Hello ,
I didn’t think a high resolution screen shot would be necessary because the widget is provided in the very first part of the post. You can simply double click the function in the provided file( Drag and Drop Widget ) to expand it and see the inner workings of the function. Just to be clear, the attached file is the entirety of the widget shown in the pictures above. I posted another link to it above in this post.
Note: To use the widget you can navigate to the content folder of your project and place it there after it is unzipped. If you have the engine installed in the default directory this folder can be found by going to Documents > Unreal Projects > Your project > Content
