I have multiple options in a select. I have sorted the options and disabled and hidden the duplicate options with jquery. The code works well in chrome and firefox but in IE
If somebody still faces this issue, here is my solution, it may be helpfull:
$('select.some-list option[id=someId]').attr('disabled', 'disabled').hide();
This hides the option in all browsers and disables if can't hide :). To bring back the option do not forget to enable it:
$('select.some-list option[id=someId]').removeAttr('disabled').show();
