[TYPO3-dev] Nested tabs in Flexforms?

[Carey O'Shea]

Hi,

I'm trying to create "nested tabs" in a Flexform for an extension. I
can't find any examples of this, although I do recall seeing it sometime
ago. 

I have read:
http://typo3.org/documentation/document-library/core-documentation/doc_core_api/current/view/7/1/
and
http://typo3.org/documentation/document-library/core-documentation/doc_core_api/current/view/4/2/#id2818801
and
http://wiki.typo3.org/index.php/Extension_Development%2C_using_Flexforms
to no avail.

I'm just not sure how to write the Flexform XML to achieve this. I'm
sure it's very simple, but I can't guess.

Does anyone have any examples? That would be all I need.

Any help is appreciated.

Kind Regards,
Carey.
