Pulsanti da rendere attivi in un pdf visualizzato su mobile.

@G_0722 

You need to switch to Hyperlinks.

I'm afraid that you're going to find that getting buttons to work with interactive PDFs on mobile platforms is very difficult, if not impossible. The range of mobile PDF readers, browser enabled add-ons and problems incorporating tap and release object states for mobile platforms make chasing button capabilities in interactive PDFs a losing battle.

Not to turn you away from your desired plans, I'd suggest that perhaps an HTML solution may serve your mobile interaction capabilities much better than anything you'll get from InDesign and/or Acrobat creating interactive PDFs.

Hope this helps,

Randy
