How to dynamically change the select when a value has been selected?

I want to realize that after China is selected, the Area can be automatically changed to the corresponding list.
```
settings = {
columns: {
region: {
title: 'Region',
editor: {
type: 'list',
config: {
list: [{
value: 'China',
title: 'China'
}, {
value: 'Korea',
title: 'Korea'
}]
}
}
},
area: {
title: 'Area',
editor: {
type: 'list',
config: {
list: []
}
}
}
}
```
