In the Atahualpa settings I chose to prevent parent-menu-items to be clickable. That works great!

My problem is that this setting does not prevent the parent-menu-items in the breadcrumbsNAVXT trail to be clickable.

How do I prevent parent-menu-items to be clickbable in the breadcrumbsNAVXT trail?

Example on http://www.de-a.nl/organisatie/statuten :
breadcrumbs-trail is: Home »Organisatie »Statuten
Here the parent-item "Organisatie" should not be clickable as it is the parent of "Statuten".

This is just a hunch. It appears you are using the Atahualpa menu system and have created a page for that top level menu item. Perhaps if you added the Page Links To plugin you could go to that page and put # in the URL field so the page has a null link. I have used that plugin in the past in a similar way.

YES! Thanks again Larry. Works like a charm.
