Feature Request: DropUp option

[gabelloyd]

I'd love to be able to utilize something similar to Bootstrap's dropup functionality.

http://getbootstrap.com/components/#btn-dropdowns-dropup

I pasted a little gist here: https://gist.github.com/alwaysbrightblue/ee3e6f40cd498cb88409

It follows the bootstrap method of putting the dropup class with the parent group. With the Bootstrap Select plugin, this worked, so I'm just trying to figure out how to run Font Chooser like this.

Thanks!
