There are multiple ways of doing that depending on requirements. One way is you can create a button above your whole MSO with a fill matching your paper color so that whenever it is visible, your MSO hides. In MSO last state you can create a button, onclick of which that paper color button becomes visible hiding your MSO (use show/hide button action). Onclick of thumbnail (using which MSO appears) this paper color button should hide.
I wrote this up for DPS but it works for EPUB and Publish Online as well: http://boblevine.us/digital-publishing-suite-101-how-to-hide-a-slideshow/
It sounds like what you did so I don’t understand what the exact issue is.
This was exactly what i was trying to do. But one glitch still remains, when the user flips between the states (I have previous and next navigation buttons) the empty state shows up in the loop and that is weird. Is there a way to skip the empty frame from showing up?
Two things you could do.
The first would be to include the buttons in each state so when you get to the last state the next button would actually use the go to state instead of the go to next state. The other would be to include the buttons but don’t have a go to next state in the last state or a go to previous in the first.
Thanks a lot Bob. Will try that out.
