You can search in the selection box, see the example values and even use our custom field explorer feature. image After selecting the field, you can press the `Save` button to save the configuration. image If this is your first remapping, a popup will appear, which reminds you that **a sync is required** for the saved changes to show their effect. image ## Fallbacks In case the selected field is removed (`undefined`), `null` or changes it's structure (`string` => `array`), the remapping will result in `null` as output. For these cases it makes sense to define one or multiple fallback values, when configuring a remapping. You can do so by clicking the `Add fallback` button in the configuration UI. image We will execute the remapping top to bottom. This means the remapping stops for each the entity (employee, candidate, job...) has soon as valid value is found. image You can also use the **Fallback to Kombo's mapping** button to include Kombo's standard mapping logic as one of the priorities in your fallback chain. This is useful when your custom field is not always populated and you want to fall back to what Kombo would have mapped by default. Learn more in the [Kombo Default Fallback](./kombo-default-fallback) guide.
