Hide div inside iframe

Hi,

I built a new page with one iframe that contanis a back-end page. i want to show the page in front-end but I want hide one div inside them (admin menu side bar).

So my problem is to hide one div inside an iframe. I tried a long time but I did not succeed.

I tried that way:

Metabox:

<iframe id=”myframe” style=”position: relative; left: -50px; top: -50px;” src=”http://10.0.0.***/***/wp/wp-admin/edit.php?post_type=event&page=calendar&#8221; width=”1400px” height=”1200px” frameborder=”0″></iframe>

Script n Style:

jQuery(document).ready(function($){
$(document).getElementById(“#adminmenuwrap”).style.visibility = “hidden”
});

Thanks in advance
Regards
