Lightning:Input – Hide (Reset) Field Level Error message Enabled by using showHelpMessageIfInvalid()
Have few Lightning:Input and Lightning:Select components in My Component A.
All the fields are having Required attribute as ‘true’.
Once fields are validated, Field level error (help) messages appear at the bottom of the field and will be there until input Field data is changed (is valid). I have used showHelpMessageIfInvalid() to enable this error message on field explicitly from controller.
