For more information on how to apply CSS classes to DevExpress Blazor components, refer to the following help topic: CSS Classes.

If your custom CSS ruleset includes only one class selector (.my-submenu in the code sample above), some property declarations can be ignored. DevExpress themes can apply predefined CSS rules that are more specific and have higher priority than a single-selector rule. Make your rule more specific to increase the priority of your ruleset. See the following help topic for an example: Apply Styles to Components. For more information about how a browser calculates rule priority, refer to the following topic: Understanding the cascade.

You can use the !important flag to override other CSS rules. However, note that this flag modifies the standard behavior of the cascade, which can make troubleshooting CSS issues quite challenging, particularly in large stylesheets.
