There may be cases when you wish to show or hide certain fields in your PDF form; for example, if the user clicks a button, a new group of fields is displayed. You have several options to select from when showing or hiding fields: you can elect to show or hide an individual field by setting the field’s General properties, or you can write your own custom JavaScript to show and hide fields based on user action (for example, if a user hovers over a button or another). As another option, you can create a button that will show or hide specific fields when pressed.
