Thanks for the invitation.
I can think of two methods for your data structure. One is not to use value.id as the value, but to use $index as the value. It will be easier to handle later.

The second method is to monitor the data changes of s_style, such as adding ng-change callbacks to select, and then using the new data directly in the page, for example.

$scope.change = ()=>{
    $scope.currentItem = $scope.arr.find(v => v.id === $scope.s_style);
}
