Is it possible to use TreeGrid with a local array?

I want to build a list of Nagios hosts and services which I’ve loaded into an array, it’s many levels deep however and has many different fields, a small example is:

$data = [ 'HOST1' => [ 'CONFIG' => [ 'ITEM1' => "1" ], 'STATUS' => [ 'FLAPPING' => 0, 'STATUS' => 0 ], 'SERVICES' => [ 'SERVICE1' => [ 'STATUS' => [ 'FLAPPING' => 0, 'STATUS' => 0 ] ], 'SERVICE2' => [ 'STATUS' => [ 'FLAPPING' => 0, 'STATUS' => 1 ] ] ] ] ];

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

$data = [     'HOST1' => [         'CONFIG' => [             'ITEM1' => "1"         ],         'STATUS' => [             'FLAPPING' => 0,             'STATUS' => 0         ],         'SERVICES' => [             'SERVICE1' => [                 'STATUS' => [                     'FLAPPING' => 0,                     'STATUS' => 0                 ]             ],             'SERVICE2' => [                 'STATUS' => [                     'FLAPPING' => 0,                     'STATUS' => 1                 ]             ]         ]     ] ];
