may i create input with css class or add custom html5 data-xxx="" attribute?
You can extend the existing form element and modify their .ftl freemarker files. See https://github.com/jogetworkflow/jw-community/blob/5.0-SNAPSHOT/wflow-core/src/main/resources/templates/textField.ftl
thank you. @walterbut i planed operation can add simple css class for some input for call jQuery function like my old system
example
.datePass -> call datepicker and select date before today
.dateFrom and .dateTo -> call datePicker and make date range from value between 2 input
.postcode -> limit user can fill only 4 digit of postcode
See https://dev.joget.org/community/questions/27985051/make-calculations-and-update-in-real-time-fields. Use FormUtil instead.
