Custom Style on TreeView node

Hello,

I would like to change the style of some nodes based on a condition. For example how would I change the background color of any node that has a value in a t2.date column?

It follows my TreeView widget code which is inside a view.

<?= TreeView::widget([
        'query' => MyDbTable::find()
            ->join("left join", "t2", "t1.id=t2.id_t1")
            ->select(['*', t2.date, 't1.id as id', CONCAT_WS(" ", code, name) as name'])
            ->where(['t1.id_person' => $id_p])
            ->addOrderBy('root, lft'),
        'headingOptions' => ['label' => 'Page 1'],
        'rootOptions' => ['label' => '<span class="text-primary">'.$model->getFullname().'</span>'],
        'topRootAsHeading' => false, // this will override the headingOptions
        'fontAwesome' => true,
        'isAdmin' => false,
        'iconEditSettings' => [
            'show' => 'list',
            'listData' => [
                'folder' => 'Sector',
                'cogs' => 'Machine',
                'cubes' => 'Operator',
             ]
        ],
        'displayValue' => $idp,
        'nodeAddlViews' => [
            Module::VIEW_PART_1=> '@backend/views/page1/treemanager',
            Module::VIEW_PART_6=> '@backend/views/page1/dettaglio',
        ],
        'emptyNodeMsg' => 'Neo node available',
        'showIDAttribute' => false,
        'softDelete' => false,
        'cacheSettings' => ['enableCache' => true],
        'allowNewRoots'=>false,
        'toolbar'=>[
            TreeView::BTN_CREATE => [
                'alwaysDisabled' => true,
            ],
            TreeView::BTN_CREATE_ROOT => [
                'alwaysDisabled' => true,
            ],
            TreeView::BTN_REMOVE => [
                'alwaysDisabled' => true,
            ],
            TreeView::BTN_SEPARATOR,
            TreeView::BTN_MOVE_UP => [
                'alwaysDisabled' => true,
            ],
            TreeView::BTN_MOVE_DOWN => [
                'alwaysDisabled' => true,
            ],
            TreeView::BTN_MOVE_LEFT => [
                'alwaysDisabled' => true,
            ],
            TreeView::BTN_MOVE_RIGHT => [
                'alwaysDisabled' => true,
            ],
            TreeView::BTN_SEPARATOR,
            TreeView::BTN_REFRESH => [
                'alwaysDisabled' => false,
            ],
        ]
    ]);
    ?>

Thank you in advance!

Best regards,
