Table user-defined fields contain a list of similar items from which a user may select one or more items. As part of the process of creating a new user-defined field of this type, you should add the items to the table.
In the left navigation pane, click Administration and select Set Up User-Defined Fields.
To search for a field, enter all or part of a field name in the search box and click the search icon.
All matching fields in the list are highlighted, and the number of matching fields is displayed.
Select the table user-defined field, and click Items.
The Set Up Items dialog box opens.
Click Add Item.
Type a name for the item, and specify the other properties of the item.
If you set the item to hidden, you can hide it from the Available Values list by clearing the Show hidden items option.
