Question

我正在使用bootstrap 4手风琴。我希望所有卡片都折叠起来作为初始状态。我将aria-expanded设置为false，但是所有卡都显示为扩展。

<div id="accordion">
            <!-- ko foreach: $root.Addons() -->
            <div class="card">
                <div class="card-header" id="headingOne">
                    <h5 class="mb-0">
                        <button class="btn btn-link" data-toggle="collapse" aria-expanded="false" data-bind="text:name, attr: { 'data-target': '#collapsible' +  $index(),'aria-controls': 'collapsible' +  $index() }"></button>
                    </h5>
                </div>
                <div data-bind="attr: { id: 'collapsible' + $index() }" class="collapse show" aria-labelledby="headingOne" data-parent="#accordion">
                    <div class="card-body">

                    </div>
                </div>
            </div>
            <!-- /ko -->
        </div>

我做错了什么？

Answer 1

您需要更新处于折叠状态的类。

1）在按钮元素中添加collapsed和类btn btn-link

2）从div元素中的show中删除类collapse show

我已经通过上述更改更新了代码。最初应将手风琴保持在折叠状态。

<div id="accordion">
            <!-- ko foreach: $root.Addons() -->
            <div class="card">
                <div class="card-header" id="headingOne">
                    <h5 class="mb-0">
                        <button class="btn btn-link collapsed" data-toggle="collapse" aria-expanded="false" data-bind="text:name, attr: { 'data-target': '#collapsible' +  $index(),'aria-controls': 'collapsible' +  $index() }"></button>
                    </h5>
                </div>
                <div data-bind="attr: { id: 'collapsible' + $index() }" class="collapse" aria-labelledby="headingOne" data-parent="#accordion">
                    <div class="card-body">
                        Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch.

                    </div>
                </div>

            <!-- /ko -->
        </div>
