<p dir="auto">When you click on the triple horizontal lines to un-collapse  the topbar then go back to a full size window and try to open a dropdown, the dropdown no longer opens.</p>
<p dir="auto">To see the issue occur in jsfiddle, you will probably need two monitors, because it does not got from the mobile nav to the desktop nav.</p>

<p dir="auto">This is when enabling the responsive grid framework. I have this code:</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="&lt;div class=&quot;navbar navbar-fixed-top&quot;&gt;
    &lt;div class=&quot;navbar-inner&quot;&gt;
        &lt;div class=&quot;container&quot;&gt;

            &lt;a class=&quot;btn btn-navbar&quot; data-toggle=&quot;collapse&quot; data-target=&quot;.nav-collapse&quot;&gt;
                &lt;span class=&quot;icon-bar&quot;&gt;&lt;/span&gt;
                &lt;span class=&quot;icon-bar&quot;&gt;&lt;/span&gt;
