Select2 Custom Field DEMO + onDisplay issue

Hi Guys,
Started yesterday a demo for a new Select2(js) custom field. Can be use on single selection or multiple. Use optgroup (inclusive and exclusive).
Try options: @@Greetings,Hello,Hi,Bye,@,@color,blue,red,green,@

start an inclusive group with one @(NAME) and finish with @
start an exclusive group with @@(NAME) and finish with @

Works with onEdit in profile. Shall be working too in registration since it's same code. Will try to add all features along the road...

However, Mark and Jason... I have issues with onDisplay... the profile view loads dynamically so I'm **** for the regular code. I figured out that I would need a display_content.php and display_content.js to load the javascript inside your own code, however the documentation for javascript doesn't exist yet therefore I have no idea to make it work (works sometimes if quickly load but we got the point). Can you help on this one.

Anyway, I share my stuff as usual, hope it might be of some use. I'm aware of few bugs already but feel free to post any comment, will help to develop quicker.
