Check out OpenCube: Professional Site Navigation Software. I am sure that this is old news for some, but I recently came across this site. It is a web-based app that allows you to create CSS/JavaScript menus. While the menus are not that aesthetically polished or sophisticated, and the GUI itself is very cumbersome, there is a lot there that you can explore for coding examples and ideas. If you are checking out other code and see id=”qm0″, class=”qmmc”, class=”qmparent”, (anything prefixed with “qm…”), you are looking at OpenCube code.
Oh, and their .js is minified, but you know how to fix that…
