Some homepages allow you to upload documents. There is a button "choose file" and then you choose a file. After everything is ready you hit a button "upload" or "continue" the documents are uploaded after hitting the button.
Now I just came across such a webpage. Some things have to be entered, after that a few upload buttons. I choose some files, did not upload them yet, I did not click on "continue" yet.
Now the files are selected. How can I delete one of the files? There is no button to undo a select file, the file is selected and stays selected.
How can I unselect a file so it gets not uploaded when hitting "continue"?
Note: I do not want to reload the page.
