Here is actually an example of all the sub-components consisted of within a responsive light-themed navbar that instantly collapses at the
md
<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 class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
</div>
</nav>
The
.navbar-brand
<!-- As a link -->
<nav class="navbar navbar-light bg-faded">
<a class="navbar-brand" href="#">Navbar</a>
</nav>
<!-- As a heading -->
<nav class="navbar navbar-light bg-faded">
<h1 class="navbar-brand mb-0">Navbar</h1>
</nav>
Adding images to the
.navbar-brand
<!-- Just an image -->
<nav class="navbar navbar-light bg-faded">

</a>
</nav>
Navbar site navigation links based on
.nav
Active forms-- with
.active
.nav-link
.nav-item
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>

</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
</div>
</nav>
And due to the fact that we employ classes for our navs, you can certainly keep away from the list-based method totally if you prefer.
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">

<a class="nav-item nav-link" href="#">Features</a>
<a class="nav-item nav-link" href="#">Pricing</a>
<a class="nav-item nav-link disabled" href="#">Disabled</a>
</div>
</div>
</nav>
You can likewise apply dropdowns in your navbar nav. Dropdown menus call for a covering element for setting up, thus make certain to use different and embedded components for
.nav-item
.nav-link
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" 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="navbarNavDropdown">
<ul class="navbar-nav">

</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="http://example.com" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown link
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</li>
</ul>
</div>
</nav>
Set various form controls and components inside a navbar by using
.form-inline
<nav class="navbar navbar-light bg-faded">
<form class="form-inline">
<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>
</nav>
Straighten the contents of your inline forms along with utilities as needed.
<nav class="navbar navbar-light bg-faded justify-content-between">

<form class="form-inline">
<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>

</nav>
Input groups operate, too:
<nav class="navbar navbar-light bg-faded">

<span class="input-group-addon" id="basic-addon1">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="basic-addon1">
</div>
</form>
</nav>
Several buttons are assisted just as component of these navbar forms, too. This is also a fantastic tip that vertical placement utilities can possibly be applied to coordinate several sized features.
<nav class="navbar navbar-light bg-faded">
<form class="form-inline">
<button class="btn btn-outline-success" type="button">Main button</button>
<button class="btn btn-sm align-middle btn-outline-secondary" type="button">Smaller button</button>

Navbars may likely include little bits of content with help from
.navbar-text

</ul>
<span class="navbar-text">
Navbar text with an inline element
</span>

Style the navbar has certainly never been really much easier due to the merger of theming classes and
background-color
.navbar-light
.navbar-inverse
.bg-*
<nav class="navbar navbar-inverse bg-inverse">
<!-- Navbar content -->
</nav>
<nav class="navbar navbar-inverse bg-primary">
<!-- Navbar content -->
</nav>
<nav class="navbar navbar-light" style="background-color: #e3f2fd;">
<!-- Navbar content -->
</nav>
Although it's not needed, you can cover a navbar in a
.container
<div class="container">
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<a class="navbar-brand" href="#">Navbar</a>

</div>
As soon as the container is within your navbar, its horizontal padding is taken away at breakpoints below your specified
.navbar-toggleable-*
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<div class="container">
<a class="navbar-brand" href="#">Navbar</a>

Operate setting utilities to put navbars inside non-static settings. Pick from settled to the top, positioned to the bottom, or stickied to the top . Consider that
position: sticky
.sticky-top

<nav class="navbar fixed-top navbar-light bg-faded">
<a class="navbar-brand" href="#">Fixed top</a>
</nav>
<nav class="navbar fixed-bottom navbar-light bg-faded">
<a class="navbar-brand" href="#">Fixed bottom</a>
</nav>
<nav class="navbar sticky-top navbar-light bg-faded">
<a class="navbar-brand" href="#">Sticky top</a>
</nav>
Navbars can certainly incorporate
.navbar-toggler
.navbar-collapse
.navbar-toggleable-*
Navbar togglers can possibly be left or right aligned with
.navbar-toggler-left
.navbar-toggler-right
Without any
.navbar-brand
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarTogglerDemo01">
<a class="navbar-brand" href="#">Hidden brand</a>
<ul class="navbar-nav mr-auto mt-2 mt-lg-0">
<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>

<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">Navbar</a>

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

<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>

In certain cases you want to utilize the collapse plugin to trigger covert subject someplace else on the page. For the reason that plugin handles the
id
data-target
<div class="pos-f-t">
<div class="collapse" id="navbarToggleExternalContent">
<div class="bg-inverse p-4">
<h4 class="text-white">Collapsed content</h4>
<span class="text-muted">Toggleable via the navbar brand.</span>
</div>
</div>
<nav class="navbar navbar-inverse bg-inverse">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
