Almost there with Wayfinder, little help needed please

I’ve been trawling the forums for over an hour, found a read the wayfinder documentation and complete guide pdf, but i still can’t figure out how to hide all child documents.

Here’s where im at...

I’ve created a horizontal menu using Wayfinder (no problems there), usting this code i’ve managed to hide child documents of non-active pages, however when you click on a page with child documents it lists the children. How can i stop it from showing the child pages even when viewing the parent page?
