ui multiselect add class to li when selected?

Question

is there any option to add class to the selected li i.e the options selected, if so how cani add and get the values?

close: function(event, ui){
var selectedValues = $('#VendorNum').val();
 $('.ui-multiselect-checkboxes li').each(function(){
    if($(this).is(":selected")){
    alert(selectedValues);   
    }
 });  

}

The alert is not working here

Answer 1

":selected" selector may be used only on "option" elements, not "li".

Try this code:

click: function(event, ui){
 $('.ui-multiselect-checkboxes li').removeClass("highlight");
 $(this).addClass("highlight");  
},
close: function(event, ui){
 alert($('.ui-multiselect-checkboxes').multiselect('getChecked').join(", "));
}
