| block_core_navigation_submenu_render_submenu_icon() X-Ref |
| Renders the submenu icon SVG for the Navigation Submenu block. return: string SVG markup for the submenu icon. |
| block_core_navigation_submenu_get_submenu_visibility( $context ) X-Ref |
| Returns the submenu visibility value with backward compatibility for the deprecated openSubmenusOnClick attribute. This function centralizes the migration logic from the boolean openSubmenusOnClick to the new submenuVisibility enum. Backward compatibility handling: - Legacy blocks (saved before migration, never opened in editor): Have openSubmenusOnClick in database. Parent Navigation block passes it via context. We prioritize openSubmenusOnClick to preserve the original behavior. - Migrated blocks (opened in editor after migration): JavaScript deprecation removes openSubmenusOnClick and sets submenuVisibility. We use submenuVisibility since openSubmenusOnClick is null. - New blocks (created after migration): Only have submenuVisibility, openSubmenusOnClick is null. We use submenuVisibility. return: string The visibility mode: 'hover', 'click', or 'always'. param: array $context Block context from parent Navigation block. |
