Hi Jerome,
thanks for your answer,
Now i use for both value and option value of the DDL the same string that is the complete google product category string.
I know that this solution is non so good, but is the only one I know.
If is possible I can use an extra DB table with 2 columns (id and string_value), and I can use this table to gnerate html slelect element, but i don't know how to mke this solution.
First thing, is possible ?
If it is possible, how i can implement this solutions ?
For the other problems derived by the last update (2.3.1), which can be the possible solutions ?
Many Thanks, regards
Luca
