This speeds up the UI and avoids hitting the API too much. Set the `allowEmpty` prop when you want to add an empty choice with a value of `null` in the choices list. Disabling `allowEmpty` does not mean that the input will be required. If you want to make the input required, you must add a validator as indicated in [Validation Documentation](./CreateEdit.md#validation). Enabling the `allowEmpty` props just adds an empty choice (with `null` value) on top of the options, and makes the value nullable. diff --git a/docs/List.md b/docs/List.md index abc885f95f2..803adc03901 100644 --- a/docs/List.md +++ b/docs/List.md @@ -207,7 +207,7 @@ const PostList = props => ( ) ``` -In many cases, you'll need more than simple object manipulation.
