Drupal 7 Node inside of node in a form

I am trying to do something like this:

• Project: Name, Due Date
  • Mileston开发者_JAVA百科e: Due Date, Project
    • Task: Milestone, Title, Priority...etc

Is it possible to create a project with milestones and tasks all in one form and create all the nodes at once?

---

in this case drupal work with this as 1 node... you can create one node with multiple form..

use CCK with field group to group your node forms... you can create

Group for milestone form

Group for Task form

ALL of this is regarded as one node.. but i don't think u can insert more than one node in the same form
