Description:

I would like to request a feature that allows users to hide the navigation bar. While it is possible to hide it using CSS, having a built-in option to prevent it from rendering would be more efficient.

Proposed solution:

Introduce a new prop (e.g., hideNavBar) that, when set to true, prevents the navigation bar from rendering.

<Datetime hideNavBar={true} />
