Hello, does anyone know if it's possible to change the display of the list items depending on the record type? For example, if the record type is an Invoice, the custom field should show the internalid of the list item #1, #2, and #3, but if it's a Bill, the list should show #4, $5, and #6 for example.

I’m afraid the only way to do this is to create a custom field via script, get all possible values in the order you want them displayed via script, and add them to the field. There’s no middle ground where you can re-arrange the ones that are given to you natively.

thanks so much @mattdahse, i'll give it a try
