折りたたみ可能なnavbar
を作成したいと思います。すべてが機能しますが、nav
アイテムは本来のように互いに積み重ねられません。それらは水平方向に隣り合っています。
コード:
<nav class="navbar navbar-light bg-faded" role="navigation">
<button class="navbar-toggler hidden-sm-up" type="button" data-toggle="collapse" data-target="#collapsing-navbar">
☰
</button>
<div class="collapse navbar-toggleable-xs" id="collapsing-navbar">
<a class="navbar-brand" href="/">Logo</a>
<ul class="nav navbar-nav">
<li class="nav-item">
<a href="/messages" class="nav-link">Messages</a>
</li>
<li class="nav-item">
<a href="/logout" class="nav-link">Logout</a>
</li>
</ul>
</div>
</nav>
スクリーンショット:
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">Navbar</a>
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<ul class="navbar-nav mr-auto">
<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="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<input class="form-control mr-sm-2" type="text" placeholder="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
</div>
</nav>
このCSSオーバーライドを使用すると簡単に実行できるようです。
@media(max-width:768px) {
.navbar .navbar-nav>.nav-item {
float: none;
margin-left: .1rem;
}
.navbar .navbar-nav {
float:none !important;
}
.navbar .collapse.in, .navbar .collapsing {
clear:both;
}
}

BS4 alpha 6以降、余分なCSSは不要になりました。 navbarマークアップが変更されました。 http://www.codeply.com/go/0OMz6nfPLr
Bootstrap 4 Alpha 5以降、collapse
プラグインを活用できます。
