    data: [
        {id: 0, show: 'Battlestar Galactica'},
        {id: 1, show: 'Doctor Who'},

        flex: 1,
        filter: {
            // required configs
            type: 'string',
            // optional configs
            value: 'star',  // setting a value makes the filter active.
            itemDefaults: {
