Under attributes you can of course get validation messages pop-up underneath the attribute in question. I want to have the same validation message underneath a file dropper when a picture has been uploaded. Is this possible?
Do you just want a custom message that signifies that your upload has succeeded?
In this case you can make a ‘validation message’ (where ever you want it) that is only visible depending on a Boolean value. Once you trigger the file-upload and it has success → change the boolean to true and make it show the message.
