Portal navigation dropdown links do not work on mobile if there's an even number of them

[darkol-asioso]

Affected Version

2026.1

Affected capability

Portal-Engine

Steps to reproduce

1. Create a portal with two pages - each with at least one child page. Make sure the pages are saved and published.
2. Open the root page on mobile or use Phone preview in admin panel.
3. Click on navigation hamburger menu and then on one of the navigation links.

Actual Behavior

Dropdown menu does not show up - we cannot access the subpages.
See attached screenshot from Enterprise Demo with two dropdowns.

Expected Behavior

Dropdown menu should show up, displaying links to subpages.
See attached screenshot from Enterprise Demo with one dropdown (the second is unpublished).

Additional info

Issue appears to be caused by the use of findAll() function instead of findAllIn() function in vendor/pimcore/portal-engine/assets/scripts/pages/shared/main-nav.js file on lines:

let $listItems = findAll('.js-main-nav__list-item', list);
let $itemToggles = findAll('.js-main-nav__list-toggle', list);
