Jquery multiselect to slow for 1300 records

Question

I implemented this solution to get a MultiSelect DropDownList Box: http://www.erichynds.com/examples/jquery-ui-multiselect-widget/demos/#filter

However, it is to slow. Why do I need this? The user has to be able to select multiple medications. The total medication are 1300.

Should I have them filter the search box before populating it? Or is there a way I can improve the speed?

I am using MVC3 jquery
