If you have a SELECT statement named "myselect" using the following
var opt = new Option('text of option','value of option'); opt.style.color = 'red'; myselect.options = opt;
it will create an option, subscript 1, coloured red.
However, if you want to change the font attributes you have to do this on the select statement itself:
myselect.style.fontFamily = 'Courier';
Note that the style names in CSS are converted to camelCase, thus font-family becomes fontFamily.
