Can we generate interactive PDF from FrameMaker?

Hi

I have Tech Comm Suite 4.0.

I am creating a FrameMaker document where I want to add screenshots to supplement some of the steps. The intended audience comprises both who don't need the screenshots as they are familiar with the UI and those who cannot understand the procedure without those screenshots.

I tried using the Drop Down Caption and Body features of RoboHelp menu (within FrameMaker). But when I generate the PDF, I don't get the interactivity.

Is there a way I can make these screenshots optional? The final output will be PDF.

Thanks
