Drop Overlay

A styled overlay appears when files are dragged over the drop zone. Customize the overlay message and appearance.

What you should see: an overlay that appears across the drop target as soon as a drag enters the window, and disappears on drop or leave — so users can see where the file will land.

<upload-dropzone asp-upload-url="/api/upload/upload"
 asp-multiple="true"
 asp-drop-overlay="true"
 asp-drop-overlay-text="Release to upload your files"
 asp-auto-upload="true"
 asp-progress="true">
</upload-dropzone>
