How to make use of the jQuery Plugin option for Multi-select component?

I am using a Multiple Select Component, and see that there's a jQuery Plugin option. I tried to do some research, and found only this reference to it:

"Added erichynds Multiselect JQuery Plugin Files" from release documentation found at http://pedroalves-bi.blogspot.com/20...s-of-them.html

How do I make use of it?

Thank you
