I have a dataset that contains information that I would like to use for rendering dropdown options. My dataset has a list of countries and I would like to add a dropdown that renders each country as an option. I know that I can use the getItems method to grab all the fields from the dataset and then map through the array and render an option based on the key of the field I would like to use but the problem is the dataset is very large and this would be an inefficient solution. Is there any other way to accomplish this?
