Image & Dropdown menu to include within a single page.

Hi Everyone

I wonder if you can help! I am looking for a plugin that will be able to achive the following;

http://www.#sdi#.co.uk/sectors.aspx (Please remove the #’s, I didn’t want this coming up in search results)

On the sectors section of this website the menu system included in the main body of the page is something I’m looking for, although I am facing difficulty pin pointing a plugin that I can achieve the same technique. I like the small thumbnail graphic, title and drop down of sub sections.

I’m just struggling to find something like this, also my terminology isn’t brilliant yet, so I am probably searching for all the wrong things!

If someone could point me in the right direction of what to search or recommend that would be amazing.

Regards
R
