Question

我一直在努力不使用崩溃动画。单击切换按钮时动画不起作用。 1秒后，整个菜单显示没有动画，类似于jQuery函数show()

这是我的代码：

<nav class="col-md-12 navbar navbar-static-top" role="navigation">
  <button type="button" data-target="#navbarCollapse" data-toggle="collapse" class="navbar-toggle">
    <span class="sr-only">Toggle navigation</span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
  </button>
  <div class="container">
    <div id="navbarCollapse" class="collapse navbar-collapse">
      <ul class="nav nav-justified main-nav">
        <li class="menu-item current-menu-item"><a href="#">Home</a></li>
        <li class="menu-item submenu"><a href="#">Submenu</a>
          <ul>
            <li>test</li>
            <li>test</li>
            <li>test</li>
          </ul>
        </li>
      </ul>
    </div>
  </div>
</nav>

任何想法为什么会发生？

以下是您的代码的mvce以及适用的库 - 根据Bootstrap规范，HTML的结构存在几个问题

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.css" rel="stylesheet" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/js/bootstrap.min.js"></script>


<nav class="navbar navbar-default">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" aria-expanded="false"
        data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" >
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">Brand</a>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li class="active"><a href="#">Home <span class="sr-only">(current)</span></a></li>
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button"
             aria-haspopup="true" aria-expanded="false">
            Submenu <span class="caret"></span>
          </a>
          <ul class="dropdown-menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
          </ul>
        </li>
      </ul>
   </div>
   
   
  </div>
</nav>

这是一个简单的工作导航栏，取自Bootstrap's Docs on Collapse：

public partial class TableRow : ViewCell
{
    public static readonly BindableProperty TextProperty =
        BindableProperty.Create("Text", typeof(string), typeof(TableRow), null);

    public string Text
    {
        get => (string)GetValue(TextProperty);
        set
        {
            SetValue(TextProperty, value);

            lblValue.Text = value;
        }
    }

我建议从文档中的标准模板开始，然后根据您的特定用例进行调整。
