Dynamic menu - Hit or Miss
Edit Menu > Form Options: does not always show when opening a Form PDF. In Acrobat Standard DC it is hit or miss as to if the Edit Menu show the Form Options selection.
What makes the 'dynamic menu' feature sense a pdf form?
Edit > “Form Options” > is visible (default) in following two cases -
1. A reader extended PDF is opened in Acrobat.
2. A distributed PDF.
The menu option is also, available in same session for a non-Reader Extended PDF (or non-distributed) if they are opened with a Reader Extended PDF (and/or Distributed PDF).
That ways the “Edit > Form Option” stays visible until user exit Acrobat application.
Please note, Edit > “Form Options” > does not appear when we are creating form from scratch because as an author he/she has the advantage of using Prepare Form Tools.
