How can I make form field invisible until another form field is completed?

For example, you cannot fill in a comment section until you answer yes or no above.

If the dependency is on a checkbox or radio button, then use this script in the calculation script for the field that will be shown/hidden

Assume the dependency field is named "YesNo".

event.target.hidden = (this.getField("YesNo").valueAsString == "Off");

If your forms are done in InDesign you can do it from there by "hide until triggered" on the form you want hidden. And when you click a button you can use the action show/hide form. It requires less programming but the JavaScript method is possible to define even more solidly.

You can also do this in Acrobat by using the Show/hide action
