Horizontal scrolling navbar bootstrap

Question

I have a navbar on the right side of my website, but if i resize the screen like a tablet screen, the navbar goes on 2 rows.

My navbar html code is basic:

<div class="nav_div col-sm-offset-5 col-sm-7"> 
        <nav class="navbar navbar-default">
          <div class="container-fluid">
            <!-- Brand and toggle get grouped for better mobile display -->
            <div class="navbar-header">
              <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-nav" aria-expanded="false">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
              </button>
            </div>
            <!-- Collect the nav links, forms, and other content for toggling -->
            <div class="collapse navbar-collapse" id="bs-nav">
              <ul class="nav navbar-nav navbar-center">
                <li data-menuanchor="blablab" class="active"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
              </ul>
            </div><!-- /.navbar-collapse -->
          </div><!-- /.container-fluid -->
        </nav>    
    </div>

I search to have an auto horizontal scrolling bar where the active tab is in the middle.

The problem is this: <div class="nav_div col-sm-offset-5 col-sm-7"></div> your col-sm-7 is not large enough to hold your content when the view-port resizes so it pushes the content to a new row.

You can change it to something like this <div class="nav_div col-sm-offset-3 col-sm-9"> as an easy clean solution.

Two solutions with Demos:

<div class="nav_div col-sm-offset-3 col-sm-9"> 
        <nav class="navbar navbar-default">
          <div class="container-fluid">
            <!-- Brand and toggle get grouped for better mobile display -->
            <div class="navbar-header">
              <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-nav" aria-expanded="false">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
              </button>
            </div>
            <!-- Collect the nav links, forms, and other content for toggling -->
            <div class="collapse navbar-collapse" id="bs-nav">
              <ul class="nav navbar-nav navbar-center">
                <li data-menuanchor="blablab" class="active"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
              </ul>
            </div><!-- /.navbar-collapse -->
          </div><!-- /.container-fluid -->
        </nav>    
    </div>

OR

You can manipulate the padding of your nav links in CSS, this allows you to still use <div class="nav_div col-sm-offset-5 col-sm-7"></div> without it breaking to a new row on screen resize.

.navbar-nav > li > a{
   line-height: 50px;
   padding: 0 5px;
}

IF you want vertical scrolling youll need to decrease the size of your columns, however this is not a good way to structure a nav if you're using bootstrap.

<div class="nav_div col-sm-offset-5 col-sm-3"> 
        <nav class="navbar navbar-default">
          <div class="container-fluid">
            <!-- Collect the nav links, forms, and other content for toggling -->
              <ul class="nav navbar-nav navbar-center">
                <li data-menuanchor="blablab" class="active"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
                <li data-menuanchor="blablab"><a href="#blablab">blablab</a></li>
              </ul>
          </div><!-- /.container-fluid -->
        </nav>    
    </div>

CSS:

.navbar{
   max-height: 40px;
   overflow-y: scroll;
}
