The sub-menus under "Mijn NPV" are restricted and just for Members. I've changed them to "public" and nothing changed in the appearence. So I set them to restricted again. The main-menu buttons "Activiteiten", "Fruitrassen", "NPV Info" and "Diverse" are public with submenus and these submenus are all dissapeared as well.
Wenn you login at the bottom of the homepage (Temp account: User: jp, Password: jpjp) you'll see that on the right side of the button "Mijn NPV" now the little arrow appears and the dropdown menus, belonging to that button, appears as well.
Wenn you go directly to one of the subpages f.i.
www.npv-pomospost.nl/NPV-info/Bestuur-en-Commissies
, you'll also see that on the right side of the button "NPV-info" now the little arrow appears and the dropdown menus, belonging to that button, appears as well. Now it is also possible to swotsch from one sub-page to the other.
I hope this gives you some usefull information to solve this issue. Thansk for your assistance!!
