How to design nested 3 level json : <p>I have an object like below:</p>

<pre><code>Parent: { Child1: [ {name:'grandchild1', value:'abc', checked:true}, {name:'grandchild2', value:'pqr', checked:false} ], Child2: [ {name:'grandchild3', value:'abcd', checked:false}, {name:'grandchild4', value:'pqrs', checked:true} ], parent2{...........}.... };
</code></pre>

<p>How can I make it nested JSON.</p>

<p>Just like in root: parent1, parent2...
Child: children1, ....( Corresponding to parent)
Grandchildren: based on children</p>

<p>Please guide me how can I make it?</p>
