Yes, I'm using two texfield.
The timepicker is used in "Uhrzeit KOMMT" and also should be used in "Uhrzeit GEHT"
I extended the Script and it is working, thank you.
jQuery('[name="ff_nm_timepicker[]"]').wrap( '<div class="input-group clockpicker"></div>' );
jQuery('[name="ff_nm_timepicker[]"]').after( '<span class="input-group-addon"><span class="glyphicon glyphicon-time"></span></span>' );
jQuery('.clockpicker').clockpicker({
placement: 'top',
align: 'left',
autoclose: true
});
jQuery('[name="ff_nm_timepicker2[]"]').wrap( '<div class="input-group clockpicker"></div>' );
jQuery('[name="ff_nm_timepicker2[]"]').after( '<span class="input-group-addon"><span class="glyphicon glyphicon-time"></span></span>' );
jQuery('.clockpicker').clockpicker({
placement: 'top',
align: 'left',
autoclose: true
});
