Styling part of the OPTION text
But you could always create a Custom select box. Refer the jsFiddle below,
JSFiddle for multi colored selectbox options
// Insert a list item into the unordered list for each select option
for (var i = 0; i < numberOfOptions; i++) {
$('<li />', {
html: $this.children('option').eq(i).text()
.split(' ').join(' <span style="color:red">'),
rel: $this.children('option').eq(i).val()
}).appendTo($list);
}
Nope. options are styled in a way native to the platform, and styling only a part of one doesn't work. (It usually wouldn't be a particularly good idea either.)
Or you could do it with Bootstrap Drop Downs plus a couple lines of Javascript.
Here is the Bootstrap example with a slight alteration plus a 'lil Javascript:
$(function() {
$('#my-select').find('li').click(function() {
$('#selected').html($(this).html());
});
