选择2个子元素和onclick事件

Question

我正在寻找一种在select2中创建子类别的方法，并在其中附加一个点击事件。现在我用这种方式格式化了我的结果：

问题是子类+ http链接只是我实现中select2中的一个元素。它并没有像我想要的那样运作。如何按照Select2功能（输出子类别而不是列表中的项目）的方式执行它？真的有可能吗？

这是我的代码：

    function format2(item) {
        return item.type;
    }

    function format1(item) {
        var list = "<div>";

        $.each(item.elements, function(index,value){
            var url;

            console.log(item.type);

            switch(item.type) {
                case 'Пост':
                    url = value.url;
                    break;
                case 'Пользователь':
                    url = '/id' + value.ID;
                    break;
                case 'Коллекция':
                case 'Тэг':
                case 'Категория':
                    url = '#';
                    break;
            }

            list += "<div>" + "<a href='" + url + "'>" + value.name + "</a>" + "</div>";
        });

        list += "</div>";
        var markup = '<div>' + item.type + '<div>' + list + '</div>' + '</div>';
        return markup;
    }

    $("input#s").select2({
        multiple: true,
        placeholder: "Search for a repository",
        minimumInputLength: 3,
        ajax: {
            url: "<?php echo admin_url( 'admin-ajax.php' ); ?>",
            dataType: 'json',
            quietMillis: 250,
            data: function (term, page) {
                return {
                    action: 'roomble_load_term_posts',
                    search_param: term
                };
            },
            results: function (data, page) {
                var elements = [];

                console.log(data);
                $.each(data, function(index, value) {
                    if ((typeof value.posts != 'undefined') && value.posts.length > 0){
                            elements.push({elements: value.posts, type: "Пост"});
                    }
                    if ((typeof value.tags != 'undefined') && value.tags.length > 0){
                            elements.push({elements: value.tags, type: "Тэг"});
                    }
                    if ((typeof value.collections != 'undefined') && value.collections.length > 0){
                            elements.push({elements: value.collections, type: "Коллекция"});
                    }
                    if ((typeof value.categories != 'undefined') && value.categories.length > 0){
                            elements.push({elements: value.categories, type: "Категория"});
                    }
                    if ((typeof value.users != 'undefined') && value.users.length > 0){
                            elements.push({elements: value.users, type: "Пользователь"});
                    }
                });

                return {
                    results: elements
                };
            }
        },
        formatResult: format1,
        formatSelection: format2,
        dropdownCssClass: "bigdrop",
        escapeMarkup: function (m) { return m; } // we do not want to escape markup since we are displaying html in results
    }).on("select2-selecting", function(e) {
        console.log(e);
    });
