The new `current` method of the data adapter works in a similar way to the old `initSelection` method, with three notable differences. The first, and most important, is that **it is called whenever the current selections are needed** to ensure that Select2 is always displaying the most accurate and up to date data. No matter what type of element Select2 is attached to, whether it supports a single or multiple selections, the data passed to the callback **must be an array, even if it contains one selection**.
