如何控制 Bootstrap 4 中的可折叠内容?

例如,这个导航栏如下:

我想控制这个演示的状态。
具体来说,
在状态2中,我希望搜索通知不是换行符,仍然是一行。
在状态 3 中,我希望 search inform 和 navbar-brand 不消失,ul 菜单只消失。

怎么做?

代码:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<meta http-equiv="x-ua-compatible" content="ie=edge">

<link href="https://cdn.bootcss.com/bootstrap/4.0.0-alpha.2/css/bootstrap.min.css" rel="stylesheet">
<link href="https://cdn.bootcss.com/tether/1.3.2/css/tether.min.css" rel="stylesheet">
</head>
<body>

<nav class="navbar navbar-fixed-top navbar-light bg-faded">
<button class="navbar-toggler hidden-sm-up" type="button" data-toggle="collapse" data-target="#exCollapsingNavbar2">
&#9776;
</button>
<div class="collapse navbar-toggleable-xs" id="exCollapsingNavbar2">
<a class="navbar-brand" href="#">Responsive navbar</a>
<ul class="nav navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
</ul>
<form class="form-inline pull-xs-right">
<input class="form-control" type="text" placeholder="Search">
<button class="btn btn-success-outline" type="submit">Search</button>
</form>
</div>
</nav>

</html>

最佳答案

docs解释这是如何工作的。从 collapse 中取出您不需要的响应式可切换菜单中的任何内容。您可能需要调整 CSS 以减小表单的宽度。

<nav class="navbar navbar-fixed-top navbar-light bg-faded">
<button class="navbar-toggler hidden-md-up" type="button" data-toggle="collapse" data-target="#exCollapsingNavbar2">
&#9776;
</button>
<a class="navbar-brand" href="#">Responsive navbar</a>
<form class="form-inline pull-xs-right">
<input class="form-control" type="text" placeholder="Search">
<button class="btn btn-success-outline" type="submit">Search</button>
</form>
<div class="collapse pull-xs-left navbar-toggleable-sm" id="exCollapsingNavbar2">

<ul class="nav navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
