Question

Is it possible to rename node from “children” to any other name as per requirement of tree structure in extjs tree. I am using json for tree structure as follows:

name: '.',

children: [{
    name:'Basic Ext Layouts',
    expanded: false,
    children:[{
        name:'Absolute',
        id:'absolute',
        leaf:true,
    },{
        name:'Accordion',
        id:'accordion',
        leaf:true
    },{

Check this http://docs.sencha.com/ext-js/4-0/#!/api/Ext.data.TreeStore-cfg-defaultRootProperty

You could look into mapping and convert properties of the field http://docs.sencha.com/ext-js/4-0/#!/api/Ext.data.Field

I believe you could setup converting of all items you need using them.
