title: jQuery, slicknav plugin, long menu overflow y
body: <p>Im using the slicknav plugin for my mobile menu, but encounter the following problem:
  the menu has to be fixed on top, but my menu is rather long and for smaller screens it is impossible to navigate through all of the items.
  I tried separating the mobile trigger (positioning fixed) and the menu itself relative, but that doesn't work, as well as adding overflow-y on scroll and auto for the menu wrapper itself.
  Anyone can help me with some sort of solution or has encountered similar with this plugin?
  html:</p>
  
  <pre><code>&lt;ul id="menu2"&gt;
      &lt;li&gt;Parent 1
          &lt;ul&gt;
              &lt;li&gt;&lt;a href="#"&gt;item 3&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;Parent 3
                  &lt;ul&gt;
                      &lt;li&gt;&lt;a href="#"&gt;item 8&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#"&gt;item 9&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#"&gt;item 10&lt;/a&gt;&lt;/li&gt;
                  &lt;/ul&gt;
              &lt;/li&gt;
              &lt;li&gt;&lt;a href="#"&gt;item 4&lt;/a&gt;&lt;/li&gt;
          &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;&lt;a href="#"&gt;item 1&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;non-link item&lt;/li&gt;
      &lt;li&gt;Parent 2
          &lt;ul&gt;
              &lt;li&gt;&lt;a href="#"&gt;item 5&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#"&gt;item 6&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#"&gt;item 7&lt;/a&gt;&lt;/li&gt;
          &lt;/ul&gt;
      &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>js:</p>
  
  <pre><code>$('#menu2').slicknav({prependTo:'#mobileMenuHolder'});
  </code></pre>
  
  <p>css: (not working)</p>
  
  <pre><code>#mobileMenuHolder, .slicknav_menu{
    overflow-y: scroll;
    position: relative;
  }
  </code></pre>
  
  <p>mobileMenuHolder holds the menu and is at the bottom of the fixed div.</p>
  
  <p>Thanks for all help provided.</p>
