for the node instead of the title. Or better, show the title and the code.
