Don't use a complicated fronted MVC just for hiding and showing. Just label HTML with *_hiding and *_hideable with this plugin.

A checked box with a *_hiding class unhides the corresponding *_hideable elements. A *_hiding non-empty text input unhides the corresponding *_hideable elements. A *_hiding element with a checked child or non-empty text input also unhides the corresponding *_hideable elements.

Usage: $('#container').hiding()
