选择2时的框模态

Question

我正在尝试调整select2，如果显示此

    $('#postadcity').select2({
        ajax: {
            url: ajaxurl + '?action=searchCityFromCountry',
            dataType: 'json',
            delay: 50,
            data: function (params) {
                var query = {
                    q: params.term, /* search term */
                    page: params.page
                };

                return query;
            },
            processResults: function (data, params) {
                /*
                 // parse the results into the format expected by Select2
                 // since we are using custom formatting functions we do not need to
                 // alter the remote JSON data, except to indicate that infinite
                 // scrolling can be used
                 */
                params.page = params.page || 1;

                return {
                    results: data.items,
                    pagination: {
                        more: (params.page * 10) < data.totalEntries
                    }
                };
            },
            cache: true
        },
        escapeMarkup: function (markup) { return markup; }, /* let our custom formatter work */
        minimumInputLength: 2,
        templateResult: function (data) {
            return data.text;
        },
        templateSelection: function (data, container) {
            return data.text;
        }
    });

我希望它像在此页面上的首页上搜索城市一样，以找到开放模式，为您提供不喜欢2型字符的城市来查找城市 https://www.masrvape.com/
