Filter Builder is some javascript UI for building up a filter in a data driven application. You've used something similar if you've built a smart playlist in iTunes.
Check out the example
Erm.. nothing really. It's a UI only component.
This is built using:
- backbone.js
- backbone-localStorage
- bootstrap
Of course! I rebuilt an earlier version of this so I could check out backbone.js. Would be thrilled if anyone bothered to even check this out.
