Hi Marcus Zierke, 1) its will behave differently for ‘checkbox’ because ‘event.target.type’ == “checkbox” in case of checkbox. It will not work for ‘radiobox’ also. 2) With ‘materialize’ I have not checked it out. 3) onChange is necessary here otherwise how can I get those values of form. 4) I am not very much sure what ‘DataForm’ you are talking about. Please explain little bit more.
