Dashboard variable dependency

In Grafana …My data source is prometheus …
I need to maintain a mapping,so that based on the first drop-down custom variable ( E.g “nokiaran”) selection …the second custom variable needs to be populated ( E.g “nokia-5g-slice”) based on the mapping :

nokiaran —> nokia-5g-slice

How to achieve that ?

Please let me know.

Thanks,
Nilanjan
