Try this
$(document).ready(function (e) {
var test = 0;
$('#one').children('div').hide().css({
'overflow': 'hidden'
});
$('#one').hover(function () {
$(this).children('div').stop(true, true).show('slow');
}, function () {
$(this).children('div').stop(true, true).hide('slow');
});
});
$(window).scroll(function(event) {
if ($(window).scrollTop() >11) {
$('#one').children('div').stop(true,true).show();
}
});
Hope this helps,Thank you
