Hello shreens,
Thanks for reaching out to us!
I”m assuming this is in regards to setting up the default Venue within the calendar settings? Unfortunately what you’re describing isn’t currently available and would require some customization of the Calendar settings. However, this does sound like it could be a good feature for future development. If you would like, you can suggest this feature on our UserVoice page for consideration.
However, since you’re using Community events, by setting the default country as India you should see a text input field on the event submission form that your users will see rather than the state dropdown. Is that how it is functioning on your site?
Thanks!
