Hi,

I've a problem with a menu. Looks like this

Node level 3

- node level 4

- - node level 5

- - - node level 6

- - node level 5
Node level 3

Node level 3

- Node level 4

I have some xslt that either expand all or expand a level 3 node so the level 4 nodes are visible, but I want all the child nodes visible if there are any, so that if level 4 are visible and have child node they should be visible too. (I can change between the two with changing a 0 to 1).

The existing xslt is not something I wrote but something I have modified, and I'm not sure I understand enough to solve this... I really hope someone can help me!

Here is the xslt:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet
