I have select list in my form

I have a select list in my form filled with some options. I’d like to add at the first place a new option something like “Select a option”.

But when I use the function

add(new Option(text, value));

the option is added as last but I need it at the top of the list. Is there any way to get this working like I need ?

Unfortunately it impossible without code modification. By default option is added to the last position.
