You can use cls : 'customCls' An optional extra CSS class that will be added to this component's Element (defaults to ''). This can be useful for adding customized styles to the component or any of its children using standard CSS rules. And maybe you want to check out this

EDIT:

Ext.regModel('Contact', {
    fields: ['firstName', 'lastName']
});

var store = new Ext.data.JsonStore({
    model  : 'Contact',
    sorters: 'lastName',
    getGroupString : function(record) {
    return record.get('lastName')[0];
    },
    data: [
        {firstName: 'Tommy',   lastName: 'Maintz'},
        {firstName: 'Rob',     lastName: 'Dougan'},
        {firstName: 'Ed',      lastName: 'Spencer'},
        {firstName: 'Jamie',   lastName: 'Avins'},
        {firstName: 'Aaron',   lastName: 'Conran'},
        {firstName: 'Dave',    lastName: 'Kaneda'},
        {firstName: 'Michael', lastName: 'Mullany'},
        {firstName: 'Abraham', lastName: 'Elias'},
        {firstName: 'Jay',     lastName: 'Robinson'}
    ]
});

Ext.onReady(function() {
    var list = new Ext.List({
        fullscreen: true,
        itemTpl : '{firstName} {lastName}',
        grouped : true,
        indexBar: true,
        store: store,
        listeners: {  // here you can add itemtap event and retrieve index number!
            itemtap:function(item,index, e){

                console.log(index);
                //so, now that you have index , you can access specific item
                console.log(this.store.data.items[index]);      
        }   
    },
    });

    list.show();

    console.log(list.getStore().data.items[0]); 
    // here you are accessing list store and then store data and then store item with index 0
});
