Umbraco Sorter

What is it?

The UmbSorterController provides drag-and-drop sorting functionality for lists of items in the Umbraco backoffice. It handles reordering items within a container, moving items between containers, and supports nested sorting scenarios. This is useful for block editors, content trees, and any UI that requires user-driven ordering.
