A UDF (User Defined Field) is a feature of OpenDocMan that allows the administrator to add custom meta-data fields to all documents.
To Add UDF's:
Click on Admin→UDF→Add
Enter the Internal Name (5 chars): ex. col2
Enter the Display Name: Color 2
Select “Select List”
Click “Add UDF”
Now that the UDF is added, the Select List UDF needs some values for the users to pick from:
Click on your new UDF in the admin menu (ex. “col2”)
New Value: “Blue”
Click Update
New Value: “Red”
Click Update
Now “edit” or “add” a file and you should see a new dropdown list with Blue/Red as options for each file.
Radio items are done the same way as Select lists. The Text Field UDF just provides a blank text box for each file.
