Unable to select menu options below option that has four level

Hello,

Before creating a new issue, please review the existing issues and read the available documentation about the theme.

Please note that the menu system in the Solo theme does not support a fourth-level menu.

Thank you!

Hello,

Based on valuable feedback from the Drupal community, Solo officially will supports fourth-level navigation menus in the next release.

Why This Matters
Many users requested the ability to create deeper, more complex menu structures — especially for large sites with multi-level content hierarchies, product catalogs, or mega menu requirements.

Previously, Solo focused on a clean, accessible 3-level menu structure, optimized for performance and simplicity. However, after carefully evaluating real-world use cases and listening to user feedback, fourth-level menu support has been added — with full consideration for:

• Accessibility best practices (ARIA roles, keyboard navigation)
• Responsive behavior on mobile and desktop
• Automatic submenu positioning (smart flip logic)
• Clean, maintainable CSS and JS handling
• RTL (Right-to-Left) language support

Best wishes,

This morning I updated my development site to Solo v1.0.19 and modified the Unit & Leader Resources menu to have two fourth level menus since the release notes indicate that the menu system has been upgraded to support fourth level menus.

When the mouse is moving down the third level, the fourth level for the option will appear if it exists. However, the menu will close before the mouse gets down to the third level menu option below the option that has the fourth level.

No subtheme is in use.

I've attached a screen capture showing the issue. The mouse cursor gets to just above the next menu option before disappearing.

Hello,

The fourth-level menu has been thoroughly tested and confirmed to support the following:

1. Accessibility best practices, including ARIA roles and full keyboard navigation
2. Responsive behavior across mobile and desktop devices
3. Automatic submenu positioning using smart flip logic
4. Full RTL (Right-to-Left) language support
5. Integration with all core menu features available in the theme settings

Based on the screenshot you shared, it appears that you're still viewing an older version of the theme. Please clear both Drupal caches and your browser cache to ensure you're seeing the latest updates.

For your reference, I’ve attached a screenshot of the fourth-level submenu in action. This feature is now live on the demo site under:

Solo's Feature → Typography and Fonts → Google Fonts → Heading Fonts
