Materials that you'll need:
1) Purchase Dreamweaver
2) Purchase Xara Menumaker or Webstyle
Install Xara plugin to Dreamweaver. Once you have plugin installed goto your theme.html file in your favorite theme's directory amd open it in dreamweaver. Inside the theme.html file there should appear to be a table structure. Here you may insert and or manipulate where you would like to insert your drop down menu's. Do this and then publish them.
