Allows persistent and isolated state handling.
Quick Answer
Store plugin state in .data(): $(el).data("myPlugin", {isOpen: false, speed: 400}). Retrieve: $(el).data("myPlugin").isOpen. Update: var state = $(el).data("myPlugin"); state.isOpen = true. This ties state to the DOM element, so it's garbage collected when the element is removed. Avoids global variables and keeps state scoped to the instance.
