Resize Layer Upon Loading of iFrame Content

[RamsesThePigeon]

I may be trying to do the impossible here, but I figured I'd ask nonetheless...

I have a page wherein the content is held together by a layer. Inside said layer, I have a scrollbar and an iFrame. The scrollbar is designed to target the iFrame, which works beautifully. Unfortunately, the content of the iFrame exceeds the height of the page, and thus I run into several formatting issues. I'd like to avoid the use of a scrollbar (other than the one on the user's browser,) and as such, I need a way to have the layer (and the entire page) resize itself when the iFrame content loads.

SHORT VERSION: Is there a way to resize a layer and its containing page when an iFrame contained within said layer loads its content?

Ugh, I'm an idiot... I meant that I have a drop-down menu in the layer, not a scrollbar...
