Generic parent child custom post type is simply a plugin that gives an example of how to create two custom post types where one is the parent and you can assign any number child posts to it.
The two post types are called Parents and Children. As an example you could call them Car Dealership and Cars and assign a bunch of cars to a dealership.
There is an example template file included which displays the parent post as well as a list of all the children posts assigned to it.

Requires WordPress 3.0 and PHP 5.

Designed to display the Parent, Child, and Grandchild hierarchy in the most straightforward way out of the box.
This plugin will provide a widget that locks the Parent page as the widget title.
If this is a child of the top parent, the widget will display the Parent as the title of the widget and a ul of links for all siblings of the current page.
If this is a grandchild of the top parent, the Widget will display the same as the scenario above with the addition of a sub ul of all siblings of this grandchild.
Test it out, if it doesn’t work like you want out of the box, this plugin isn’t for you.
