I have an array as below

[ {
        name: 'Asia'
        children:[
            {
                name : 'India',
                multiselect: true,
                children:[
                    {
                        name : 'Delhi',
                        id: 'Delhi',
                        multiselect: true
                    },
                    {
                        name : 'Mumbai',
                        id: 'Mumbai',
                        multiselect: true
                    },
                    {
                        name : 'Trivandrum',
                        id: 'Trivandrum',
                        multiselect: true
                    }
                ]
            }
        ]
     },
     {
        name: 'Europe',
        multiselect: true,
        children:[
            {
                name : 'Romania',
                multiselect: false,
                children:[
                    {
                        name : 'Bucuresti',
                        id:'Bucuresti'
                        multiselect: false,              
                    },
                    {
                        name : 'Sibiu',
                        id:'Sibiu'
                        flag: false               
                    }

                ]
            }
        ]
     }
]
