Think Solution Business, Mind and Healty

This Drupal module displays a horizontal menu in a block under which a submenu appears when an user hovers on an item.

If the menu on the current page has a submenu, it's displayed by default.
If JavaScript is not enabled, this module gracefully degrades.
Installation
Unpack in your modules folder (usually /sites/all/modules/) and enable under Administer > Site Building > Modules.
