[TYPO3-project-formidable] renderlet:CHECKBOX - subelements?

[David Krüsemann]

Hi list,

is there any way to use 'subelements' for renderlet:CHECKBOX?

E.g.:
checkbox1
--checkbox1.1
--checkbox1.2
checkbox2

Unchecking checkbox1 should uncheck all subelements of checkbox1 (= 
checkbox1.1 & checkbox1.2)..

Any help appreciated,
David
