Hi, I am a newbie in web development. I made a CSS drop-down menu using CSS3 and PIE, but the drop-down doesn't work in IE6 and Firefox.

Usually this technique works in both browsers, without using CSS3 and PIE.

Does PIE have problems with CSS drop-down technique? How to fix this problem?

Here is my code (I use "if lte IE 6" hack in the code):
