Research direction

Start in MenuItem.js, focusing on the disabled and aria-disabled handling described in the issue, and inspect the disabled-item CSS behavior. Reproduce the flyout interaction with a disabled item after its trigger, then verify that moving onto either disabled variant closes the flyout just like a non-flyout item.

Written by the indexing model from the issue text.

Description

Describe the problem

In a Menu with containsFlyout, a flyout submenu stays open after the pointer moves from the flyout trigger onto a disabled item.

Hovering an enabled item without a flyout correctly calls setFlyoutRef(null). Disabled items never get that hover:

  1. isDisabled: .pf-v6-c-menu__list-item.pf-m-disabled has pointer-events: none, so onMouseOver does not fire.
  2. isAriaDisabled: MenuItem skips onMouseOver when isAriaDisabled is true, so setFlyoutRef(null) never runs.

How do you reproduce the problem?

  1. Open a Menu with containsFlyout.
  2. Include a flyout item, then a disabled item (isDisabled or isAriaDisabled) immediately after it.
  3. Hover the flyout item until the submenu opens.
  4. Move the pointer onto the disabled item.

Expected behavior

The flyout closes, same as hovering any other non-flyout item.

Is this issue blocking you?

No, however there is no workaround without avoiding hard-disabled items.

What is your environment?

  • OS: macOS

  • Browser: Chrome

  • Version: PatternFly React 6.6.0

What is your product and what release date are you targeting?

OpenShift Virtualization (kubevirt-plugin)

Any other information?

Seen in MenuItem.js: onMouseOver on the li is a no-op when isAriaDisabled is true. CSS: pointer-events: none on disabled list items.
