Hello everyone,
I am in need of some assistance. I struggle with JavaScript and any other language that is not HTML and CSS. Below is a code I found on DHTML Goodies. Its a neat slide down menu that I would love to use, but I am having some issues with it. First off, the menu items require two clicks, I need it to only be one (user-friendly) but in that same click it needs to expand the submenu item, secondly, the submenu items don't work, it works on the first one, but none after that. I have reached my limit of understanding on this one. :-( Thanks in advance for your help. I can only post so many characters in this post, please refer to the live site for CSS and HTML.
