    Default

    This is working for me using the root config:

    Code:
    var store = Ext.create('Ext.data.TreeStore', {
        fields : [
            'id',
            'object',
            'name',
            'quantity'
        ],
        root   : {
            expanded : true,
            children : [
                {
                    id       : 1,
                    object   : 'fruit',
                    name     : 'apple',
                    quantity : '40',
                    leaf     : true,
                    parentId : 1,
                    iconCls  : 'task-folder'
                },
                {
                    id       : 2,
                    object   : 'PC',
                    name     : 'HP',
                    quantity : '2',
                    iconCls  : 'task-folder',
                    expanded : true,
                    children : [
                        {
                            id       : 21,
                            object   : "sand",
                            name     : "apple",
                            quantity : "50 kg ",
                            leaf     : true,
                            parentId : 2
                        },
                        {
                            id       : 22,
                            object   : "mud",
                            name     : "mango",
                            quantity : "100 kg ",

                }
            ]
        }
    });
