Create content type with sub content types

One way to do it would be to add a multiselect nodereference field to the ContentTest content type listing the SubContentTest items.

Another way might be to use one of the node relationship modules: node2node, nodehierarchy, relativity, etc.

(same need for me..)

I'm looking for a similar solution. I'm creating a custom classifieds site. I want one Parent "CLASSIFIEDS" content type. Underneath that as children, I want "REAL ESTATE", "AUTOS" etc - the reason being is that each sub classified type would have a different set of form elements. Any thoughts? Or is the best way to handle it just have .. dunno.. 25 different content types each representing a classifieds category?

I want to have a content type ALBUM that contains an unknown number of TRACKs. Using the station module, but it doesn't provide that capability.

Has anyone of you found a solution for this?

Here's my example...

I want to create an Album list (with some details like artist, year and etc) and on each album there are n tracks.

I guess I can accomplish that by simply creating two content (album and track) and nodereference the track to album. But, is there a way to add a track without leaving the album page and auto-reference the track to the album?

Thanks everyone in advance!
