I created a menu by Menu block module. I added a link 'to /news' in the first level. The second level are news categories (taxonomy items). I want to display the categories (2 level) on node page. How to do that?
Try the Taxonomy Menu Module. It creates you a menu item for each term which you then can place in your menu.
Try this: menu_block
It allows you to have different levels of your menu in different blocks.
Just create a menu-block for your main navigation(only level 1) and a second for level 2 only. Set the second menu-block only to show up on
node* or what ever you need.
