Hi @RohitChattopadhyay, for default support you need to hand over a customized AJV instance in which it is enabled, see [this question for more details](https://jsonforms.discourse.group/t/help-with-default-values/31).

At the moment the off-the-shelf renderers always offer the blank option, see [this issue](https://github.com/eclipsesource/jsonforms/issues/1501) for more details.
