About Dynamic Drop-Down List "Name" and "Value"

Hi,

I have two question about that.

First question ; I created two dynamic dropdown custom property called via external source ( With vRealize ORchestrator );

My vRO action code is ;

....

....

return ["Production,"Development"];

....

....

But, I want to write "Name" and "Values" different like picture below . Is that possible ?

return [{"name" : "Production", "value" : "PROD"}] --> this is not working...

My second question is ;

When I click the first dropdown, second drowdown values are coming but i want to first values set as default. Because i'll hide second dropdown and values should be set as default without user selection.

Thanks.
