I am trying to create a checkbox list from content to use as property on my document type.

In the olden days (ver. 6) you could create a checkbox list by creating a new data type, select "Ultimate picker" and then set the parent node id. Then you could just add that data type to the doc type.

I have the following content setup:

-- Departments

---- Dep.1

---- Dep. 2

---- Dep. 3

-- Persons

---- Person 1

---- Person 2

---- Person 3

Each person can be in multiple department (hence the checkbox list).

How would I go about creating this in version 7 with no Ultimate Picker? Or is there an even better way to do this now?

Thanks...
