loadData is used to load a single option, it will affect the rendering of the value
Just remove the loadData parameter

@ajuner Hi, I have 4 level areas(province, city, district, town). Due to reduce local storage size, I only cache 3 level areas(province, city, district). So for level 4(town), the only way is use loadData to load remote data by parent area code. Maybe there is a better way to solve this problem?

Hi, @ajuner , I update my CodeSandbox example to make things clear.
