How do I get Acrobat to recognize the developer changes I made to a Microsoft Word document?

OK, so when I design a letter I like to do it in Microsoft Word, I am comfortable with the program and I know how to work quickly with it.  I always use the developer function to enter drop-down menus, dates, salutations, etc.   However, whenever I try to convert my Word document into a PDF.  Acrobat doesn't recognize any of the drop-down menus, and any of the developer changes that I have made.  The form field auto detection is on and I assume this is precisely what that function is for.  Please help!
