public @interface ConfigGroup
```
Indicates that a given class can be injected as a configuration object. A configuration group can contain multiple nested items and configuration groups.
Configuration group properties cannot be Optional or null. It is expected that, in the event that a group property can be disabled, this should be done using a boolean property (preferably the unnamed property or a enabled property). For example:
```
 
quarkus.extra-fast-mode         = yes
quarkus.extra-fast-mode.gadgets = 20

 
```
Or:
```
 
quarkus.laser-beam.enabled    = true
quarkus.laser-beam.mount-mode = sharks
 
 
```
