When you open your SiteSpinner click Help on the top menu and then choose Tutorials, in the list there you'll find Drop-Down Menus. Another place where you can find this tutorial is SS online help search for menus and choose Making a Dropdown Menu from the list. There are also some other alternatives like javascript and flash menus that can be incorporated in SS although sometimes there is a risk that not all of them are working in all browsers, you have to check that. Some examples of javascripts reminding of the one you refer to are here and here.
awesome, thank you for the links. I am looking at the first javascript code and was wondering how do I add that code to my header section, and the other code to the body part in sitespinner? Also, do I have to stick to that color for the menu?
In order to add the code to your header copy and paste your code into Page Editor > Custom Header > New Header. The body part click on the code icon (on the left) and paste the code in the text editor. If you want to change the colour then you have to replace the two (or all three) images that are included 'menubg' and 'menubgover'.
One way is to use some other images of your choice and rename them to 'menubg.gif', 'menubgover.gif' and 'menuarrow.gif' (those names are referred to in your codes). Another way is to use the images that come with the codes and change their colours in the shading editor. I would choose the latter but the choice is yours.
