I set up my own tt_content layout in TSconfig like
TCEFORM.tt_content.layout.removeItems = 1,2,3
TCEFORM.tt_content.layout.addItems.100 = Green Box
and added the class definition to my typoscript setup like
# Layout Green Box (100)
tt_content.stdWrap.innerWrap.cObject{
100=<tt_content.stdWrap.innerWrap.cObject.default
100.15.value = greenbox
}
in TYPO3 CMS 7.6.9. But it nothing happens in the frontend. The Layout "Green Box" appears in the Appearance > Layout dropdown but the class does not.
Did I something wrong or is there a new way since the fluid layouts in 7+ version?
