javascript - AngularJS - 我需要一个可以同时打开多个面板的 Accordion

Question

我有这个指令JS Fiddle expample由于可以选择一次打开一个面板，我需要修改该行为并为用户提供打开多个面板的选项。

在下面您将看到与我的 JS Fiddle Expamle 上相同的代码

    directive("btstAccordion", function () {
    return {
        restrict: "E",
        transclude: true,
        replace: true,
        scope: {},
        template:
            "<div class='accordion' ng-transclude></div>",
        link: function (scope, element, attrs) {

            // give this element a unique id
            var id = element.attr("id");
            if (!id) {
                id = "btst-acc" + scope.$id;
                element.attr("id", id);
            }

            // set data-parent on accordion-toggle elements
            var arr = element.find(".accordion-toggle");
            for (var i = 0; i < arr.length; i++) {
                $(arr[i]).attr("data-parent", "#" + id);
                $(arr[i]).attr("href", "#" + id + "collapse" + i);
            }
            arr = element.find(".accordion-body");
            $(arr[0]).addClass("in"); // expand first pane
            for (var i = 0; i < arr.length; i++) {
                $(arr[i]).attr("id", id + "collapse" + i);
            }
        },
        controller: function () {}
    };
}).
directive('btstPane', function () {
    return {
        require: "^btstAccordion",
        restrict: "E",
        transclude: true,
        replace: true,
        scope: {
            title: "@",
            category: "=",
            order: "="
        },
        template:
            "<div class='accordion-group' >" +
            "  <div class='accordion-heading'>" +
            "    <a class='accordion-toggle' data-toggle='collapse'> {{category.name}} - </a>" +

            "  </div>" +
            "<div class='accordion-body collapse'>" +
            "  <div class='accordion-inner' ng-transclude></div>" +
            "  </div>" +
            "</div>",
        link: function (scope, element, attrs) {
            scope.$watch("title", function () {
                // NOTE: this requires jQuery (jQLite won't do html)
                var hdr = element.find(".accordion-toggle");
                hdr.html(scope.title);
            });
        }
    };
})

我能做什么？

您只需删除 data-parent属性(DEMO):

//...
// set data-parent on accordion-toggle elements
var arr = element.find(".accordion-toggle");
for (var i = 0; i < arr.length; i++) {
    //$(arr[i]).attr("data-parent", "#" + id);          <------- here
    $(arr[i]).attr("href", "#" + id + "collapse" + i);
}
//...
