try this:

beforeShow: function(el, dp) {
    uidp = $('#ui-datepicker-div').addClass('forced-display-none').detach();
    $(el).parent().append(uidp);
    setTimeout(function(){$(uidp).css({'position':'relative','left':'0px','top':'0px'}).removeClass('forced-display-none')},200);
}

define forced-display-none as:

.forced-display-none {display: none !important;}
