Let's create a test page in blazor and use DragulaDropula here. Page Test.razor:

<DraggingZone Width="100vw" Height="100vh">
    <h1>Some test here!</h1>
    
    <Draggable ItemToDrop="@("Banana!")">
        <div style="background-color: yellow; width: 100px; height: 100px; color: white;">
            <span style="background-color: darkorange">The banana</span>
        </div>
    </Draggable>
    
    <hr />
    
    <DropTarget OnDrop="@(model => _result = model.ItemToDrop)">
        <div style="background-color: sandybrown; width: 250px; height: 250px; color: black;">
            The banana box
        </div>
    </DropTarget>

    The result is @(_result).
</DraggingZone>

    private object _result = "nothing";
}
