You'll need to tell us more, and probably provide a screen shot or two. First, you're not using the correct terminology. What do you mean by a "pop up"? Is this a button? If it's a button, what is the action you have set? Have you put the button on a Master Page or the document page? How did you export the PDF file. What application are you viewing the buttons in?
Yes this is a pop up button. No I have not placed the button on a master page. I am popping up the definition for various words through out the entire document.
I have attached some PDFs for you to view.
I hope this helps.
A-I wanted you to see how I created the buttons for the Definition (I want this to pop open when the word is clicked)
B- This is the button for the Word that will be clicked on so the Definition pops open
C- This is how I export it to Acrobat
D- This is how it apears after it is exproted and I click on the word. Please note the Definition does not pop open.
Did you ever get a resolution to this? I am having the same problem. I'm setting a graphic as a "Hidden until triggered" button. I am then setting another graphic to "Show/Hide Buttons & Forms" with the event "On Release or Tap." (I've read somewhere else where I shouldn't use the event type "On Click" for the iPad Interactivity.) Would love to get an answer or a workaround. When published on the Adobe Content Viewer, or exported as an interactive PDF, the "Hidden until triggered button" never shows.
Also looking for a resolution to this problem. Having the same issue with a table of contents pop up built on a master page. Some button elements show and some do not when exported to PDF.
