Well, I ended up going jQuery on it (converting all the "disabled" options
into optgroups - cross-browser disabling):
$('#ProductCategoryId option').each( function(idx) {
thisIndent = $(this).text().split('—').length - 1;
nextIndent = $(this).next().text().split('—').length - 1;
if (nextIndent > thisIndent) {
$(this).replaceWith('<optgroup label="' + $(this).text() + '"/>');
}
});
