Question: I am using iframe to display pdf(asp.net mvc3).While PDF is in the iframe menu item is not visible ,means it is hiding behind the iframe.
Can anyone let me know how to aolve this.

Thanks in advance.

Answer: 
You must request the API with the [field\_expansion syntax](https://developers.facebook.com/docs/reference/api/field_expansion/) 

These api requests works :

`$results = $facebook->api('/me', array('fields' => 'picture.height(300).width(300)'));`

`$results = $facebook->api('/me', array('fields' => 'picture.type(large)'));`
As described in [this bug](http://developers.facebook.com/bugs/129804577163441) on Facebook, you can request this via the new API "[field expansion](https://developers.facebook.com/docs/reference/api/field_expansion/)" syntax.

This works for me:

```
https://graph.facebook.com/____OBJECT_ID____?fields=picture.type(large)

```
