An update to this unresolved question;
Certain menu items auto-expand (while others do not) when any page set as the index page is displayed.
The only information I can find on the plugin site is;
“Auto-expand will automatically expand sub-menus on page load using the inherent CSS classes allocated by the WordPress custom menu system.“
and
“Auto Expand Based on Current Page/Item
If selected the menu will use the inherent WordPress menu system for identifying the users current page and automatically expand the sub-menus. Useful if users browse to pages via other links.”
Could someone please help me understand the “inherent WordPress menu system”. This seems a bit cryptic.
Thank you 🙂
Found the problem;
I had Disable Parent Links on, but had the index page url within some parent links.
This caused those links to seen as children of the index page.
