jQueryUI: Autocomplete

jQueryUI: Autocomplete

I want to insert 2 values in the same row in the autosuggest item. I also want to add a tab between these 2 values and grey out the 2nd value. Is that possible using the Autocomplete plugin? Below is the code which I am using..please see the highlighted line where i am trying to insert the second value..it appears in the dropdown of suggestions but there is no whitespace between 1st and 2nd value(also how do i change the font color for the sencond value?)

$('#searchtext').autocomplete({
            source: function(request, response) {
                $.ajax({
                    url: "Search",
                    dataType: "json",
                    data: {
                        term: request.term
                    },
                    success: function(data) {
                        response($.map(data, function(item) {
                            return {
                                value: item.Value + "               " + item.Type
                            }
                        }));
                    }
                }); // ajax close
            },
            minLength: 2

        });
