Is it possible to have the sub-nodes only expanded when the root node (the one the sub-nodes are under) is selected as the current link. In other words, I do not mean click on an item to expand the node, but rather, the root node is a link and when on that page, the highlighting of the "active" link also expands its node, but not when on other pages.
to illustrate, say I have a tree menu with 3 links: Home, FAQ, and Links. Lets say Links has 3 sub-nodes: Good Links, Bad Links, and Ugly Links. I want the sub-nodes to only display when the user is on the Links page and not when on Home or FAQ.
