Langkah2
1) Salin kod berikut
<!DOCTYPE html>
<html>
<head>
<link type="text/css" href="https://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" rel="stylesheet">

<script type="text/javascript">
$(document).bind("pageinit", onPageInit);
//variable to store menu instance
newMenu = null;
function onPageInit()
{
//create menu. First option in the third argument is menu title
createMenu("dynamicMenu1","contentDiv","Menus,menu1,menu2,menu3",menuHandler);
$("#btn1").click(function(){

});
}
function createMenu(menuId, parentId, options, menuHandler)
