AngularJS-我需要一个手风琴，可以同时打开多个面板

Question

I have this directive JS Fiddle expample with the option to open one panel at the time, I need to modify that behavior and give to the user the option to have multiple panels open.

Here below you will see the code which is the same on my JS Fiddle Expamle

    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);
            });
        }
    };
})

What can I do ?

Answer 1

You just need to remove the data-parent attribute ( 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);
}
//...

This question IMO is a perfect example of not using angular well. I would suggest removing the entire directive, and jQuery, as they are unnecessary for a simple accordion (ie angular is perfect for this type of ui). Here is an updated version:

http://jsfiddle.net/MTKp7/131/

Now I have left it as verbose as possible so that you can make the choice about how you should abstract it (by using ng-repeat mixed with ng-include for example). I have also left the dependencies on the libraries so that the styles are preserved, but these are also not difficult to grab.

Here is the basic example of how you could create this functionality. The div structure and classes were only left to match the jQuery object.

<div class="accordion" ng-controller="AccordionCtrl">
    <div class="accordion-group">
        <div class="accordion-heading">
            <a class="accordion-toggle" ng-click="toggle('a')">test</a>
        </div>
        <div class="accordion-body">
            <div class="accordion-inner" ng-show="show.a">
                <div>Anim pariatur cliche reprehenderit, enim eiusmod high life 
            accusamus terry richardson ad squid. 3 wolf moon officia aute,

            </div>
        </div>
    </div>
</div>

And for toggling:

$scope.toggle = function(index) {
    $scope.show[index] = !$scope.show[index];
};
