Update field value according to another field

Hi,

I am having an issue with chained selects. Is there any way to change values of other fields according to another field’s value?

I created a sandbox so that it is easy to look at. If you select a currency from first select, let’s say “usd”, the country select doesn’t select any option. As you can see in the state of the form, “country” value is still “IE” (the previous value).

I would like to select the first country available for a given currency. So, I thought removing <option /> it would work but it doesn’t. Any idea how to solve this without wrapping the form and send data to its parent component? Is there any way to solve this just using RFF?

Thanks.

Seems like this could be handled with a Declarative Form Rule, no?

In case someone is interested how I solved my needs, check this sandbox out.
