/**
|
||||
* Enhanced Select2 Dropmenus
|
||||
*
|
||||
* @AJAX Mode - When in this mode, your value will be an object (or array of objects) of the data used by Select2
|
||||
* This change is so that you do not have to do an additional query yourself on top of Select2's own query
|
||||
* @params [options] {object} The configuration options passed to $.fn.select2(). Refer to the documentation
