[TYPO3-english] ST template checkboxes

[Sergey Alexandrov]

Thanks, Jigal

I thought about something like that, but it will not work:

See, if BOTH options selected, the "options" field will have value of 3 
(0011 binary) and "First option" will not be rendered, only the second.
And so on: if 3 first boxes checked, "options" field will have value of 
8 (0111). In his case neither first nor second options will be rendered :(

There is an "prioriCalc" stdWrap property 
(http://typo3.org/documentation/document-library/references/doc_core_tsref/4.1.0/view/5/1/)
and it does some simple math calculations except bitwise operators :)

Will patch the core then or just write userFunc ....

Interesting, having such data structure in the core but no render TS 
function ....

Thank you,
Sergey
