SortableJS, a JavaScript library for creating reorderable drag-and-drop lists, has been wrapped into a component for Microsoft’s Blazor web application builder and renamed Blazor Sortable.

Once users are comfortable with the drag-and-drop interface, they can transition to text-based programming languages like Python or C++, which are also supported by the Raspberry Pi Pico.

Don't look for Microsoft to provide drag-and-drop functionality for Blazor, though it can still be done via JavaScript interop.
