Using accordion widget as a menu in header causes footer to jump up page... (containing BC blog)

Hi all,

So I'm using an accordion panel widget as a collapsible menu in the header and I have the ol' "{tag_pagecontent} BC blog thing going on (displaying a BC blog in an HTML box on a page),

except when I publish this to BC, the footer jumps up the page and sits behind the blog content (yes, the footer checkbox is selected, no I don't have sticky footers enabled). When I remove the accordion panel and replace it with a simple "home" button (actually a hyperlinked image), the footer acts as intended.

So the issue here seems to be with the accordion panel causing a problem, but what's going on and how do I stop it so I can display the accordion menu on my blog template page?

Anyone have any ideas? Is it simple to fix and am I just overlooking something blatantly obvious because I'm tired?

Any help on this would be greatly appreciated!

Thanks.
