Bootstrap下拉列表消失得太快

Question

I am using a Bootstrap dropdown menu. 我正在使用Bootstrap下拉菜单。 It all worked fine untill i made some changes I can't undo anymore. 一切正常，直到我做了一些我无法撤消的更改。 When I go to my website on a mobile phone the dropdown disappaers after 1-2 seconds. 当我通过手机访问网站时，下拉菜单会在1-2秒后消失。 If I use the original bootstrap it works fine but when I use my own it doesn't. 如果我使用原始的引导程序，则可以正常工作，但是当我使用自己的引导程序时，则不能。 I searched everywhere for the answer but I haven't found a solution. 我在各处搜索了答案，但没有找到解决方案。 I also made a JS Fiddle to show you. 我还制作了一个JS小提琴来向您展示。

<body>
    <nav class="navbar navbar-inverse">
        <div class="container-fluid">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#inverseNavbar1">
                  <span class="sr-only"></span>
                  <span class="icon-bar"></span>
                  <span class="icon-bar"></span>
                  <span class="icon-bar"></span>
                </button>
                <a class="navbar-brand" href="">Home</a>
            </div>
            <div class="collapse navbar-collapse" id="inverseNavbar1">
                <ul class="nav navbar-nav">
                    <li class="active"><a href="info">Info<span class="sr-only"></span></a>
                    </li>
                    <li class="active"><a href="foto">Foto's<span class="sr-only"></span></a>
                    </li>
                </ul>
                <ul class="nav navbar-nav navbar-right">
                    <li><a href="beschikbaarheid">Beschikbaarheid</a>
                    </li>
                    <li><a href="prijzen">Prijzen</a>
                    </li>
                    <li><a href="contact">Contact</a>
                    </li>
                </ul>
            </div>
        </div>
    </nav>

Thanks in advance 提前致谢

I suspect that at least one rule is missing from the bootstrap.css. 我怀疑bootstrap.css中至少缺少一条规则。 If you add: 如果添加：

.collapse.in {        
      display: block;       
}

You get the functionallity back but the animation does not look good. 您恢复了功能，但动画效果不佳。

In bootstrap the navbar when collapsed will have classes 在引导中，导航栏在折叠时将具有类

<div class="navbar-collapse collapse"></div>

During animation it will get: 在动画期间它将得到：

<div class="navbar-collapse collapsing" aria-expanded="true" style="height:SOMEHEIGHT"></div>

And after, when visible 之后，当可见时

<div class="navbar-collapse collaps in" aria-expanded="true"></div>

Without the css rule, when the animation of the menu is finished the menu was not shown because there exist a rule that hides all items with class collapse: 如果没有css规则，则当菜单的动画完成时，菜单不会显示，因为存在一个规则，该规则会隐藏所有具有类折叠的项：

.collapse {
  display: none
}
