Hello Artzone, It's my first reply , I'm so excited .....
I try this with you example and it work ..... You could change #mylist with and other 'id' it will work also. It work with a 'id' , but with a 'class' you have to change the code. $(document).ready( function(){ var a = new Array(); $("#mylist").children("option").each(function(x){ test = false; b = a[x] = $(this).val(); for (i=0;i<a.length-1;i++){ if (b ==a[i]) test =true; } if (test) $(this).remove(); }) }); Have a nice day ...
