Dropdown values with Firestore

I'm trying to create a dropdown with only country values and I can't seem to get retool to show the country name.

Adding {{ Countries.data }} returns the following:
{"country": "Australia", "countryCode: "AU", ...}
{"country": "Argentina", "countryCode: "AG", ...}
{"country": "Austria", "countryCode: "AT", ...}

Adding {{ Countries.data.country }} returns the following:

Does anyone know how to get show this as an array (as need for a dropdown) without the objects? Or even just rendering the country names in the dropdown?

Hello @cory_mayfield, and welcome to the community! You just need to adjust this to {{ Countries.data.map(item => item.country) }} and you should be good to go.
