HTML / Javascript子菜单？

This image illustrates best what i want:

I have a standard HTML page which is interacting with a mysql database. One of of my pages, i want to have sub menus which load info ajaxly based on a tab (not refreshing the whole page). I don't want to reinvent the wheel...as this has been done so many times before. Any ideas?

Thx

Based on the onClick event of the tabs, use jQuery to make an Ajax call (with get/post arguments) to get the content you need from the server.
