Recently, I picked up the LWIS.NET CSS Dropdown Menu for a project that I’ve been working on. In my opinion, this is a great menu system with a few different templates (horizontal & vertical) for easy customization.
The one trick that I picked up when using this template is that you need to add some code to get the drop down effect to work. Basically, adding
onmouseover="" inside the li elements with submenus will allow the hover CSS events to perform as intended. By default, the iPhone will ignore hover CSS events unless you specify a onmouseover event handler (even if it is blank). Thanks to commenter twenty205 for the original idea.
