Drop-down menu for use in my tabled menu bar?

First, please lets not get into a discussion about the relative merits of tables vs CSS. :-)

I've created a website using Photo Shop and have a set of images in a table that comprise a horizontal menu.  If you've never seen a Photo Shop website or you are not following what I mean please see the website in question:

(text is not mine, I know it reads sort of "rural")

I need to change the menu into a drop-down menu to avoid using the sub-menus on each subsection of the web that I presently have.

The solution I have in mind should function sort of like one of the following:


... however I need to be able to insert the menu items into the current tables, use the current graphics for the initial menu item and not have them push the rest of the page around.  If you have seen the results from using Xara Menu Maker that's sort of what I want.  The above examples use positioned <div> elements that after a couple of hours of work I was not able to get to function correctly.

Oh, of course it needs to be cross-browser capable.

I'm pretty sure this is all client-side but in case it's not the website is being served in Win2K/IIS5 in regular-old ASP.

Now I'm not a java developer, I can muddle my way around a little in the code but this is a freebie site I did for the guy and I'm really out of time on it.  I can of course handle putting my own labels in the code and maybe extending an array or 3 but I'm looking for some code that will work for me without having to learn how it works first and then re-write it if you can see where I'm coming from.

Thanks in advance for any assistance, and just ask if you need more clarification.

Well as much as I understood at the first glance to that cascading menu code, you have to make some litlle changes on it, so that you can define each menu seperately with its own size, so you can use current graphics' settings for it.
is it what you are looking for?

Yes, provided it works with the tabled images and doesn't push things around in teh rest of the cells.  I guess I fail to see how it can be changed.  I'm sure it's possible it's just outside my ability.
Below is an example of how the code could be changed.

What I did was add the javascript code to yout orignal design and change the code to include your root menu items positoned as close as I could get them to the original. The sub menu items were left alone. You would have to adapt them to your needs. Things looked ok when I checked them in IE 6 and Netscape 7.

Perhaps it can get you started on your way.

The "Dropdown menu example" was not working but the zipped file named "FrontPage 2002 Sample Dropdown menu.zip" contains and example of the menu.

This menu setup is pretty simple.  Your using ASP development so why not stetp a main header and 3 additional sub headers (it looked like you would need 3 sub headers) and use ".inc" file to keep it consistent through the sub menu pages.   Once you create the first sub header then you can copy it for other two sub header and make your menu changes.  This menu use tables and css so making these changes are simple.  There is a small javascript file that is the function of the menu, but you do not need to modify it at all.

Good luck I hope it helps!
