Dear all,

I am new to Drupal, not familiar with PhP. I need to create some hierarchical content. Think of two levels. There will be multiple children contents associated with a parent content. When view the contents, the sub-contents need to be separated by the parent content. Of course, the parent and children contents are in different types. I thought of nodereference field. Should I use the nodereference on the parent node or the children content? For redundancy concern, I should use it on the children content. However, how can I view the children contents when view the parent content?

Thanks a lot.
