Integrate this plugin with custom html menu

Hi.
I love your plugin! But I need help, is there any way we can integrate GTranslate into our website (via WordPress) as a dropdown menu? (not as a dropdown widget as provided by your plugin). Here is my code for html. Can you help me where to put the gtranslate plugin codes to be integrate here. Thank you in advanced!

• <b><?=$lang_now?></b> <i class=”fa fa-angle-down” aria-hidden=”true”></i>
  <div class=”triangle”></div>

<li class=”li-eng”><i class=”sl-flag flag-usa”><div id=”usa”></div></i> <span class=”active”><?php _e(‘English’, ‘gtranslate’); ?></span>

<li class=”li-zh”><i class=”sl-flag flag-de”><div id=”chinese”></div></i> <span><?php _e(‘Chinese (Simplified)’, ‘gtranslate’); ?></span>
