Hi @masterak25 ,


What's the relationship between the 2 choice columns?

In otherwords, what's the relationship between america and the 5 states from america?


Best Regards,


the countries and their respective states are in one separate sharepoint list to make this two comboboxes. i need the functions to fulfil my constraint mentioned above.

Hi @masterak25 ,


So could you tell me what's the relationship between the country and state?

powerapps itself cannot identify which country a state belongs to.

This needs to be defined in advance in the data source.


Best Regards,


the datasource is already given as separate sharepoint list. In that list has 2 columns one is country and state. i need to make cascading combobox
