Select2 3.4.6 usage

Select2 3.4.6 usage

Hello all, I am trying to figure out how to implement a jQuery plugin of Select2 3.4.6 http://ivaynberg.github.io/select2/#documentation on my website.  What I am trying to do is Multi-Value select box select values from a field from my MySQL database.  Is that possible with Select2?  If so, how can I implement it?
