Today I updated the Biotic Index page. Previously, I had used KineticJs, but that library is no longer maintained and I noticed a significant reduction in functionality with the drag animation. So, I substituted that for the “draggable” feature in JQuery UI. So much simpler and better performing too.
I am about to start work on a series of pages for elementary science that will heavily use drag-drop and sorting of JQuery UI. Stay tuned!
