Sencha Touch change itemTpl on specific items in list

Question

I'd like to be able to add class in the Itemtpl where the Item has it's field "Answered" set to "true" It sound's easy to me, but I don't know where to start..

I know I have to check if Answered is true in the tpl, but I don't know how to write in the template.. oO

        //model
    Ext.define('User', {
        extend: 'Ext.data.Model',
        config: {
            idProperty: 'Name',
            fields: [
                {name: 'Name', type: 'string'},
                {name: 'Address', type: 'string'},
                {name: 'ID', type: 'int'},
                {name: 'WebUrl', type: 'string'},
                {name: 'InfoUrl', type: 'string'},
                {name: 'Answered', type: 'boolean'},
                ]
        }
    });

    //store

    aStore = Ext.create('Ext.data.Store', {
        model: 'User',
        sorters: 'Name',
        grouper: {
            groupFn: function(record) {
                return record.get('Name')[0];
            }
        }
    });

    //full store

    store = Ext.create('Ext.data.Store', {
        model: 'User',
        sorters: 'Name',
        grouper: {
            groupFn: function(record) {
                return record.get('Name')[0];
            }
        },
        proxy: {
            type: 'ajax',
            url: '/Services/RestaurantList.ashx',
            reader: {
                type: 'json',
                rootProperty: 'users'
            }
        },
        listeners:{
            load: function(){
                var all = store.data.all;
                aStore.setData(all.slice(0,30));
            }
        },
        autoLoad: true
    });


    //the list
    list = Ext.create('Ext.List', {
        flex: 8,
        itemTpl: ['<div class="contact">{Name}</div>'],
        store: aStore,
        listeners: {
            itemtap: function(list, index, target, record) {
                mainContainer.setActiveItem(1);
                detailsPanel.setRecord(record);
        },
        plugins: [
            {
                xclass: 'Ext.plugin.PullRefreshFn',
                refreshFn: function(){
                    store.clearData();
                    aStore.clearData();
                    store.clearFilter();
                    aStore.clearFilter();
                    store.load();
                    list.refresh();
                }
            }
        ],
        grouped: true
    });

Have you looked at the docs for XTemplate? http://docs.sencha.com/touch/2.2.1/#!/api/Ext.XTemplate . In particular, look at the "Conditional processing with basic comparison operators" section.

If you don't want to use the <tpl if=""> notation, you can also use the ternary operator:

itemTpl: new Ext.XTemplate(
    '<div class="{[values.Answered ? \'answered\' : \'\']}">{Name}</div>'
),
