DropMenu from iFrame

I'm currently developing a toolbar for chrome and i have some issues with my dropMenu. So basicelly my too开发者_StackOverflow社区lbar bar is a iframe, and i want to put a dropmenu in it. But the problem is that my dropmenu only stay in the iframe and what i want is that it overflow out of the iframe.

Let me show you a printscreen of my wish :

Are you talking about a Chrome extension or plain old HTML?

If HTML, are you able to do the opposite and make the main page your toolbar with a huge <iframe> containing the main website. This is how StumbleUpon structures their layout and their toolbar has dropdown menus.

Realise though that any website that employs frame-busting code (like Facebook, Twitter and StackExchange network websites) won't ever be able to be toolbar-ed.

I think your only hope is to make the iframe as high as the drop down is, and use a transparent background on your iframe with allowtransparency="true".
