I am having issues with getting the off-canvas menu to open on exclusivity ios8.1. The button turns to the active state and the transparent overlay appears but no menu expands out. I have tried problem solving from other posts but no luck.

Any help would be appreciated.  

  <div class="title-bar" data-responsive-toggle="widemenu" data-hide-for="large">
    <div class="title-bar-left">
      <span class="title-bar-title"><a href=""></a></span>
    </div>
    <div class="title-bar-right">
      <span class="title-bar-title"></span>


  <div class="off-canvas position-right" id="offCanvasRight" data-off-canvas data-position="right">
    <ul class="vertical menu">
      <li></li>
      <li></li>
      <li></li>
      <li></li>
      <li></li>
      <li></li>
    </ul>
  </div>
