Validation on label

My requirement is when a user enters some text in a lane label, there must trigger a validation like the label user has entered must not be duplicate that is the label name must not be label name of other lane. Please suggest me if it is possible. Many thanks.


What did you tried to do and what were you struggling with?

Please consider looking into examples (like this) as a starting point.


I am also looking for some validation after editing the label…Is there a rule for label change?

Thanks and Regards
