Here's a demo of a very old version of our list http://quietcode.com/smartlist/ It's also on github but the code is so outdated it's not worth linking to. This demo has 4000 items to show its speed with medium datasets

Everything is created dynamically. The js that creates the demo is

    userList = new QCSmartList({
        dataUrl: 'users.json',
        columns: [
            {field:'email'},
            {field:'surname'},
            {field:'firstname', header:'Name'},
            {field:'points'}
        ],
        containerId: 'user-list',
        name: 'users',
        varName: 'userList'
    });

If anyone's interested I can try and get some updated code/demo up later on today (it's only morning here)
