I'd like to do something like the following:
Option_container option_instance_1 option_instance_2 option_instance_3
(Basically a custom new class that holds options whereas all options are contained in option_container).
Now I'd like to have a type that is like enum but always lets the user chose the elements stored belov option_container.
Enum doesn't cut it as I need to have the same options for different classes which would need to have the options reentered all the time (additionally, I need to store some more data per option than just a name).

If you're up for it, I'm quite certain you can create your own datatypes.
Go to /kerner/classes/datatypes/ and you'll see folders for all the datatypes, including enum.
See the following tutorial about making your ownhttp://ez.no/sdk/tutorials/view/datatypes

You can do this with a custom module and a new datatype.The module would handle the creation of the option lists and the datatype would refer to one your option items making it easy to use in multiple classes.
I would recommend looking at either the option or enum datatype for example code.

I was kinda hoping I could do without implementing a new datatype but hey, I gotta try it at one time (just not today ;-).
I don't think I need a module for it though as I simply want it to display all the 1st level children of a given node.
I've eben been thinking of just abusing the multi category feature for linkage (to link employes to projects for one).
