Grab and Drop Object on Grid

Hi, I’m rather new to Blueprint but I get the basics as I’ve followed quite a lot of tutorials now. I managed to create a grid where each tiles are detected by the character when moving and I am able to grab and drop an object. Now I have searched everywhere but couldn’t find an answer or a hint as to how would I grab an object and drop it only on a grid tile. I want to be able to move with the object but when I drop it I want it to snap to a tile on the grid everytime… anyone has an Idea how I would achieve that? Or maybe point me to a tutorial that could help? Thanks.
