Hi @tivinayz ,
Yes you should be able to do this in Quick Sight based on how I am understanding your use case. What you need to do is Quick Sight supports this natively through cascading filter controls.
Edit your city filter control, and enable “Show relevant values only”, then select your country control as the parent. After that, picking USA in the country filter will automatically limit the city dropdown to only Chicago and Tampa.
One thing to note is that both controls must use columns from the same dataset, the child (city) must be a dropdown or list style pulling values from the filter (not “specific values”), and the parent (country) must be a string filter control or a string/integer/numeric parameter control.
Here are a couple of resources to reference as you set this up: filter controls docs and a previous community post that walks through a similar scenario.
Hope this helps!
