It seems you are using laravel pass your parameter to controller and then from controller pass value to view.
1. To Send GET params from controller to blade
public function youcontroller(Request $param)
{
$main_title = $param->main_title;
return view('bladeView', compact('main_title' , 'main_title_options' ));
}
2. Then in your view( .blade) check if you are getting proper values and do.
{{ ($main_title == $option->value) ? 'selected' : '' }}
