PR Checklist
Please check if your PR fulfills the following requirements:
PR Type
What kind of change does this PR introduce?
What is the current behavior?
Nested submenus in the ARIA menubar examples only define a single overlay position that opens to the right of the trigger element. When there is insufficient space on the right side of the viewport, the submenu can overflow off-screen instead of repositioning.
Issue Number: N/A
What is the new behavior?
Adds fallback overlay positions for nested submenus in the ARIA menubar examples. If there is not enough space to render the submenu on the right side, the CDK overlay can fall back to opening on the left side of the trigger element, helping keep submenu content visible within the viewport.
The update is applied consistently across the basic, material, and retro menubar examples.
Does this PR introduce a breaking change?
Other information
This change only updates overlay positioning configuration in the example templates and does not affect framework APIs or runtime behavior outside of the examples.
