Quick Answer
Manage plugin state with .data(): var state = $el.data("myPlugin") || {}; state.isOpen = true; $el.data("myPlugin", state). State is tied to the element - automatically cleaned up when the element is removed. For complex plugins, use a class or plain object to represent the state, and store a reference to the instance in .data().
