如何使用Bootstrap折疊避免一次打開多個元素

Question

我正在使用Bootstrap 3並且無法弄清楚如何使用它們的折疊功能一次只允許打開一個元素。

目前，單擊鏈接的圖像會按預期顯示折疊的div。 但是，如果單擊其他鏈接圖像，則相應的div也會在不關閉第一個圖像的情況下顯示。

我在這里錯過了什么？

這是我的HTML：

<section id="employees" class="text-center">
        <ul id="employee_list" class="list-unstyled list-inline">

            <li class="employee_info">
                <a data-toggle="collapse" data-parent="#employee_list" data-target="#collapse1"><img src="/media/cache/5a/a3/5aa3c3ab6d4af27b6efe20a8b3d9b119.jpg" width="175" height="175" class="img-circle" alt="Charles"></a>
                <h2>Charles<br><small>Owner</small></h2>
            </li>

            <li class="employee_info">
                <a data-toggle="collapse" data-parent="#employee_list" data-target="#collapse4"><img src="/media/cache/0a/a1/0aa14aaa5f95ed5eb86bb0a81fec5dd6.jpg" width="175" height="175" class="img-circle" alt="Kathleen"></a>
                <h2>Kathleen<br><small>Design Consultant</small></h2>
            </li>

            <li class="employee_info">
                <a data-toggle="collapse" data-parent="#employee_list" data-target="#collapse2"><img src="/media/cache/f1/ad/f1adc6187d0209e5ff14ed43118ca6b8.jpg" width="175" height="175" class="img-circle" alt="Carlos"></a>

            <li class="employee_info">

                <h2>Phil<br><small>Project Manager</small></h2>

        </ul>

Answer 1

Bootstrap不支持開箱即用的內容。 您需要做的是聽取引導觸發器然后折疊其他觸發器的“show.bs.collapse”事件。

$(".employee-collapse").on("show.bs.collapse", function(e) {
  $(".employee-collapse").not(e.target).each(function(i, el){
    if ($(el).is(":visible"))
      $(el).collapse('hide');
  });
});

你會看到我將.employee-collapse類添加到元素中只是為了更具體。

<section id="employees" class="text-center">
        <ul id="employee_list" class="list-unstyled list-inline">

            <li class="employee_info">
