Format Select2 dropdown results having json

I am using select2 dropdown control to display list of facilities e.g facility A,B,C...etc. along with its location details. I am looking for following output,

Currently I can display "facility name", but would like to display City and State from my json objects. How can I format my results to display them as above html format? Here's my code so far.

<input type="hidden" id="ddlFacility" style="width:100%" />

$("#ddlFacility").select2({
        placeholder: "Select a Facility",
        ajax: {
            url: "my url",
            dataType: 'json',
            type: "GET",
            quietMillis: 50,
            data: function ( term ) { return { term: term }; },
            results: function (data) {
                return {
                    results: $.map(data, function (item) {
                        return { text: item.FacilityName, id: item.FacilityId }
                    })
                };
            }
        }
    });

in your select2 options pass a function something like this and style the classes however you need

...
placeholder: "Select a Facility",
    formatResult: function(item)
    { 
         return '<div class="facility">' + item.text + '</div><span class="city">' + item.city + '</span></div>';
    },
 ...

you may need your .map function to include Facilityname and City values in addition to id and text.

If you want the selected value to look the same, use the same function for the formatSelection option
