Hello, Sanjay,
Thank you for the screenshot and the example.
This occurs as when the list is opened it is still without value and the validation is still not met.
As this validation is shown automatically by the browser, we have not to option to hide it with code.
In general, we recommend using our Form component when working with forms as it provides many functionalities inducing validation where we have control over when the validation message is shown or hidden:
