How can I stop the button image from being dragged, and only the image?

I’m trying to make a drag and drop system, and when I drag an item, it grabs the background as well, how can I prevent this?

You’re using Self for for Drag Visual - so that’s what you get. If you hover over that pin, the tooltip will tell you that normally you’d create a new widget to represent what you’re dragging. It’s a neat solution if you want a more advanced behaviour:

This way you can have an animated drag & drop with all the bells and whistles in the world. If you’re after something simpler, you could just plug something else that’s relevant, the icon perhaps?
