Question

1-й массив =

 {"bhks": [{"id": 1, "title": "1BHK"}, {"id": 2, "title": "2BHK"}, {"id": 3, "title": "3BHK"}, {"id": 4, "title": "4BHK"}, {"id": 11, "title": "1R.T.B.K"}, {"id": 12, "title": "2R.T.B.K"}, {"id": 13, "title": "3R.T.B.K"}, {"id": 14, "title": "4R.T.B.K"}, {"id": 15, "title": "1R.T.B"}, {"id": 16, "title": "2R.T.B"}]


2nd array =
[ {
              name: 'B.H.K.',
              id: 0,
              // these are the data or 'sub items'
              data: [
                {
                  name: '1 BHK',
                  id: 10,
                },
                {
                  name: '2 BHK',
                  id: 17,
                },
                {
                  name: '3 BHK',
                  id: 13,
                },
                {
