How to create a page tabs without iframes now in Facebook?

开发者_开发百科is it possible to create a page tab without iframes in Facebook now? -how to add a tabs using FBML?

Facebook has already deprecated page tabs using FBML, iframe is the only method now. This is mentioned on their developer roadmap:

We will stop allowing new FBML apps, but will continue to support existing FBML tabs and apps. Instead, we recommend using iframes.

You can do that as long as your application is sandboxed.

In your application setting on Facebook:

If you enable "Sandbox Mode", the lower config will be available. However, this is not the way you should be building apps today. Iframes and web standards are the way to go.

Now, my question is, why do you want to do this?
