html - Specifying First Nav ul With jQuery -

i'm trying use jquery plugin called menuflip on first ul navigation menu. reason, no matter do, applies menuflip of sub-menu's too.

this using start plugin:

$(document).ready(function() {     $('ul:first-child').menuflip(); }); 

this actual html navigation menu:

<div id="navigation-menu"> <ul id="flip_nav">     <li class="main-li"><a href="/home">home</a></li>     <li class="main-li"><a href="/page/202624/about" class="dropdown">community</a>       <ul class="sub-menu">        <li><a href="#">information</a></li>        <li><a href="#">rosters</a></li>       </ul>      </li>     <li class="main-li"><a href="/forums" class="dropdown">forums</a></li>     <li class="main-li"><a href="/join" class="dropdown">join</a></li>     <li class="main-li"><a href="/generalgamingnews" class="dropdown">content</a></li>     <li class="main-li"><a href="/calendar" class="dropdown">events</a></li>     <li class="main-li"><a href="teamsg" class="dropdown">competitive</a></li>     <li class="main-li"><a href="/livestream">live streams</a></li>     <li class="main-li"><a href="/store">store</a></li> </ul> </div> 

$(document).ready(function() {     $('ul:first-of-type').menuflip(); }); 

note added jquery 1.9.

edit: of course applies sumenus. inside 1 called.

solution

i had make changes plugin itself. don't understand why creators of plugin didn't build way begin - or @ least give option enable/disable children. anyway, children targeted (find()), had change things. here fiddle: http://jsfiddle.net/e2st7/2

jquery
