单选按钮选择上的下拉菜单标题分配器

Question

我有一个单选按钮和下拉菜单。基于单选按钮，我的下拉菜单被过滤。它正在被过滤。但是我的问题是，当我选择另一个单选选项时，此“选择”消失了。

有人可以帮助我吗？我不知道问题来自哪里

HTML

@Configuration
public class MyConfig {

  @Bean(initMethod="initMethod")
  public DbConfigLoader dbConfigLoader() {
    return new DbConfigLoader();
  }

}



public class DbConfigLoader {

    @Autowired
    private DbConfigRepository repository;

    private DbConfig dbConfig;

    @PostConstruct   // Optional if you dont want to add initMethod in Bean Defination
    public void initMethod(){

    // Logic for your dynamic Data load
        dbConfig = repository.findOne(1L);  
    }

    public DbConfig getDbConfig() {
        return dbConfig;
    }
}
