I have a list of comma separated values "1,2,3,4"
I have a multiselect list with options that match those values, I am cycling through my list and selecting each option individually(see below)

```
jQuery.each(selectedVals, function(index, item){
     jQuery("option[value='"+item+"']", jQuery("#manage select")).attr('selected', true);
});

```

The multiselect list and the values could be in the hundreds so the performance on older browsers is slow when cycling through and selecting. Is there a quicker way to accomplish this? Some how selecting them all at once?
