title: Drop down option menu using onsen UI
body: <p>I want to develop drop down menu header as available in android navigation toolbar. I am using phonegap &amp; onsen UI Framework to develop mobile application. I can able to load sliding menu from left &amp; right side but right now my requirement is to open drop down if one should press icon display in image.</p>
  
  <p>Same list should be displayed(open) if user press option button from phone device. I am not using jquery or jquery mobile to develop mobile UI. I don't want to develop drop down menu using html5 &amp; css, so I request you please let me know some alternative way to handle it. </p>
