Havana template with side menu is very clumpsy

I have tried Havana theme with MainWindow with side menu… But the side menu looks very clumsy as like i attached in the image below. Is that any css problem?Capture


Unfortunately, we do not support havana theme for new UI components, such as SideMenu and DataGrid. I’d recommend that you take a look at the following CSS styles: https://doc.cuba-platform.com/manual-6.8/web_theme_extension.html#web_theme_migration Thus you can migrate your application to Halo based theme with almost the same UI styles.

We are planning to remove havana theme in the next Major version 7.0.
