title: How to make "navbar-fixed-bottom" slide up when button is clicked in responsive mode? (bootstrap)
body: <p>Currently Twitter Bootstrap's navbar at the bottom (used as footer) slides "down" when the button is pushed on a phone screen or narrow window. </p>
  
  <p>I want the menu to slide "up" instead of the default "down".. Any ideas on how I can do this with twitter bootstrap?  </p>
  
  <p>the code used in the view layer of the navbar footer is as follows:</p>
  
  <pre><code>&lt;footer id="footer" class="navbar navbar-fixed-bottom"&gt;
      &lt;div class="navbar-inner"&gt;
          &lt;div class="container"&gt;
              &lt;button type="button" class="btn btn-navbar dropup" data-toggle="collapse" data-target=".show-footer"&gt;
                  &lt;span class="icon-bar"&gt;&lt;/span&gt;
                  &lt;span class="icon-bar"&gt;&lt;/span&gt;
                  &lt;span class="icon-bar"&gt;&lt;/span&gt;
              &lt;/button&gt;
  
              &lt;div class="nav-collapse collapse show-footer"&gt;
                  &lt;nav&gt;
                      &lt;ul class="nav pull-right"&gt;
                          &lt;%= g_about_link(yield(:title)) %&gt;
                          &lt;%= g_contact_link(yield(:title)) %&gt;
                          &lt;%= g_faq_link(yield(:title)) %&gt;
                          &lt;%= g_careers_link(yield(:title)) %&gt;
                          &lt;%= g_privacy_link(yield(:title)) %&gt;
                          &lt;%= g_quotes_link(yield(:title)) %&gt;
                          &lt;%= g_terms_link(yield(:title)) %&gt;
                          &lt;li&gt;&lt;a href="http://news.railstutorial.org/" target="_blank"&gt;News&lt;/a&gt;&lt;/li&gt;
  
                      &lt;/ul&gt;
                  &lt;/nav&gt;
              &lt;/div&gt;&lt;!--/.nav-collapse --&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/footer&gt;
