Why my nav bar doesn't work? - html

Question

I'm new in bootstrap.
I'm trying to configure my menu bar. I added this line of code into my header:
<meta name="viewport" content="width=device-width, initial-scale=1">
After that, I added this block of code in my view:
<nav class="navbar navbar-default">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="#">WebSiteName</a>
</div>
<ul class="nav navbar-nav">
<li class="dropdown"><a class="dropdown-toggle" data-toggle="dropdown" href="#">Inicio <span class="caret"></span></a>
<ul class="dropdown-menu">
<li>Opcion 1</li>
<li>Opcion 2</li>
<li>Opcion 3</li>
</ul>
</li>
<li>Pagina 2</li>
<li>Pagina 3</li>
</ul>
</div>
</nav>
This is what I want:
This is what I'm getting:
I want all items horizontally, not vertically...
Maybe this is very basic, but this is the first time that I'm using bootstrap.
Could you help me, please?

You are missing a few things in your code
See a basic demo from bootstrap itself here
Take a look at navbar docs
Here is a simple working snippet base on your code.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<nav class="navbar navbar-default">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
<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="#">WebSiteName</a>
</div>
<div id="navbar" class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li class="dropdown"><a class="dropdown-toggle" data-toggle="dropdown" href="#">Inicio <span class="caret"></span></a>
<ul class="dropdown-menu">
<li>Opcion 1
</li>
<li>Opcion 2
</li>
<li>Opcion 3
</li>
</ul>
</li>
<li>Pagina 2
</li>
<li>Pagina 3
</li>
</ul>
</div>
<!--/.nav-collapse -->
</div>
<!--/.container-fluid -->
</nav>
