Here is a thread regarding a draggable map:
The key item is @MarkHunte's Hype doc: map.hype.zip (496.1 KB)
I've created another map ("map_JHSv1.hype.zip") based on Mark's example that has a clickable rectangle that moves in accordance with the map being dragged. This rectangle element triggers a simple one line JavaScript "alert()".

Please note there is no zooming in this Hype demo.
