Hi Mike!
It sounds like you are trying to hide all layers besides the base layer when a learner scrolls back on the seek bar. I'd be happy to help with that!
Currently, that type of functionality would not be possible in Storyline. However, I would like to share a couple of workarounds you may find useful:
- Adding a trigger that requires clicking outside of an image (on subsequent layers) to close that layer and return to the base layer.
- Adding a hotspot near the seek bar with a trigger that closes the subsequent layer when the learner hovers over the hotspot.
I've also attached a copy of the sample file I used for your reference.
Please let me know if you have any more questions!
