“Just an illusion”…. (a great 80’s song too)
Squirrel doesn’t provide drag & drop capability on its standard objects. There are some minor exclusions to this, but generally, it’s expected that you dynamically hide or show objects rather than moving them around the screen.
But hey, you’re different right!

and have a great idea that requires the ability to drag and drop an item around the screen. Well, there is an (illusionary) way to do it, using standard objects in a sneaky way. It’s not perfect, and it has some limitations, but it will get you close to your objective until the Squirrel developers have time to add it to their ‘to-do” list.
Have fun and enjoy!
