If you define a custom field of type Selection form, you can add both the field containing the code () and the field containing the name or description of the selection form (
) to a custom tab. In the code field, use
to display the selection form (for example, Parts); the field containing the name or description of the selection form cannot be changed. Each of them can individually be placed on the tab (see Custom tabs, Filling Custom tab by using the Field Chooser).
