Меню не будет разрушаться при нажатии на другие пункты

Question

Я пытаюсь воспроизвести это на своем собственном веб-сайте: https://www.bootply.com/bootply/WIu8eya2dQ#

Вот код:

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">
  <div class="list-group panel">
      <a href="#menu1" class="list-group-item" data-toggle="collapse" data-parent="#sidebar">Item 1 <i class="fa fa-caret-down"></i></a>
      <div class="collapse" id="menu1">
          <a href="#menu1sub1" class="list-group-item" data-toggle="collapse">Subitem 1 <i class="fa fa-caret-down"></i></a>
          <div class="collapse" id="menu1sub1">
              <a href="#" class="list-group-item" data-parent="#menu1sub1">Subitem 1 a</a>
              <a href="#" class="list-group-item" data-parent="#menu1sub1">Subitem 2 b</a>
              <a href="#menu1sub1sub1" class="list-group-item" data-toggle="collapse">Subitem 3 c <i class="fa fa-caret-down"></i></a>
              <div class="collapse" id="menu1sub1sub1">
                  <a href="#" class="list-group-item">Subitem 3 c - item 1</a>
                  <a href="#" class="list-group-item">Subitem 3 c - item 2</a>
              </div>
              <a href="#" class="list-group-item" data-parent="#menu1sub1">Subitem 4 d</a>
              <a href="#menu1sub1sub2" class="list-group-item" data-toggle="collapse">Subitem 5 e <i class="fa fa-caret-down"></i></a>
              <div class="collapse" id="menu1sub1sub2">
                  <a href="#" class="list-group-item" data-parent="#menu1sub1sub2">Subitem 5 e.1</a>
                  <a href="#" class="list-group-item" data-parent="#menu1sub1sub2">Subitem 5 e.2</a>
              </div>
          </div>
          <a href="#" class="list-group-item" data-parent="#menu1">Subitem 2</a>
          <a href="#" class="list-group-item" data-parent="#menu1">Subitem 3</a>
      </div>
      <a href="#" class="list-group-item" data-parent="#sidebar">Item 2</a>
      <a href="#menu3" class="list-group-item" data-toggle="collapse" data-parent="#sidebar">Item 3 <i class="fa fa-caret-down"></i></a>
      <div class="collapse" id="menu3">
          <a href="#" class="list-group-item" data-parent="#menu3">3.1</a>
          <a href="#menu3sub2" class="list-group-item" data-toggle="collapse">3.2 <i class="fa fa-caret-down"></i></a>
          <div class="collapse" id="menu3sub2">
              <a href="#" class="list-group-item" data-parent="#menu3sub2">3.2 a</a>
              <a href="#" class="list-group-item" data-parent="#menu3sub2">3.2 b</a>
              <a href="#" class="list-group-item" data-parent="#menu3sub2">3.2 c</a>
          </div>
          <a href="#" class="list-group-item" data-parent="#menu3">3.3</a>
      </div>
      <a href="#" class="list-group-item" data-parent="#sidebar">Item 4</a>
      <a href="#" class="list-group-item" data-parent="#sidebar">Item 5</a>
  </div>
<script src="/jquery/jquery-2.2.4.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js"></script>

Это работает хорошо, но по какой-то причине, когда я расходую товаруже развернутые не разрушаются.

Answer 1

Пример, который вы показываете, относится к Bootstrap 3, а не к Bootstrap 4.

Для поведения аккордеона в Bootstrap 4 следует установить data-parent в элементе collapse вместо элемента, который являетсяпереключение коллапса (data-toggle="collapse").

<div class="list-group" id="sidebar">
    <a href="#menu1" class="list-group-item" data-toggle="collapse">Item 1 <i class="fa fa-caret-down"></i></a>
    <div class="collapse" id="menu1" data-parent="#sidebar">
        <a href="#menu1sub1" class="list-group-item" data-toggle="collapse">Subitem 1 <i class="fa fa-caret-down"></i></a>
        <div class="collapse" id="menu1sub1" data-parent="#menu1sub1">
            <a href="#" class="list-group-item">Subitem 1 a</a>
            <a href="#" class="list-group-item">Subitem 2 b</a>
            <a href="#menu1sub1sub1" class="list-group-item" data-toggle="collapse">Subitem 3 c <i class="fa fa-caret-down"></i></a>
            <div class="collapse" id="menu1sub1sub1">
                <a href="#" class="list-group-item">Subitem 3 c - item 1</a>
                <a href="#" class="list-group-item">Subitem 3 c - item 2</a>
            </div>
            <a href="#" class="list-group-item" data-parent="#menu1sub1">Subitem 4 d</a>
            <a href="#menu1sub1sub2" class="list-group-item" data-toggle="collapse">Subitem 5 e <i class="fa fa-caret-down"></i></a>
            <div class="collapse" id="menu1sub1sub2" data-parent="#menu1sub1sub2">
                <a href="#" class="list-group-item">Subitem 5 e.1</a>
                <a href="#" class="list-group-item">Subitem 5 e.2</a>
            </div>
        </div>
        <a href="#" class="list-group-item" data-parent="#menu1">Subitem 2</a>
        <a href="#" class="list-group-item" data-parent="#menu1">Subitem 3</a>
    </div>
    <a href="#" class="list-group-item" data-parent="#sidebar">Item 2</a>
    <a href="#menu3" class="list-group-item" data-toggle="collapse">Item 3 <i class="fa fa-caret-down"></i></a>
    <div class="collapse" id="menu3"  data-parent="#sidebar">
        <a href="#" class="list-group-item">3.1</a>
        <a href="#menu3sub2" class="list-group-item" data-toggle="collapse">3.2 <i class="fa fa-caret-down"></i></a>
        <div class="collapse" id="menu3sub2" data-parent="#menu3">
            <a href="#" class="list-group-item">3.2 a</a>
            <a href="#" class="list-group-item">3.2 b</a>
            <a href="#" class="list-group-item">3.2 c</a>
        </div>
        <a href="#" class="list-group-item" data-parent="#menu3">3.3</a>
    </div>
    <a href="#" class="list-group-item" data-parent="#sidebar">Item 4</a>
    <a href="#" class="list-group-item" data-parent="#sidebar">Item 5</a>
</div>
