Storyline reveal drag items one at a time, prevent dropped items to jump back.

Hello Acco ICT,

Thanks for reaching out!

It would be much easier for the community to help out if you could share a copy of your project file so we could see how your drag-and-drop interaction is setup. Would you be willing to share a copy of your project file here or in private by opening a support case so we can take a look? If you decide to share your course through a support case, we'll delete it when we're done testing!
