In menu settings tab set secondary links as primary links. Then secondary links will show the children of every primary link.
If the children have also subitems you will need an extra module or code to show them. A good module for showing third, fourth and lower levels of primary links is menu block.
Good luck,

Hi guys, I am a newbie. Need some instruction. I have a five primary liks and each links has several childs (say 8/9). What I want, when I will click primary links suppose "Home" it will open a specific page linked to Home with its childs. It should not show other primary links child in a page linked to "Home". Like this when I will click other primary links it will open that primary links page with childs. What I mean every primary links child should be seperated when i click links. It should not show all. How can I achieve this? Any help will be appreciated. Thanks in advance.
