I'm trying to custom order for a field "Country" .
I did a mapping with the field "Country" and " Country Order" like below:
Country Country Order
After loading, i use sort by expression in the listbox:
But the problem is : when i select a value in the listbox, the value selected goes to the end of the list. (i had some similar problem with the value selected goes to the top of the list ), as result, impossible to sort by expression.
I unchecked the box "State", but it does not work.
