[Cyril Wolfangel]

Hi,
I need to use this extention, but i don't know how to add the special 
input information into my form field.
I try this but doesn't works
Label : | fieldname = input | texte default | datepicker = true
( I need this : <input type "text" name="edit1" id="edit1" 
datepicker="true">)

Thanks
