I created a regular Drupal menu with links to catalog pages in it (I tried to do the catalog menu with taxonomy menu first - didn't work). Some of the branches don't expand properly. You can see the site here: http://www.nufland.com/domain/nettisivut/
The "Valikko" is the primary links menu on the left side. "Kauppa" is the shop. When you click "Kauppa", it expands as it should. But when you click "Lisaosat", it doesn't expand although there's two branches under it ("Basic ja Medium" and "Corporate"). You have to click on the main sheet all the way to some product page before the correct branch expands in the menu (for instance: "Basic ja Medium" -> "Wordpress-verkkokauppa").
Any idea what could be wrong? I'm really puzzled by this. I've spent hours to solve this issue.
