Responsive side toggle menu with adsense

1) Script Title: Responsive side toggle menu

2) Script URL (on DD): http://dynamicdrive.com/dynamicindex...togglemenu.htm

3) Describe problem: I'm using adsense on my website with the Responsive side toggle menu. However, what happens is that the ads often load before the side menu flips out from the side thus pushing the page to the right and activating the horizontal scroll bar because the adsense ads occupy the whole width of the screen. I'm using asynchronous ads.

I was thinking if there was a javascript that let the side menu (class="sidetogglemenu") load before the rest of the page. Or is there some other work around?

Can someone help?

Thanks.
