I'm trying to customize the form in TYPO3 V12, formerly (up to V11) I just made my own partials and templates, but in V12 I cannot get that to work. (i get confused with the directory structure for the exact spot where to have the html available) ...
furthermore V12 introduced the possibility to override the specific class value, that is form.renderingOptions.formNavigation.btnSubmitClassAttribute only that I cannot get to work either ...
in a forum I found this worked out: typo3forum.net what is wrong with that snippet ?
I sometimes get confused also what cache to clear to be sure that I have the results of the latest code ... with yaml I have no idea at all ... (but this would be a separate question)
