问题描述

我正在使用 bootstrap v5，但遇到以下崩溃问题。问题是，当单击列表时，该列表会立即出现并消失，而不是保持打开状态。我一定遗漏了一些非常简单的东西，因为我已经走到了一半，那是暂时打开的！ :)

                <div id="filters_col">
                    <a data-toggle="collapse" href="#collapseFilters" aria-expanded="false" aria-controls="collapseFilters" id="filters_col_bt">Filters </a>
                    <div class="collapse" id="collapseFilters">
                        <div class="filter_type">
                            <h6>Duration</h6>
                            <input type="text" id="range" name="range" value="">
                        </div>
                        <div class="filter_type">
                            <h6>Review score</h6>
                            <ul>
                                <li>
                                    <label>Superb: 9+ (77)</label>
                                    <input type="checkBox" class="js-switch" checked>
                                </li>
                                <li>
                                    <label>Very good: 8+ (552)</label>
                                    <input type="checkBox" class="js-switch">
                                </li>
                               
                            </ul>
                        </div>
                        <div class="filter_type">
                            <h6>Type</h6>
                            <ul>
                                <li>
                                    <label>Cocktails Bar (77)</label>
                                    <input type="checkBox" class="js-switch" checked>
                                </li>
                                <li>
                                    <label>Pub (552)</label>
                                    <input type="checkBox" class="js-switch">
                                </li>
                            </ul>
                        </div>
                    </div>
                    <!--End collapse -->
                </div>

解决方法

变化：

data-toggle="collapse"

到：

data-bs-toggle="collapse"
