Snap options for Drag-n-Drops in Storyline

I came across this thread because I wanted to know how to control the amount of offset when an object is dragged and dropped on top of a drop target. There is no setting to type in the number of pixels to control how far off the offset should be if you are doing a direct drag and drop.

So if you are using "Stack Offset" as your Drop Target Option, then you will have to do the following to control the amount of offset:

1. Setup the object that you want to be destination for the drop items, but DO NOT set these objects up as the drop targets.
2. Create a separate set of drop targets that are offset from the actual objects in step #1. Set those to be the official Drop Targets. You can use regular or custom shapes for this, and set them to have no fill and no outline.
3. in the Form view, designate the correct Drop Items to match with the Drop Targets in Step #2.
4. Go into Preview to test if the offset distance is correct. Adjust the boundaries of the Drop target shapes and repeat the Preview process until it drops the item at the correct distance. So for example, if the drop offset is too close, move the Drop Target shape further away from the "real" drop object from Step #1.

This is an imperfect method because your drop items and targets may be of different shapes and on-screen arrangements. In my case, I had a list of terms and a list of symbols, so the alignments were pretty easy to do.
