Thank you for this excellent module! I ran into an odd use case when trying to embed an iFrame - this is only in Safari - FF works fine.

When displayed in the collapsible block of text, the iFrame display is "garbled" and Safari throws the following error:

"Unsafe JavaScript attempt to access frame with URL [page] from frame with URL [iFrame source page]. Domains, protocols and ports must match."

The same iFrame displays perfectly when not enclosed in the collapsed text block. Ideas? Any assistance much appreciated!

Hi! This module does cause Drupal to include the `collapse.js` file. This is going to do things to the elements of the created fieldset to make them collapse; in particular it is going to try to change the display properties. If the iframe references a different server, I'm guessing that Safari sees this as some sort of possible XSS attack, and errors out. I don't think there is any way to solve this. I suppose you could try having the iframe load a page on your domain which has within it an iframe to the external site, but that's ugly, awkward, fragile, and unlikely to work anyway.

Sorry, but I don't think that this can be solved...
