The movies are sortable by dragging and dropping them.
After sorting, the Order value will be updated. However, to see this, you have to refresh the page.
Movies are Simple Sortable as well as One-to-many Sortable. Therefore, you can also sort the movies of each director separately. Click on a director's name to see this.
Note: You may get unpredictable results with this demo if someone else on the web is manipulating the data simultaneously.
