使导航选项卡可折叠，就像引导程序中的导航栏一样

Question

我想使nav-tab在移动设备中可折叠，例如引导程序中的nav-bar默认。 在这里尝试： https : //jsfiddle.net/7d3mxv3a/1/

<ul id="accountNav" class="account-nav nav nav-tabs" role="tablist">
    <li class="active">
        <a href="external-page.html" >External link 1</a>
    </li>
    <li>
        <a href="external-page.html">External link 2</a>
    </li>
    <li>
        <a href="external-page.html">External link 3</a>
    </li>
    <li>
        <a href="external-page.html">External link 4</a>
    </li>
    <li>
        <a href="external-page.html" >External link 5</a>
    </li>
    <li>
        <a href="external-page.html">External link 6</a>
    </li>
</ul>

我要这个：
