What is the current behavior?

By default, the menu is expanded at the “lg” breakpoint, and there is no option to alter this behavior.

GitHub Issue Number: #892

What is the new behavior?

By default, the menu is collapsed at the “lg” breakpoint, with a newly introduced parameter “expandedNavigationMenuPreferred” governing this behavior.

Does this introduce a breaking change?

• Yes
• No

To revert the new default behavior, the newly added parameter “expandedNavigationMenuPreferred” must be set to true.

Testing

Manual tests.
