title: Android dropdown button
body: <p>What is this <a href="http://material-design.storage.googleapis.com/publish/material_v_4/material_ext_publish/0B3321sZLoP_HTS1LdnhrTl9TRzg/components-buttons-otherbuttons-060203_MobileDropdowns_xhdpi_006.webm">dropdown button</a>? It looks like a spinner and the animation can be found <a href="http://www.google.com/design/spec/components/buttons.html#buttons-other-buttons">here</a>.</p>
  
  <p>I tried using spinner but it's not the same. This one looks awesome! Can anybody help me find it? I need to create something similar.</p>
