I have this list and I need the client to choose none or one or both of them and include it in the body post request with OpenApi 3.0:
[none, apple, banana, [apple, banana]]
this is what I did so far but not sure
frut_type:
type: string
nullable: true
enum:
- null
- apple
- banana
- enum: [ apple, banana ]
enter code here
```
