I use bootstrap 4.3.1 instead of 3.3.7 to fix this problem.

Maybe you can try it.

I'm making an application with bootstrap and I have a nav bar, however for some reason when I resize the page the links disappear but the toggle button doesn't show.
Here is my nav bar:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"></script>
<nav class="navbar navbar-default">
<div class="container-fluid">
<div class="navbar-header">
<div class="navbar-brand">title</div>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav navbar-right">
<li>one</li>
<li>two</li>
<li>three</li>
<li>four</li>
</ul>
</div>
</nav>
Any help to fix this would be greatly appreciated.
You don't currently have the toggle button in your code. Try placing the following before your collapse, and after your navbar-header:
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>

<li>Page 1-3</li>
</ul>
</li>

</ul>
<ul class="nav navbar-nav navbar-right">

<div class="container">
<h3>Collapsible Navbar</h3>
<p>In this example, the navigation bar is hidden on small screens and replaced by a button in the top right corner (try to re-size this window).
<p>Only when the button is clicked, the navigation bar will be displayed.</p>
</div>
you havent added a toggle button as i can see in your code
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<div class="navbar-brand">title</div>
</div>
For more details refer Navbar documentation (bootstrap)
in my case I am using bootstrap5 but class I was using old version, after changing code as below it worked for me by going though BS5 W2Schools:
<nav class="navbar navbar-expand-sm bg-dark">
<div class="container-fluid">
Recipe Book
<ul class="nav navbar-nav">
<li class="nav-item" routerLinkActive="active">

<a class="nav-link" routerLink="/shopping-list">Shopping List</a>
</li>
</ul>
<ul class="nav navbar-nav navbar-right">

<a class="nav-link dropdown-toggle" href="#" role="button" data-bs-toggle="dropdown">Manage<span class="caret"></span></a>

It works but when it comes to small viewports it stopped showing the hamburger. I have inspected the code and the menu options are there to be shown but I miss the three lines button to toggle menu visibility. What kind of mistake did I do?
Note that I didn't apply any custom css or js by now.
Now as answer ;)
You commented the HTML section of the button. See line 4 to 10. Button including 3 spans icon-bar.
you have commented hamburger menu section

You can use:
overflow:hidden;
in css or declarate it deirect in the html:
<style type="text/css">
.container-fluid {
overflow-x:hidden;
overflow-y:hidden;
overflow:hidden;
}
</style>
I hope it helps
Everything looks fine to me. You probably have some custom CSS doing something wrong. I even tried excluding "viewport" meta tag, still doesn't show overflow.

I have created a navbar containing a dropdown menu. When i click header, simply nothing happens.
Here is my code:
<nav class="navbar navbar-default navbar-fixed-top">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand icon-github" href="/"> </a>
</div>
<div class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toogle="dropdown" role="button" aria-expanded="false">
Customers
<span class="caret"></span>
</a>
<ul class="dropdown-menu" role="menu">
<li>All Customers</li>
<li><Recently added</li>
<li>Today's appointments</li>
<li class="divider"></li>
<li>Create new customer</li>
</ul>
</li>
</ul>
</div>
</div>
</nav>
There is no error in the console.
It's a simple typo: You have data-toogle instead of data-toggle.
It should work with this:
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">
Customers
<span class="caret"></span>
</a>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css">

<ul class="dropdown-menu">

If I am not wrong this is what you are looking for..
I am trying to make a 3-level collapsing navbar menu for Bootstrap, but I can't open the third level.
This is the two level menu which I have:
<link href="https://stackpath.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css" rel="stylesheet"/>
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<div class="nav-collapse">
<ul class="nav">
<a class="brand" href="#">Present Ideas</a>
<li class="active">Home</li>
<li>Blog</li>
<li>About</li>
<li>Help</li>
<li class="dropdown" id="accountmenu">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">Account Settings<b class="caret"></b></a>
<ul class="dropdown-menu">
<li>Login</li>
<li>Register</li>
<li class="divider"></li>
<li>Logout</li>
</ul>
</li>
</ul>
<ul class="nav pull-right">
</ul>
</div>
<!--/.nav-collapse -->
</div>
</div>
</div>
I thought something like this would work:
<link href="https://stackpath.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css" rel="stylesheet"/>
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<div class="nav-collapse">
<ul class="nav">
<li class="active">Home</li>
<li>Blog</li>
<li>About</li>
<li>Help</li>
<li class="dropdown" id="accountmenu">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">Account Settings<b class="caret"></b></a>
<ul class="dropdown-menu">
<li>Login</li>
<li class="item-148 dropdown parent">
Learn more <b class="caret-right"></b>
<ul class="dropdown-menu">
<li class="item-149">The Software</li>
<li class="item-150">The Project</li>
<li class="item-151">The Leadership</li>
<li class="item-152">Open Source Matters</li>
</ul>
</li>
<li class="divider"></li>
<li>Logout</li>
</ul>
</li>
</ul>
<ul class="nav pull-right">
</ul>
</div>
<!--/.nav-collapse -->
</div>
</div>
</div>
But that's not working.
Bootstrap 2.3.x and later supports the dropdown-submenu..
<ul class="dropdown-menu">
<li>Login</li>
<li class="dropdown-submenu">
<a tabindex="-1" href="#">More options</a>
<ul class="dropdown-menu">
<li><a tabindex="-1" href="#">Second level</a></li>
<li>Second level</li>
<li>Second level</li>
</ul>
</li>
<li>Logout</li>
</ul>
Working demo on Bootply.com
Bootstrap 3 dropped native support for nested collapsing menus, but there's a way to re-enable it with a 3rd party script. It's called SmartMenus. It means adding three new resources to your page, but it seamlessly supports Bootstrap 3.x with multiple levels of menus for nested <ul>/<li> elements with class="dropdown-menu". It automatically displays the proper caret indicator as well.
