Nice_menus is a way to create js-style flyout menus with Drupal

Installation:

1. Download the file nice_menus.tar.gz from http://drupal.org/project/nice_menus
2. Upload the file to the "modules" directory in your instance of Drupal.
3. Extract the file using DirectAdmin File Manager
4. Log into your Drupal site to enable and configure this new module.

Once you've enabled the module, go ahead and go to Administer -> Site building -> Blocks. Find "Nice Menu" in the Disabled list and chose a region for it (left/right sidebar, header, footer) and choose save blocks. Once you've done this, it will appear in the corresponding category.

You can then click configure to set some options for this module. You can give it a title, select a type of menu style, as well as set custom visibility settings. You can also chose a soure menu tree. This allows you to take any pre-existing menus you've developed and apply them to a nice_menu to quickly alter the look and feel of your site.
