Off Canvas collapsed nav — parent label opens submenu instead of navigating (Indicator trigger)

Hi,

I’m using Pro with a custom header containing an Off Canvas navigation (element: Navigation Off Canvas → Navigation Collapsed) for mobile.

The collapsed nav uses a WordPress menu where “Mortgages” and “Protection” are parent items, each with five child pages. Both parents link to real published pages ( /mortgages and /protection — these load fine when accessed directly).

The problem: On mobile, I want tapping the parent label to navigate to its page, and the chevron/indicator to expand the submenu. In Navigation Collapsed → Menu → Sub Menu Trigger , I’ve set this to Indicator (not Anchor). However, on the live mobile front-end, tapping the parent label still opens the submenu rather than navigating to the parent page. The submenu’s child links work fine — it’s only the parent label that won’t navigate. The result is that the hub pages are unreachable from the mobile menu.

What I’ve already checked / ruled out:

  • Sub Menu Trigger is set to Indicator and the header has been saved.
  • Tested on the live front-end (real mobile device, private/incognito) — not just the editor preview.
  • Cleared all caches (server cache, page cache plugin) and confirmed with a fresh private session.
  • The parent menu items have valid URLs — /mortgages and /protection load correctly when typed directly.
  • Menu structure is correct: parents with five properly-nested child items.

Separately (possibly related): when I add a sixth child to either parent in the same menu (e.g. an “overview” link to the hub page, whether as a Custom Link or a Page item, nested at the same level as the existing five), it does not render in the collapsed nav on mobile — only the original five children show. Adding it as a top-level item does show. This made me wonder if the collapsed submenu is caching/limiting rendered children.

My questions:

  1. With Sub Menu Trigger set to Indicator, should the parent label navigate to its page on mobile? If so, what would stop it working here?
  2. Is there a recommended setting/markup so the label navigates and only the indicator toggles the submenu?
  3. Why might a newly-added child item not render in the collapsed submenu when the existing children do?

Thanks!
