selected with no value still shows a lign, even with magnet

when using <option>[defaut;magnet=option;ope=html;select]</option>
it shows a <option selected></option> when defaut is empty (defaut="")
how should i do that ? options are populated using mysql with tbs, so i don't have access to data in there before the user chooses one .
i do not want that empty line to show ...

any suggestion ?

Parameter "magnet" is processed after parameter "ope", but in your case,the value is no longer empty avec doing the select.

You can walkaround this problem with something like this:

thx :)
