get fbml comments to automatically show form

I'm writing facebook app in fbml (not in iframe).

I added comments with <fb:comments ...> and it appears to work. However, to add a comment, user has to click Add a comment... link to see the textarea and post button.

I am wondering is开发者_如何学Python there a way to automatically show the form? I want it to really look like here:

developers.facebook.com/docs/reference/plugins/comments

(with or without the like button)

well... to answer my own question:

it's documented at
developers.facebook.com/docs/reference/fbml/comments
The showform parameter.

Maybe it will help someone.
